[[Category:Configuration Files]]
This page has been renamed from "Cumulus.ini" to preserve the early history of that page.
= Initial Configurations =
The main ''Cumulus.ini'' [[:Category:Configuration Files| configuration file]] is located in the directory in which you installed Cumulus.exe. It is a text file containing initialization parameters used by the Cumulus 1.x.x, or Cumulus MX, application; and is read '''only''' when Cumulus starts up. Cumulus '''re-writes''' the contents of the application configuration screens to the file when it ''shuts down''. For Cumulus MX, the file-name must start with a capital letter, and all the characters used within the file must be within ASCII range.


The information that was on this old Cumulus.ini page has been moved into separate pages for Cumulus 1, MX early releases, and MX latest releases.
A second ''Cumulus.ini'' may be stored in the reports sub-directory, this only contains a [[#Section:_MainForm|single section]] and relates to the screen used for NOAA reports.


=History of this page=
The parameters listed can change the look of Cumulus, hold basic information about your location, amend the way Cumulus interfaces with your weather station, and hold the settings used to interface with your website, and with various external websites. The list below was created for Cumulus 1.x.y, and applies to the latest formal release; for any beta please refer to announcements or the separate page referenced below for any variations.


This page has proved the most complicated of all those in the Wiki to maintain:
If you are using an old version, then ''checking the release information may be advisable'' to identify the sections applicable to your build, and to identify if the parameters allowed within those sections may be a subset of those listed below as available in latest release.
# Settings change extremely often
#* Therefore it is a lot of effort to keep the documentation up to date
#* It is obviously easiest if an update is made here as soon as the settings change, sometimes that happens (perhaps by developer doing an update here)
# The design of configuration menus/screens/pages to edit the settings periodically changes
#* This means information about how to change settings often depends upon which release someone is using
#** In turn that means, either Cumulus users of latest release, or those using an earlier release, will struggle with the documentation
# Developers often provide limited information about settings,
#* Sometimes new settings are mentioned in an answer in a forum post, and do not get mentioned as a change in release announcements
#** This means that finding accurate information to update this page requires an awful lot of research that is very time consuming


The above observations applied for the legacy software, when Cumulus 2, and then 3 (MX), came along the documentation was originally split. When MX started (in 2019 to early 2020) to try to replicate much of what Cumulus 1 offered, it made sense to reuse what was written on this page for Cumulus 1, instead of duplicating it on a second page.
= Upgrading to New Build =
Installing a new build of Cumulus (whatever version) over the existing installation does not affect this settings file. No build of Cumulus contains a 'Cumulus.ini' file. If Cumulus software detects a 'Cumulus.ini' when it starts, it looks in that for settings; if it does not find the file, then Cumulus will expect you to tell it some settings, others have defaults. See Cumulus Help, release announcement, and other provided documentation for more.


Then from mid 2020 to early 2021, there was rapid development of MX by the new developer, and MX began to increasingly diverge more and more from the legacy configuration, this page reflected that by introducing sub-sections (Cumulus 1 only, MX only, and both).
= File Structure =
From early 2021 onwards that 3 sub-section design for this page failed because new MX releases began to diverge from earlier MX releases. In other words, parameters that had existed at an early MX release, were no longer used by later releases. It was possible, but increasingly more and more difficult, to track new parameters to add that were added at particular releases, so the documentation got more and more obsolete.
The main file consists of a number of sections, each with a heading delimited by '[ ]', (although the order in the file may be different to that in this article). Parameter lines are in the form 'attribute=value' and grouped by those sections.


To sum up, it was impossible for this page to show information for the legacy software, for early MX releases, and for later MX releases. The response was to move off this page anaything not relevant to the latest MX release, and to restructure this page based on how MX settings are altered, rather than where a parameter appears in the file.
Some [[#Sections_dealing_with_interfaces_to_external_sites|sections]] relate to the external websites that Cumulus can optionally supply with updates. These are set by configuration screens and the whole sections will always be present. If you do not use those external services their parameters will be set to the defaults.


Each new version of cumulus may add additional parameters set by revised configuration screens (these initially appear at the end of the relevant section), and/or permit additional parameters to be added manually (these can be inserted anywhere within the section).


==Steve Loft Era==


<big>The configuration file content relating to the legacy software (e.g. 1.9.4) has been moved to [[Cumulus.ini_(Cumulus_1)|legacy page]]</big>
== Completeness of this list ==
If you spot a parameter that is missing from this list (check you are looking in the right section, and under the correct sub-heading where a section is sub-divided for ease of using this article), then please add it to this Wiki article. None of the authors who have contributed so far can claim completeness. Sometimes a search on the forum for something else reveals a mention of an additional parameter that can be added to the file but has not been previously added to this list.


There have been over a thousand builds of Cumulus version 1 and much of this article has been written based on experience in using Cumulus, it may not reflect every parameter that can be manually added to the file, although it does reflect all those linked with settings made on various screens.

== Beta builds ==
'''CURRENTLY CUMULUS MX specific parameters are listed on [[Cumulus.ini (Beta)|Cumulus.ini(Beta)]] page.'''

If you are using a beta build, there may be changes to the information shown below with additional sections and/or additional parameters (attribute=value) under test. Brief details of such changes will be given in the support forum announcement for the relevant build. New sections and/or attributes and/or values for beta versions of Cumulus are not listed here until the version becomes 'live' however there is a [[Cumulus.ini_(Beta)|page]] that details the additional parameters available in the Beta version once they have become established, but for details of beta tests see [http://sandaysoft.com/forum/viewforum.php?f=2 the forum].

= Editing the file =

== Initialisation ==
When Cumulus 1.x.y is run for the very first time, the ''Station settings'' screen within the '''Configuration''' menu is displayed, so that the basic minimum settings can be entered into a 'Cumulus.ini' that it will then create. Should you accidentally delete Cumulus.ini this would happen again, so it is always best to take a backup of the complete Cumulus directory and sub-directories so nothing is lost in such a situation.

See [[Setup]] for further advice, noting in particular that some settings (such as units, date/time formats) should stay unchanged.

== Settings controlled by application ==
Many configuration parameter lines are changed from the various application edit, view, or configuration screens, and so making any amendments using those screens should ensure your replacement values are acceptable. You should never edit these parameter lines directly in the file ''while Cumulus is running'', as when Cumulus shuts down it will replace your amendments to these parameters with the contents of the relevant application Edit/View/Configuration screens.


''You can edit them in the file with Cumulus stopped'', but beware of selecting invalid values for these parameters, generally it is safer to use the application to edit them (unless you are importing values from another setup), and Cumulus will read the new values when it is next restarted.
== Settings independent of application ==
Some configuration settings can only be applied by editing this file to insert a new parameter line; they do not appear anywhere in the configuration screens. Cumulus does not write these values back out to the file on shut down, so they do not appear with default values - in other words, you need to ''add'' them if you want to set them. Make sure you place these additional parameters in the correct section as listed below.
=== Editing outside Cumulus ===
*It is best to take a copy of the existing cumulus.ini file before you make any changes (either by using application screens or by editing the file), so you can return to the original if necessary.
*If your system is configured to use a comma for a decimal separator, then you should use a comma in any decimal values that you set in this file.
*You should use a text editor (not a rich text editor nor word processor) to edit this file as only letters, numerical digits, decimal separators and the equals symbol are allowed in any parameter. If you use a spreadsheet program to make use of the manipulation it offers, ensure it is set to output in pure text.
*The parameter lines (attribute=value) can be in any order, but must be in the correct section. You might find it helpful to sort the attributes within a section into alphabetical order, to ''ensure you have no duplicates'' and to make it easier to find the particular parameter line you may wish to edit in the future.

= File Contents =
== Introduction ==
The entries shown in the 'parameter line entry' column include the default value from the configuration screen where applicable, a typical example value where appropriate, or just the attribute and an equals sign where there is no typical value.
The section called "[FTP site]" should obey that use of capitals and lower-case.

