[[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 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.


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 various external websites.


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 the parameters allowed within those sections may be a subset of those listed below.
# Settings change extremely often
= File Structure =
#* Therefore it is a lot of effort to keep the documentation up to date
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.
#* 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.
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.


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).
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).
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.
== Beta builds ==
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 annoucement 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 [[Cumul.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 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 Cumulus.ini. 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 situration.


==Steve Loft Era==
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.


<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>


''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.

== 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.

|The weather station model description - you choose what text appears for this on (from version 1.