== Section: Station ==
See individual parameters for specific instructions on setting them. In many cases this is by using Station Configuration Screen, but if the parameter line does not exist in your file, then insert it using a file editor as per instructions above.

| This page was created for the legacy Cumulus 1 software (up to 1.9.4). If you look at the history tab of this page, user‎ '''Shamrockspider''' created this page at 12:55 on 27 August 2009 for the purpose of '''Documenting the cumulus.ini file content and its function.'''
|Type= -1
|Station Type as set by the checked radio box in the [[Cumulus_Screenshots#Configuration_Menu_Screens|Station Configuration Screen]], Station Type block. For details of [[Supported_Devices]] click that link.
*-1= default value, indicates a selection from those below must be made
*0=Vantage Pro station
*1=Vantage Pro2 station
*2=WMR-928 station
*3=WM-918 station
For Oregon Scientific stations and similar re-badged stations (Huger, Radio Shack etc) which have a serial port connection, if your model is not listed, try WM-918 if your station has wired connections, and WMR-928 if it is wireless.


Back in 2009, the file was fairly simple, and therefore documentating it was also fairly easy.
*4=Reading from file [[EasyWeather_Format#Usage_of_easyweather.dat_fields_for_Cumulus_input_of_latest_record: |EasyWeather.dat]] (using EasyWeather software version 6.2, or earlier, running continuously with Cumulus). Fine Offset weather stations that record Solar and UV measurements output to [[EasyWeather_Format#EasyWeatherPlus.dat| EasyWeatherPlus.dat file]] when Easyweather software version 6.x is running. This has the same fields as easyweather.dat, plus two extra fields for Solar and UV data at the end, and so Cumulus can understand the fields you must also have '''LogExtraSensors=1''' set.
'''NOTE:''' You can also use ''Type=4'' if you want to run Cumulus with reduced functionality without a weather station attached, to view historical observations. A full set of (historic) files in the ''data'' subfolder copied from a system with a weather station attached is needed, but in this case, the [[#Introduced for problems with Fine Offset family:| EWFile= ]] attribute should be at its default of not having any filename value.
*5=Fine Offset/Watson/MyDEL/Nevada, etc (without solar measurement sensors (with or without solar recharging))
*6=WS2300 (For all La Crosse WS23xx models)
*7=Fine Offset/Watson/MyDel etc with Solar Sensors
*8=[[WMR100-200_Protocol|WMR100]]
*9=[[WMR100-200_Protocol|WMR200]]
*10=Instromet (with optional extra solar sensors or without)
|-
|Model="your Model description"
|The weather station model description - you choose what text appears for this on (from version 1.9.x) 'Display' settings screen within Configuration menu - the field is at the bottom left of that screen).
|-
|Port=0
|Selected in the Station Configuration Screen Settings block. Com port in your computer which is connected to your weather station if connected via a serial port. Defaults to port 0.
|-
|Latitude=0
|You are advised ''not'' to directly edit this parameter in the file, but to type Latitude (unsigned) Degrees, Minutes, Seconds and select 'N' or 'S' in the Station Configuration Screen Location block. Value in this parameter is Latitude in Decimal Degrees based on what you have entered, Positive for North, Negative for South
|-
|Longitude=0
|You are advised ''not'' to directly edit this parameter in the file, but to type Longitude (unsigned) Degrees, Minutes, Seconds and select 'E' or 'W' in the Station Configuration Screen Location block. Value in this parameter is Longitude in Decimal Degrees based on what you have entered, Positive for East, Negative for West
|-
|LatTxt=
|You are advised ''not'' to directly edit this parameter in the file, but to type Latitude Degrees, Minutes, Seconds in the Station Configuration Screen Location block. Latitude in text string format of hemisphere D, M and S. HTML ampersand codes are used for spaces and unit characters.
|-
|LonTxt=
|Longitude in text string format of hemisphere degrees, minutes and seconds. HTML ampersand codes are used for spaces and DMS characters.
|-
|Altitude=0
|your station altitude (default is zero) as entered in the Station Configuration Screen Location block. See Cumulus Help for that screen. See next parameter to choose unit.
|-
|AltitudeInFeet=1
|Altitude measurement unit for value in previous parameter is set in the Station Configuration Screen Location block.
*0 = metres Above Sea Level
*1 = feet ASL
|-
|PeakGustMinutes=N
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line can be added in the [Station] section of the Cumulus.ini.
*With this parameter, N is the number of minutes over which Cumulus calculates its highest wind gust.
*Without this parameter, the default of 10 minutes, the international standard duration, is used.
*If you select 60, then Cumulus would calculate rolling 60-minute highest wind gust speeds.
*To be in line with met stations in Cz, select 30.
|-
|AvgSpeedMinutes=N
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line can be added in the [Station] section of the Cumulus.ini, if you have set the next parameter so that Cumulus does its own calculation of average wind speed.
*With this parameter, N is the number of minutes over which Cumulus calculates its average speed, if you have Cumulus set to do this with the next parameter enabled.
*Without it, the default of 10 minutes, the international standard duration, is used if Cumulus is set to calculate average wind speeds.
*If you selected 60, then Cumulus would calculate rolling 60-minute average wind speeds.
*To be in line with ASOS stations in USA, select 2.
|-
|Wind10MinAverage=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled (default), Cumulus will display the value supplied by the station. This is a 10 minute average for Davis stations, but an average over a shorter period for Oregon Scientific and Fine Offset stations, see [[FAQ#Cumulus_is_showing_a_different_wind_speed_compared_to_my_console]].
*1 = Enabled, Cumulus will calculate and display a N-minute average wind speed where N is defined by the previous parameter if present, otherwise defaults to 10, the international standard duration used to calculate average wind speeds.
|-
|UseSpeedForAvgCalc=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled (default), Cumulus will display the average wind speed value supplied by the station, see [[FAQ#Cumulus_is_showing_a_different_wind_speed_compared_to_my_console]].
*1 = Enabled, Cumulus will use the longer-term 'speed' values in the average speed calculation. The preceding 'Wind10MinAverage' option must be enabled for this parameter to have any effect.
Note that there isn't really any point enabling this option for Davis stations, as their 'longer-term speed' is a 10 minute average anyway; neither for La Crosse stations, as they only supply one wind speed anyway.
|-
|RoundWindSpeed=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled (default), Cumulus will display the wind speed value to the precision used by the station.
*1 = Enabled, this setting causes wind speeds to be rounded to the nearest integer.
|-
|AvgBearingMinutes=N
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line can be added in the [Station] section of the Cumulus.ini, with this parameter N is the number of minutes over which Cumulus calculates (by treating the wind as a vector and taking into account the speed as well as direction) its average bearing. Without it, the default = 10. See next parameter for behavoir when calm.
|-
|UseZeroBearing=0
|Set this in the Station Configuration Screen Settings block.
*0 = Disabled, Cumulus displays the current bearing read from the station (i.e. the last direction the wind was blowing from before it became calm). Note that the average wind bearing will always display zero bearing if there has been no wind for the last N minutes (where N is defined by previous parameter if present but defaults to 10), as the average bearing takes wind speed into account.
*1 = Enabled, Cumulus display a bearing of zero (and '---' for the compass point) when the wind is calm
|-
|CalculatedDP=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled, Cumulus will display the dew point value supplied by the station.
*1 = Enabled, Cumulus will calculate the dew point instead. This avoids the restriction in the Oregon Scientific stations where the dew point can never be below freezing point.
|-
|CalculatedWC=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled
*1 = Enabled, Cumulus will calculate the wind chill instead of using the value supplied by the station. You should set this if you have specified any calibration values for wind and/or temperature, so that Cumulus can also apply those adjustments to the wind chill.
Note that some stations (Fine Offset, for example), do not make a wind chill value available to Cumulus. For these, Cumulus always calculates it.
|-
|UseWindChillCutOff=1
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. Purpose is to disable 'calculate [[Wind chill]] only if temperature less than 10&#176;C rule'.
*0 = Disabled, Cumulus will use any wind speed of 3 mph or more, to modify the temperature, and determine the wind chill ignoring the temperature criterion
*1 = Enabled (default), Cumulus will use both 10&#176;C temperature and 3 mph wind speed criterions to determine if wind chill applies.
Note if your station is a type that supplies wind chill to Cumulus; that ''CalculatedWC=1'' is needed for this setting to have any effect [i.e. you need to set Cumulus (see parameter directly above) to calculate the wind chill as this setting cannot change how your weather station calculates wind chill].
|-
|ChillHourThreshold=45
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. The temperature threshold is specified in the units that you use in Cumulus (see [[Heat/cold_degree_days_and_Chill_hours]]). The default is 45 degrees Fahrenheit (or just over 7 degrees Celsius) if the parameter has not been included.
|-
|ChillHourSeasonStart=10
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. The season start figure is the calendar month number (1=January to 12= December). The default if this parameter is not specified is October (month 10).
|-
|RolloverHour=0
|Log roll over time as selected on the Station Configuration Screen
*0 = midnight
*9 = 9am/10am
|-
|Use10amInSummer=1
|Daylight saving correction for 9am roll over
*0 = Use 9am in summer (use 10am not checked on Station Configuration Screen)
*1 = Use 10am in summer selected on Station Configuration Screen
|-
|SnowDepthHour=9
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. This line needs to be added in the [Station] section of the Cumulus.ini, it is the [[Weather_Diary|Snow lying/falling]] roll over time (time when yesterday's values in log.xml are forgotten) - Allowed values are 0 to 23 and represent the time to the nearest hour that snow depth measurements are taken.
*0 = midnight (default)
*9 = 9am,
*13 = 1pm etc.
Note this time is independent of your rollover time selections in the two preceding parameters.
|-
|WarnMultiple=0
|Set as 'Stop 2nd instance' in the Station Configuration Screen Program Settings block. Controls behavoir for Multiple Instances of Cumulus running on PC. Requires a Cumulus restart if value toggled, before new behavoir will take effect.
*0 = Disabled, (default) Multiple instances allowed.
*1 = Enabled, prevents multiple instances of Cumulus from running.
|-
|ConfirmClose=0
|Selected in the Station Configuration Screen Program Settings block. Toggles Confirmation you wish to close Cumulus application after telling it to close
*0 = Disabled, application will close immediately
*1 = Enabled, application will prompt for confirmation that you wish to close it (do not use this if you might suspend/standby/hibernate your computer)
|-
|CloseOnSuspend=1
|If this is selected, in the Station Configuration Screen Program Settings block, Cumulus will close if you suspend/standby/hibernate your computer. You should not select the previous parameter 'ConfirmClose' if you use this option.
*0 = Disabled, application will not close if you suspend/standby/hibernate your computer (it is highly recommended you close Cumulus manually before your computer is put into suspend/standby/hibernate state)
*1 = Enabled, application will close on suspend/standby/hibernate of your computer (recommended if your computer can go into any of these states when left alone)
|-
|DataLogInterval=2
|Selected in the Station Configuration Screen [[Cumulus_Screenshots#Station|Data log interval]] block on the right hand side and defines frequency of logged information in the [[Monthly_log_files]] and, when applicable, in [[Extra_Sensor_Files]].
*0 = 1 min
*1 = 5 mins
*2 = 10 mins (default)
*3 = 15 mins
*4 = 20 mins
*5 = 30 mins
Notes:
*For a Davis station set to match your station logging interval. (Otherwise you may activate the 'feature' in the Davis stations where they send the entire contents of the data logger when Cumulus asks for the data since it was last running). See Readme.txt.
*For some station Types, Cumulus only reads latest readings while it is running, and missing station readings are not captured if Cumulus is restarted.
*For other makes as ''Cumulus on restarting is able (see next parameter) to read logged data from your station'' you can choose to match Cumulus and station logging intervals, then the frequency of logged information will be same regardless of whether Cumulus is running continuously or restarted (this improves accuracy of any averages calculated).
*Some Cumulus users set this Cumulus logging interval to be one of the two shorter times so they retain the maximum measurement detail in case of any need to correct rogue measurements, but have set their station logging interval at a longer time so that the station does not overwrite the memory locations over the longest period they might be away. In this case, the frequency of logged information will change between the periods Cumulus is running and the catch-up readings from station logger when it is restarted.
|-
|UseDataLogger=1
|Cumulus 1.x.y: Selected in the Station Configuration Screen Settings block.


Some settings were in [[Cumulus_Screenshots#Configuration_Menu_Screens|configuration screens]], and the file was arranged so that those settings were stored under a heading that generally (not in every case, for historic reasons) reflected the screen name. Documenting these was comparitively easy, the setting could be found easily and its allowed values could be easily tested.
Cumulus MX: This parameter (attribute=value) is added directly to the file in the [station] section, it does not appear on the settings screen.
*0 = Disabled, at start-up, Cumulus will not download data from the station's data logger (if it has one) but just start with next observations.
*1 = Enabled (Default), at start-up Cumulus will download data from the station's data logger (if it has one) to catch up from the point where Cumulus was last shut down. See last parameter for advice re station logging interval.
|-
|WindUnit=0
|[[Wind_measurement#Wind_Speed|Wind speed measurement unit]] used by Cumulus (as selected in the Units block of Station settings screen within '''Configuration''' menu)
*0 = m/s
*1 = mph
*2 = km/h
*3 = kts
These are the labels that Cumulus applies on its screens and web pages, most weather stations work in one unit (e.g. dm/s for Fine Offset) and so the values are converted to any of the 4 listed during processing
|-
|PressureUnit=0
|[[Pressure_Measurement]] unit used by Cumulus (as selected in the Units block of Station settings screen within '''Configuration''' menu)
*0 = mb
*1 = hPa
*2 = in
These are the labels that Cumulus applies on its screens and web pages, most weather stations work in one unit (e.g. hPa for Fine Offset) and so the values are converted to any of the 3 listed during processing
|-
|RainUnit=0
|[[Rain_measurement]] unit used by Cumulus (as selected in the Units block of Station settings screen within '''Configuration''' menu)
*0 = mm
*1 = in
These are the labels that Cumulus applies on its screens and web pages, most weather stations work in one unit (e.g. dm for Fine Offset) and so the values are converted to either of the 2 listed during processing
|-
|TempUnit=0
|[[Temperature_(and_humidity)_measurement#Temperature_Scales|Temperature measurement unit]] used by Cumulus (as selected in the Units block of Station settings screen within '''Configuration''' menu)
*0 = Celsius
*1 = Fahrenheit
These are the labels that Cumulus applies on its screens and web pages, most weather stations work in one unit (e.g. for Fine Offset a positive integer (a 12 bit value) that uses 0 at -40 degrees Celsius/Fahrenheit and 500 at 10 degrees Celsius/50 degrees Fahrenheit; i.e. you get the actual temperature in Celsius by subtracting 400 and dividing by 10) and so the values are converted to either of the 2 listed during processing
|-
|LocName=
|Location Name (as entered on the Station settings screen within '''Configuration''' menu) - used for title of tab in browser and main heading on each standard web page
|-
|LocDesc=
|Location Description (as entered on the Station settings Screen within '''Configuration''' menu) - inserted after 'Welcome to ' on 'Now' web page.
|-
|StartDate=13/08/2009
|This parameter is automatically inserted into cumulus.ini and given a value when Cumulus is first run. By default this will be set to the date of initial installation of the Cumulus application. See [[FAQ#I_have_inserted_pre-Cumulus_data_making_.27Records_began_on.27_date_wrong]]
|-
|CreateWxnowTxt=0
|This parameter (attribute=value) is added directly to the file in the [station] section, it does not appear on a configuration screen.
*0= turn off creation of wxnow.txt file (stored in main Cumulus folder)
*1= (default) create wxnow.txt file (an alternative way to get data to CWOP/APRS)
|-
|ListWebTags=0
|This parameter (attribute=value) is added directly to the file in the [station] section, it does not appear on a configuration screen.
*0= (default) turn off creation of WebTags.txt file (stored in main Cumulus folder)
*1= create WebTags.txt file when Cumulus is restarted (contains an unordered list of all the web tags Cumulus can recognise)
|-
|LastLoggerDownload=13/08/2008 12:48:52
|The date/time of the last down load from your weather station '''(note: no longer used, so only present if you used an earlier Cumulus version)'''; see [[Webtags#Miscellaneous|
<#LastDataReadT>]] for similar functionality
|-
|RainSeasonStart=1
|Selected in the Station Configuration Screen Settings block. The month (1 to 12) of the year that is used as the start of the annual 'rain season'. Default = 1 meaning January.
|-
|YTD[[FAQ#My_monthly_and.2For_annual_rainfall_totals_are_wrong|rain]]=0
|Selected in the Station Configuration Screen Settings block. Year to date correction if starting part way through rainfall year (see previous parameter). Value is entered in your current [[Rain_measurement]] units. Default is 0.
|-
|YTDrainyear=0
|Selected in the Station Configuration Screen Settings block. The year for which the previous parameter (YTDrain) is to be applied. Default is 0 meaning not applied to any year.
|-
|RainDayThreshold=-1
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. The threshold value which the daily rainfall has to equal or exceed for the day to be considered a 'rain day'. Default -1 = 0.2mm or 0.01in. Value is entered in your current [[Rain_measurement]] units.
|-
|NoFlashWetDryDayRecords=1
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. When set to 1 stops new Longest Wet/Dry Period records being 'flashed'
|-
|UseCumulusForecast=0
|From the Station Configuration Screen Forecast block, if selected Cumulus will generate a simple weather Zambretti forecast, if your station does not supply a forecast, or as an alternative to the one supplied by your station. See the [[Forecast webtag]] for more information. See next parameter for interval between forecast updates.
*0 = Disabled (default)
*1 = Enabled
|-
|HourlyForecast=0
|From the Station Configuration Screen Forecast block 'update hourly' parameter, applies only if Cumulus is set (see previous parameter) to generate a forecast (see [[FAQ#My_forecast_says_.22Not_available.22]]),
*0 = Disabled, (default) Cumulus will use Zambretti Forecaster every time it updates the web pages.
*1 = Enabled, this setting causes the forecast to be updated only once an hour (on the hour).
|-
|UseCumulusPresstrendstr=0
|Set in the Station Configuration Screen Settings block. If selected Cumulus will generate the name for the current pressure trend, e.g. "Falling", "Rising quickly" etc, instead of the one supplied by your station. The names used are those in the UK Shipping Forecast. Note that some stations do not supply this anyway, so setting this has no effect (Cumulus always generates the names for those stations).
*0 = Disabled
*1 = Enabled

|FCPressureThreshold=0.1
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. It specifies the threshold (in mb per hour averaged over 3-hour period) for a pressure change to count as rising or falling rather than steady when determining the Zambretti forecast. The default is 0.1 mb/hr averaged over the previous three hours.
|-
|FCpressinMB=1
|Forecast pressure unit as selected in the '''Forecast''' block in the bottom right of ''Station'' settings screen off '''Configuration''' menu. The units you use here are not related to the units you use for pressure (PressureUnit=x parameter earlier) in Cumulus; the option is given here simply as a convenience for the next two parameters.

|-
|RTdisconnectcount=N
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. By default, the 'realtime' ftp connection stays connected. You can make it disconnect periodically by adding an Option to periodically disconnect the realtime FTP connection, the theory being that it will not get stuck if the server dies, and will keep trying to reconnect.
N must be a positive integer. For example set N to '60'; it represents the number of realtime ftp uploads between disconnections - so 60 would give an hour if 1 minute realtime interval selected.
|-
|Logging=1
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. Add to cumulus.ini [Station] section to have Cumulus start with [[debug]] logging on

|UVdecimals=0
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.
UV values are now displayed and logged as whole numbers by default. You can change this by adding this entry specifying the number of decimal places. (added 1.9.3 build 1038)
*0 = Integer Values (default)
*n = Number of decimal places e.g. 1

A lot of extra settings were added to the file, but not added to the configuration screens. Documenting these was particularly difficult as only some got mentioned in release announcements, so the others were hard to discover, and allowed values were not always clear.
==== Davis family specific: ====
| Each time a beta version of Cumulus 1 was available, any parameters specific to that beta appeared in [[Cumulus.ini_(Beta)]], and only moved to the main page when that beta finished, and became the main release.
"The DLL" is a Windows Dynamic Link Library supplied by Davis for third parties to use when writing software for Davis stations.
| The same beta page, [[Cumulus.ini_(Beta)]], was briefly used for Cumulus 2.
| Finally, that beta page, [[Cumulus.ini_(Beta)]], was used for all the changes in Cumulus 3 (the MX beta):
It handles fetching data from the console, and does all kinds of useful things like converting the data into the units you require.
*Some of the parameters for Cumulus 1 were not used by MX beta
*Some of the parameters for Cumulus 1 were used by MX beta
*Beta MX only added 3 new parameters


This was the position when Steve Loft ceased his involvement with Cumulus. This page contained all parameters used for Cumulus 1, some of these were used by MX beta too.
Cumulus 1.9.x and Cumulus MX should both support these settings, check with release notes for your version and previous versions.

|DavisRainCollectorModel=X
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. (Available from Build 1096 of version 1.9.4)
Option to specify rain collector model for Davis stations for situations where the Davis DLL is unable to read it from station, and your rain figures in Cumulus are incorrect as a result (can happen when using Virtual VP, for example).
Value X is an integer from 0 to 5 with the following meanings:
*0 = 0.1 inch
*1 = 0.01 inch
*2 = 0.2 mm
*3 = 1 mm
*4 = 'other' inch
*5 = 'other' mm
Davis have not documented what calculations the DLL does for options 4 and 5. If this line is not included in '''cumulus.ini''' the DLL will use whatever type the station tells it to use
|-
|ForceVPBarUpdate=0
|Set this in the Station Configuration Screen '''Settings''' block. Select to force the Vantage Pro (and Pro2) barometer to update once a minute instead of the default 15 minutes. Note that you may not need this, more recent stations already update every minute
*0 = Disabled
*1 = Enabled
|-
|SyncDavisClock=0
|Set this in the Station Configuration Screen '''Settings''' block where called '''Synchronize station clock'''.
When set, at Cumulus start-up and at 04:00 each day, Cumulus will set the Davis VP/VP2 clock to within a minute of the same time as the PC. (From build 3015 for MX).
*0 = Disabled, default (as deselected on the Station Configuration Screen)
*1 = Enabled, ensures that when Cumulus asks the station for data since time X, both recognise X!
|-
|ClockSettingHour=4
|Configuration file only setting, controls what hour of the day the SyncDavisClock activity will take place if it is enabled.
*4 = 04:00 (default value)
*0-23 = 00:00 to 23:00
|-
|VP2ConnectionType=1
|Weather station connection type that is selected in the ''Station'' Configuration Screen '''Davis type''' block
*0 = serial (see next parameter to specify COM port)
*(1 = usb - setting no longer available on screen, remains as default in cumulus.ini for those not using a Davis)
*2 = TCP/IP (see later parameters to specify ports)
Default is type 1, i.e. neither option on screen selected, so if you use a Davis you must select either serial or TCP/IP..
|-
|Port=0
|Set this in the Station Configuration Screen '''Serial Port''' block.
Identifies COM Port used if Davis type is serial. Default is 0.
|-
|VP2TCPPort=22222
|Set this in the Station Configuration Screen '''Davis TCP/IP Settings''' block.
Comunications port used if VP type has TCP/IP selected. Default is 2222
|-
|VP2IPAddr=0.0.0.0
|Set this in the Station Configuration Screen '''Davis TCP/IP Settings''' block.
Weather station IP address if VP type has TCP/IP selected. Default is 0.0.0.0
|-
|VP2SleepInterval=500
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.
This is the period which Cumulus waits between reads of the data from Davis stations, the value is in milliseconds. The default is 500 ms; if you suspect that data is being missed, you could try reducing this figure. For VirtualVP users, tests revealed that VP2SleepInterval = 1100 seems to work the best. It updates every two seconds with few exceptions. See note in ''readme.txt'' about VP2SleepInterval - in v1.9.3 release it is around line 50. Related FAQ: [[FAQ#My_Davis_station_shows_a_higher_maximum_wind_speed_than_Cumulus]]
|-
|VPClosedownTime=x
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. x is the number of seconds after the start of the re-connect attempts that you want the program to close itself (added v.1.8.5 b.726).
|-
|VP2PeriodicDisconnectInterval=0
|Set this in the Station Configuration Screen '''Settings''' block with the ''Discon period'' value. Causes Cumulus to disconnect for the specified number of seconds, once a minute, on the minute (or as close as possible) to allow the Weatherlink IP to connect to the Davis Weatherlink site. Set it to zero to disable, if you are not using the Weatherlink site.
|-
|DavisCalcAltPress=1
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. Davis stations calculate Sea Level Pressure from Station Pressure using a formula based on several parameters such as temperature, humidity, etc, rather than just using altitude as most other stations. CWOP require 'Altimeter Pressure' to be uploaded, i.e. a value calculated simply using altitude.


The beta page contained some Cumulus 1 beta parameters that were still under development and the parameters that were only used by MX.
'''Note for MX''', use of the LOOP2 (see [[Cumulus.ini_(Beta)#Section:_Station| here]]) means s.l.p. can be obtained from the Davis station.

'''The following note applies to Cumulus 1.x.x:''' The station does not provide this value directly, nor the station pressure, so Cumulus 1.x.x has to read some extra data once a minute in order to do the calculation. This can take several seconds, so it means that a 'normal' data reading may be missed.

If you don't use CWOP, or you are happy for Cumulus to send Sea-Level pressure to CWOP (the difference is small unless you are at high altitude), set this value to 0.
Cumulus will then use the Sea-Level Pressure value instead of the Cumulus calculated Altimeter Pressure.
*0 = Disabled
*1 = Enabled (default)
|-
|LogExtraSensors=0
|This is set in the '''Settings''' block on the Station settings screen off the configuration menu. Set this to 1 if you have additional sensors (e.g. a Davis Leaf Wetness probe) to make Cumulus read, display, and log the readings from the sensors. You don't select this for Solar/UV sensors.
|-
|RestartIfDataStops=0
|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.
Davis stations can use this option explained in the [[#La_Crosse_specific:|La Crosse]] table if Cumulus sometimes fails to read information from the logger. As it says in the help, it may not fix the connection problem, but at least it stops Cumulus logging, so once you have fixed the problem it will download the missing data when you start it up again.

== Mark Crossley era==
====Introduced for problems with Fine Offset family:====
*These parameters were introduced for Cumulus to cope with Fine Offset stations and their clones, but a few of the parameters below may be found to be useful more widely.
*Some parameters are set on screens, other attributes do not appear in the '''cumulus.ini''' file unless they are added using an external editor, but the values still have a recommended default value as explained below.


* Cumulus.ini content has changed drastically, and therefore the documentation page called "Cumulus.ini" has also had to change drastically
{| class="wikitable" border="1"
* There was a period when it was possible for one page to document both the legacy Cumulus 1.9.4 and all MX releases, but that has long gone.
|-
!style="width:150px" | Parameter Line Entry
!style="width:600px" | Function
|-
|style="background:lightgray;"|[Station]
|style="background:lightgray;"|Section name - the following parameters relate to the station configuration.
|-
|RestartIfUnplugged=0
|This is set in the settings frame on the Station settings screen off the configuration menu.
*0 = Disabled, default i.e. deselected on the Station Configuration Screen
*1 = Enabled, Cumulus will restart if it detects that a Fine Offset station is unplugged. '''Note:''' Unless the station has been manually plugged in again, a Cumulus restart has no benefit; normally the station should be checked to be plugged in before Cumulus is ever started and the station then left plugged in.

|-
|SyncFOReads=0
|This is set in the settings frame on the Station settings screen off the configuration menu.
*0 = Synchronisation disabled, default (Cumulus reads the memory without taking into account when memory is being updated)
*1 = Re-synchronizes once each day, to avoid reading memory at time of memory update
A Fine Offset station will be writing to its memory every 48 or 60 seconds (depending on model); Cumulus can attempt once a day to identify when this update of memory occurs, and thereafter try not to read the memory at update time, by using what is called a synchronisation mode of operation. See next parameter.

|-
|FOReadAvoidPeriod=3
|Add this line to cumulus.ini [Station] section if you wish to change the default, this parameter used to fine-tune the previous parameter.

*3 = default value
Sets the interval (in seconds) during each 48 (or 60 for some models) second of station logging period when Cumulus will avoid reading the station data to try and minimise lock ups. If the clock drifts more than this value in 24 hours, then Cumulus may cause the station to lock up when reading the data. The actual station clock drift gets logged to the diags file when the re-synchronise (see last parameter) takes place, this will give an idea of whether it would be useful to adjust this setting.

|-
|ReportLostSensorContact=0
|Add this line to cumulus.ini [Station] section
*0 = reporting off
*1 = reporting on (default)
Option to turn off reporting of 'lost sensor contact' for Fine Offset stations. (added Cumulus 1.9.4 b.1070)

|-
|EWdisablecheckinit=0
|Add this line to cumulus.ini [Station] section if application gets stuck when Cumulus starts up connected to a Fine Offset (clone) station (added Cumulus version 1.9.2, build 1011).
*0 = Disabled, default, it checks the first two bytes of the Fine Offset station's memory.
*1 = Ignores part of memory (see [[FAQ#When_I_start_Cumulus.2C_I_get_the_error_message_.22The_station_is_not_initialised.22]]).


|-
|EWduplicatecheck=0
|Add this line to cumulus.ini [Station] section if application gets stuck in the download stage.
Introduced in version 1.8.5 (b.630) to deal with certain bytes being given the same value in first and second line.
*0 = Disabled, default, Cumulus accepts all bytes from the Fine Offset station's memory.
*1 = Ignores part of memory (see [http://sandaysoft.com/forum/viewtopic.php?f=13&t=393 this forum thread]).
For example one problem is that "55 AA" repeats at the start of the second line of data. Those bytes are only supposed to appear at the start of the first line (or so I am told).

|-
|EWpressureoffset=x.y
|Add this line to cumulus.ini [Station] section
Got a pressure problem with a Fine Offset station when the pressure 'offset' that Cumulus reads is garbage, so Cumulus just uses zero?
Tell Cumulus what offset to use, by using an external text editor to insert this parameter where x.y is the difference between your station (absolute) and sea-level (relative) pressures, in mb or hPa.

==== Spike Removal ====
* 7 of the 10 spike removal parameters listed below are adjusted in the frame at the bottom of the ''Calibration'' screen, off '''Configuration''' menu, they have a prefix of EW because they were introduced for dealing with problems seen in the Fine Offset family; the corrections are only applied when Cumulus is reading directly from the station at a very frequent interval, spike removal does not apply when Cumulus is re-started and is transferring observations from the station logger to the Cumulus monthly log.
*The other 3 spike removal parameters have to be entered directly in cumulus.ini, none of these ones can be set on the 'calibration' screen.
*As Cumulus does not check station type before applying any of these settings, ensure for Davis stations (these do not have spike problems) the spike removal filters are set to the defaults shown below.
*However, spike removal correction may be implemented for La Crosse stations, they can have problems with their PC interface, using the same EW filter settings listed below.

|EWMaxRainTipDiff=30
|Add this line to cumulus.ini [Station] section
Cumulus (1 and MX) has a configurable threshold for the maximum feasible amount of rain between updates (i.e. within 48-seconds on Fine Offset stations without solar, 60 seconds on those measuring solar), set in units of count of tips.
Default=30 tips, as each tip represents 0.3mm this is equivalent to 9 mm or just over a third of an inch in 48 seconds.
This setting affects rain rate, rain last hour, rain so far today (and what is recorded in today.ini/dayfile.txt), but does not affect the web tag <#r24hour>.
|-
|EWmaxHourlyRain=999
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu.
An hourly rain count 'spike removal' filter for weather stations that do not supply this figure so Cumulus has to calculate it.
Any ''changes in calculated value'', between one calculation and the next, greater than the value specified here will be ignored by Cumulus when it calculates the hourly rain total.
Cumulus ignores this parameter if the weather station directly supplies this figure to Cumulus. '''999''' is the default indicating no spike removal required.

|-
|EWmaxRainRate=999
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu.
A rain rate 'spike removal' filter, ''changes in calculated value'', between one calculation and the next, greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus when it calculates the rain rate.
Cumulus ignores this parameter for other makes of weather station (they supply a rain rate to Cumulus). The default value of '''999''' also effectively makes Cumulus ignore spike removal.

|-
|EWgustdiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A wind gust 'spike removal' filter, ''changes in calculated value'' between one calculation and the next, greater than the value (always metres per second) specified here (with a default of '''999.0''') will be ignored by Cumulus.

|-
|EWwinddiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu.. A wind speed 'spike removal' filter, ''changes in calculated value'' between one calculation and the next greater than the value (always metres per second) specified here (with a default of '''999.0''') will be ignored by Cumulus

|-
|EWpressurediff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A pressure change 'spike removal' filter, ''changes in read value'', from one reading to the next, off any station greater than the value (always mb) specified here (with a default of '''999.0''') will be ignored by Cumulus

|-
|EWminpressureMB=900
|Add this line to cumulus.ini [Station] section
Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millibars)

|-
|EWmaxpressureMB=1200
|Add this line to cumulus.ini [Station] section
Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millibars).

|-
|EWTempdiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A temperature change 'spike removal' filter.
Replace default of 999.0 with the maximum difference in degrees Celsius (the units Cumulus uses for all calculations regardless of what you select for display) you are prepared to accept between successive data readings.

|-
|EWhumiditydiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A humidity change 'spike removal' filter, ''changes in read value'' from any station greater than the value (as %) specified here (with a default of '''999.0''') will be ignored by Cumulus.

'''Requiring Cumulus to read Easyweather.dat instead of a station directly perhaps for Stations not recognised by Cumulus'''
*Stations not recognised by Cumulus ''may'' be set to create an [[EasyWeather_Format#Usage_of_easyweather.dat_fields_for_Cumulus_input_of_latest_record: |EasyWeather_Format]] file. For these the first two (or three) parameters below are mandatory.

'''Note:''' This approach is viewed as outdated, it was used if obsolete EasyWeather software version 6.2, or earlier, was running at same time as Cumulus software, both ran all the time, and Cumulus was required to simply process the latest record on the database, at the interval set in previous parameter, without all the additional processing Cumulus is able to do if it is reading directly from the console very frequently.
*(attribute and equals sign, but no value)= Default (Station '''Type''' ''not'' set to 4). '''Note:''' This is the default when Cumulus is operating normally.
*(attribute and equals sign, but no value)= Default (Station '''Type''' is set to 4). '''Note:''' If you want to run Cumulus without an attached weather station (because your station has a fault or because you have a second PC), it is possible to run Cumulus with station '''Type=4''' but with the default of no file specified in this parameter. The full Cumulus directory structure and its files including those in the ''data'' sub-directory are needed (kept from when your station was working or copied from the PC with the station). Although only the old observations can be accessed, (no new ones are being added), this does allow analysis of the old observations via all Cumulus features such as '''View''' ''This period'' and '''View''' ''Select-A-Graph''. See [[FAQ#Cumulus_isn.27t_performing_periodic_tasks.2C_like_data_logging_or_web_uploads|FAQ here]] for reduced functionality using Cumulus in this way.
|-
|LogExtraSensors=0
|This is set in the settings frame on the Station settings screen off the configuration menu.
*0 = Disabled (default)
*1 = Enabled; Use if you a) have Fine Offset models (generally those [[EasyWeather_Format#Note_on_Models|models 3xyz]]) with Solar/UV sensors, and b) '''Type=4''' set in that parameter (see top of [station] section), and c) '''EWFile='''''path'''''/EasyWeatherPlus.dat''' set in previous parameter. Only relevant if '''all these''' conditions met.
'''Note:''' Cumulus uses this parameter to determine where to find each observation (e.g. outside temperature, wind speed, humidity etc.) in the latest file record. If you set this parameter wrong, Cumulus will assign what it finds in various field locations wrongly and therefore it is highly likely that temperatures, wind speeds and everything else will appear to have many rogue values in Cumulus but look okay on the weather station console display.

This parameter is also used for other makes of weather station, see the relevant section for your make as the parameter is used differently.

|-
|style="background:lightgray;"|[Station]
|style="background:lightgray;"|Section name - the following parameters relate to the station configuration.
|-
|ImetWaitTime=200
|This parameter (attribute=value) if you need to change it from its '''default of 200 ms''' is added directly to the file, it does not appear on a configuration screen.
Specifies the time in milliseconds that Cumulus allows for a response from an Instromet station. If you are having problems with reading from an Instromet station, try inserting this line into the ''Station'' section using a value of 500. According to the specification, 500 ms is the absolute maximum time that the station should take to respond to any command.
|-
|SyncDavisClock=0
|Set this in the Station Configuration Screen Settings block where called '''Synchronize station clock'''. Note despite the name of the parameter within 'Cumulus.ini', this does apply to Instromet stations.
When set, at Cumulus start-up and at 04:00 each day, Cumulus will set the Davis VP/VP2 clock to within a minute of the same time as the PC
*0 = Disabled, default as deselected on the Station Configuration Screen
*1 = Enabled, ensures that when Cumulus asks the station for data since time X, both recognise X!
|-
|LogExtraSensors=0
|This is set in the settings frame on the Station settings screen off the configuration menu by the '''Extra Sensors''' selection.
*0=Disabled (default)
*1= Enabled - Used for optional Sunshine hours or extra temperature sensors on Instromet stations.
(Note this attribute appears in [[#Davis_family_specific|Davis family]], [[#Oregon_Scientific_specific:|Oregon Scientific specific]] and [[#Introduced_for_problems_with_Fine_Offset_family:|Fine Offset family]] tables above with different usage explanations).

!style="width:150px" | Parameter Line Entry
!style="width:600px" | Function
|-
|style="background:lightgray;"|[Offsets]
|style="background:lightgray;"|Section Name - the following 'attribute=value' parameters are the adjustment factors for your specific sensors
|-
|PressOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter, used for formula: Cumulus pressure = Measured Pressure + 'Offset_Value'
|-
|TempOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter, used for quadratic formula shown below
|-
|TempMult=1
|First order multiplier by which measured outdoor Temperature is to be corrected (default=1).
For formula see next item.
|-
|TempMult2=0.0
|This line needs to be added in the [Offsets] section of the Cumulus.ini, if it is omitted default multiplier is 0.0.
"Second order" multiplier by which measured outdoor Temperature is to be corrected, this means that the logged reading can be (TempMult2 * measured-temp * measured_temp) + (TempMult * measured_temp) + TempOffset
|-
|HumOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus Humidity = Measured Humidity + 'Offset_Value'
|-
|WindDirOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus Wind Bearing = Measured Wind Bearing + 'Offset_Value'
|-
|InTempOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus Indoor Temperature = Measured Indoor Temperature + 'Offset_Value'
|-
|WindSpeedMult=1
|Multiplier by which measured Average [[Wind_measurement#Wind_Speed|Wind Speed]] is to be corrected (default=1).

e.g. Officially in UK the wind speed is measured with sensors at 10m above ground level. If your sensor is not at 10m AGL then a correction multiplier should be applied using the following formula ''V10/Vh = 1/(0.233 + 0.656*log10(h+4.75))'' where "h" is your sensor height in meters so if your anemometer is 5m off the ground, V10/Vh comes out at 1.134
|-
|WindGustMult=1
|Multiplier by which measured [[Wind_measurement#Wind_Speed|Wind Gust]] Speed is to be corrected (default=1).
|-
|HumMult=1
|Multiplier by which measured Humidity is to be corrected (default=1).
|-
|RainMult=1
|Multiplier by which measured Rainfall (and therefore rainfall rate too) is to be corrected (default=1).
|-
|UVOffset=Offset_Value
|Default 'Offset_Value' is 0 in this parameter used for formula: Cumulus UV level = Measured UV level + 'Offset_Value'
|-
|UVMult=1

* Until MX release 3.4.6, people using MX needed to refer to the page now called [[Cumulus.ini_(Cumulus_1)]], which was called "Cumulus.ini" at the time, and the beta page, [[Cumulus.ini_(Beta)]], as MX still used most of the parameters that the legacy software used and just a few new parameters. The latter still contained information from the last Cumulus 1 beta relating to Proxies section of Cumulus.ini, as that had not been finalised.
|-
* When Mark Crossley brought MX out of beta, he started adding new features to MX:
|GradientMiddle=16777215
** Some features represented functionality in the legacy software that MX had lacked, these used parameters that had been used for the legacy software
** For other new features, like interfaces with new weather station types and new sensors, he created new parameters, and the beta page began to rival the legacy page in the number of parameters it covered
* The information about MX on the beta page stayed there until April 2020
|
|
* Release 3.6.0 was when the functionality of MX first started to exceed the functionality of the legacy software
|-
* Between April and June 2020, information on the beta page was slowly moved across to the main page, it took some time as it needed to be verified because as MX developed configuration file content was changing
|GradientEnd=8421504
* Suddenly, a lot of people were migrating from the legacy software to MX
* To help people migrating, from June 2020, all settings (for both the legacy software and MX) were covered on a single "Cumulus.ini" page
* As people migrated, they could see on that single page clearly which parameters in their '''Cumulus.ini''' file were still valid, and what new parameters were needed when they migrated
* For those using MX, the page was recording the new parameters that were being added to the file as MX developed
* Now the history of all the changes at that time can be viewed on this page, as this was originally the page that once held that combined information.
|
|
* From release 3.8.0, the pace of change in MX was so fast, and the contributors to the Wiki so few, the page then called "Cumulus.ini" (with its previous content) stopped being maintained.
|-
*# The main problem was somebody needed to do a lot of research, and devote a lot of time, to track what the developer was changing.
|SAGintempcolour=32768
*# There was a second problem, it was clear that it was too complicated to use the same page to describe configuration for the legacy software, older MX releases, and the latest MX release
|(Select-A-Graph)
* Consequently, the "Cumulus.ini" page had to change, and the first move meant accepting MX and the legacy software could not be documented any more on the same page
|-
** A new page was created [[Cumulus.ini_(Cumulus_1)]], and all the information specific to the legacy software was split off from this page
|SAGouttempcolour=255
* This still left the problem that this page, at that time called "Cumulus.ini", had information that related to a release that had been superseded
|
** Another new page was created, [[Cumulus.ini (MX_3.0.0_to_3.7.0)]], and all the MX information was moved there.
|-
* Finally, this old "Cumulus.ini" paqe, with the attached history, but without any parameter information in the main page, was renamed to its current name, so it has preserved the history of the old page that had been split into two new pages, neither of which had the past history

* At release 3.10.0, the settings pages in the admin interface were given a significant makeover, and huge numbers of new settings were created, while many others became redundant
* It was clear the old [[Cumulus.ini (MX_3.0.0_to_3.7.0)|MX "Cumulus.ini"]] page was badly designed for the way 3.10.0 operated
* That old page was already out of date as it had not been updated for 3.8.0 changes
* It became obvious it was easier to start a new page that would would be based around 3.10.0 MX release, but would incorporate changes from 3.8.0 onwards, and would ignore anything that was now redundant
* The other change was a redesign of the page, so it focussed on explaining how to change the settings using the admin interface, rather than just documenting what each parameter in the file was used for
|
* As MX was developed, its settings pages were being redesigned, and so where you changed particular parameters in the file was modified making the documentation that already existed obsolete for people using latest release, but still valid for people who were using an older release.
* As release 3.12.0 was planned to add many, many more parameters to the Cumulus.ini file, and the Settings pages get another redesign, it was decided the documenting of the changes in 3.8.0, 3.9.2, and 3.10.0 would be delayed until it became clearer what might change in 3.12.0
* The new [[Cumulus.ini]] page to cover all these recent releases was created in June 2021, a year after the last big change to a page with that name.

|-
|SunThreshold=75
|If you have a solar sensor: Cumulus tries to determine whether the sun is shining by determining whether the current solar radiation value is above a certain percentage of the current theoretical maximum. The value you supply here is used as that percentage. The default value is 75%.
|-
|RStransfactor=0.8
|Cumulus uses the Ryan-Stolzenbach formula to determine the current theoretical maximum solar radiation at your location at the current moment in time. This formula has a factor to allow for the transmission of the radiation through the atmosphere; the default is 0.80.
|-
|SolarMinimum=0
|This setting allows you to specify a minimum solar radiation value which needs to be reached before it can be considered to be sunny. Note that this setting does not replace the calculation using the current theoretical maximum, it specifies an additional condition which has to be met. This setting therefore allows you to cater for the periods at the beginning and end of the day when the theoretical maximum is very low.

|LuxToWM2=0.0079
|Edit cumulus.ini to add this parameter if you have a Fine Offset station with a solar detector. These supply 'Lux' values rather than 'W/m2' values that Davis stations supply.

Latest revision as of 07:20, 15 June 2021

This page has been renamed from "Cumulus.ini" to preserve the early history of that page.

The information that was on this old Cumulus.ini page has been moved into separate pages for Cumulus 1, MX early releases, and MX latest releases.

History of this page

This page has proved the most complicated of all those in the Wiki to maintain:

  1. Settings change extremely often
    • Therefore it is a lot of effort to keep the documentation up to date
    • It is obviously easiest if an update is made here as soon as the settings change, sometimes that happens (perhaps by developer doing an update here)
  2. The design of configuration menus/screens/pages to edit the settings periodically changes
    • This means information about how to change settings often depends upon which release someone is using
      • In turn that means, either Cumulus users of latest release, or those using an earlier release, will struggle with the documentation
  3. Developers often provide limited information about settings,
    • Sometimes new settings are mentioned in an answer in a forum post, and do not get mentioned as a change in release announcements
      • This means that finding accurate information to update this page requires an awful lot of research that is very time consuming

The above observations applied for the legacy software, when Cumulus 2, and then 3 (MX), came along the documentation was originally split. When MX started (in 2019 to early 2020) to try to replicate much of what Cumulus 1 offered, it made sense to reuse what was written on this page for Cumulus 1, instead of duplicating it on a second page.

Then from mid 2020 to early 2021, there was rapid development of MX by the new developer, and MX began to increasingly diverge more and more from the legacy configuration, this page reflected that by introducing sub-sections (Cumulus 1 only, MX only, and both). From early 2021 onwards that 3 sub-section design for this page failed because new MX releases began to diverge from earlier MX releases. In other words, parameters that had existed at an early MX release, were no longer used by later releases. It was possible, but increasingly more and more difficult, to track new parameters to add that were added at particular releases, so the documentation got more and more obsolete.

To sum up, it was impossible for this page to show information for the legacy software, for early MX releases, and for later MX releases. The response was to move off this page anaything not relevant to the latest MX release, and to restructure this page based on how MX settings are altered, rather than where a parameter appears in the file.


Steve Loft Era

The configuration file content relating to the legacy software (e.g. 1.9.4) has been moved to legacy page

Legacy Software 1.x.y releases Beta builds of legacy software Cumulus 2 alpha releases MX beta 3.0.0
This page was created for the legacy Cumulus 1 software (up to 1.9.4). If you look at the history tab of this page, user‎ Shamrockspider created this page at 12:55 on 27 August 2009 for the purpose of Documenting the cumulus.ini file content and its function.

Back in 2009, the file was fairly simple, and therefore documentating it was also fairly easy.

Some settings were in configuration screens, and the file was arranged so that those settings were stored under a heading that generally (not in every case, for historic reasons) reflected the screen name. Documenting these was comparitively easy, the setting could be found easily and its allowed values could be easily tested.

A lot of extra settings were added to the file, but not added to the configuration screens. Documenting these was particularly difficult as only some got mentioned in release announcements, so the others were hard to discover, and allowed values were not always clear.

Each time a beta version of Cumulus 1 was available, any parameters specific to that beta appeared in Cumulus.ini_(Beta), and only moved to the main page when that beta finished, and became the main release. The same beta page, Cumulus.ini_(Beta), was briefly used for Cumulus 2. Finally, that beta page, Cumulus.ini_(Beta), was used for all the changes in Cumulus 3 (the MX beta):
  • Some of the parameters for Cumulus 1 were not used by MX beta
  • Some of the parameters for Cumulus 1 were used by MX beta
  • Beta MX only added 3 new parameters

This was the position when Steve Loft ceased his involvement with Cumulus. This page contained all parameters used for Cumulus 1, some of these were used by MX beta too.

The beta page contained some Cumulus 1 beta parameters that were still under development and the parameters that were only used by MX.

Mark Crossley era

  • Cumulus.ini content has changed drastically, and therefore the documentation page called "Cumulus.ini" has also had to change drastically
  • There was a period when it was possible for one page to document both the legacy Cumulus 1.9.4 and all MX releases, but that has long gone.
MX beta releases 3.0.0 to MX release 3.4.6 MX releases 3.6.0 to 3.7.0 MX releases 3.8.0 to 3.9.7 MX releases 3.10.0 to 3.11.4 MX release 3.12.0 onwards
  • Until MX release 3.4.6, people using MX needed to refer to the page now called Cumulus.ini_(Cumulus_1), which was called "Cumulus.ini" at the time, and the beta page, Cumulus.ini_(Beta), as MX still used most of the parameters that the legacy software used and just a few new parameters. The latter still contained information from the last Cumulus 1 beta relating to Proxies section of Cumulus.ini, as that had not been finalised.
  • When Mark Crossley brought MX out of beta, he started adding new features to MX:
    • Some features represented functionality in the legacy software that MX had lacked, these used parameters that had been used for the legacy software
    • For other new features, like interfaces with new weather station types and new sensors, he created new parameters, and the beta page began to rival the legacy page in the number of parameters it covered
  • The information about MX on the beta page stayed there until April 2020
  • Release 3.6.0 was when the functionality of MX first started to exceed the functionality of the legacy software
  • Between April and June 2020, information on the beta page was slowly moved across to the main page, it took some time as it needed to be verified because as MX developed configuration file content was changing
  • Suddenly, a lot of people were migrating from the legacy software to MX
  • To help people migrating, from June 2020, all settings (for both the legacy software and MX) were covered on a single "Cumulus.ini" page
  • As people migrated, they could see on that single page clearly which parameters in their Cumulus.ini file were still valid, and what new parameters were needed when they migrated
  • For those using MX, the page was recording the new parameters that were being added to the file as MX developed
  • Now the history of all the changes at that time can be viewed on this page, as this was originally the page that once held that combined information.
  • From release 3.8.0, the pace of change in MX was so fast, and the contributors to the Wiki so few, the page then called "Cumulus.ini" (with its previous content) stopped being maintained.
    1. The main problem was somebody needed to do a lot of research, and devote a lot of time, to track what the developer was changing.
    2. There was a second problem, it was clear that it was too complicated to use the same page to describe configuration for the legacy software, older MX releases, and the latest MX release
  • Consequently, the "Cumulus.ini" page had to change, and the first move meant accepting MX and the legacy software could not be documented any more on the same page
    • A new page was created Cumulus.ini_(Cumulus_1), and all the information specific to the legacy software was split off from this page
  • This still left the problem that this page, at that time called "Cumulus.ini", had information that related to a release that had been superseded
  • Finally, this old "Cumulus.ini" paqe, with the attached history, but without any parameter information in the main page, was renamed to its current name, so it has preserved the history of the old page that had been split into two new pages, neither of which had the past history
  • At release 3.10.0, the settings pages in the admin interface were given a significant makeover, and huge numbers of new settings were created, while many others became redundant
  • It was clear the old MX "Cumulus.ini" page was badly designed for the way 3.10.0 operated
  • That old page was already out of date as it had not been updated for 3.8.0 changes
  • It became obvious it was easier to start a new page that would would be based around 3.10.0 MX release, but would incorporate changes from 3.8.0 onwards, and would ignore anything that was now redundant
  • The other change was a redesign of the page, so it focussed on explaining how to change the settings using the admin interface, rather than just documenting what each parameter in the file was used for
  • As MX was developed, its settings pages were being redesigned, and so where you changed particular parameters in the file was modified making the documentation that already existed obsolete for people using latest release, but still valid for people who were using an older release.
  • As release 3.12.0 was planned to add many, many more parameters to the Cumulus.ini file, and the Settings pages get another redesign, it was decided the documenting of the changes in 3.8.0, 3.9.2, and 3.10.0 would be delayed until it became clearer what might change in 3.12.0
  • The new Cumulus.ini page to cover all these recent releases was created in June 2021, a year after the last big change to a page with that name.

Original content of this page

How this page used to be laid out, and why

For both Cumulus 1 and early MX releases, the content on this page was arranged assuming people were editing the file directly.

Therefore, the file was described by working through the sections on the file, and explaining the parameters that could go in each section.

For the longer sections, parameters might be split into separate tables to make it easier.

Before release 3.10.1, there were two types of parameters in Cumulus.ini.

  1. "read-only" settings were made directly in the "Cumulus.ini" file, there was no way to adjust these parameters using the settings screens/pages
  2. "read-write" settings could be changed in two ways, either by editing the file with Cumulus stopped, or by finding the parameter on a setting screen (for MX, these are in admin interface).
You will see in the two pages split off from this page (Cumulus.ini_(Cumulus_1) and Cumulus.ini (MX_3.0.0_to_3.7.0)), how the parameters had to identify themselves as read-only or read-write.

Why has this original "Cumulus.ini" page been renamed, cleared of old content, and made historic?

  1. One big change in 3.10.1 is that (almost) all settings are now made via the Admin interface.
    • Therefore it makes no sense any more to organise this page how someone editing the file directly might want.
    • The replacement Cumulus.ini page is now organised by how you change settings in the admin interface (i.e. similar to how settings have been explained in MX_Administrative_Interface#Changing_Settings).
  2. Another change is that some of the settings that used to be made on the “Station Settings” page, are now made on different pages in that interface.
  3. Yet another change is that what you pick in some settings can affect what settings are shown later on the admin interface page.
    • You could say the settings pages have become intelligent.
    • For example, when you select a weather station type it ensures only parameters that relate to that weather station type are shown.
    • As another example, you can opt in or out of the default web site design, so that determines which parameters relating to web sites are shown.
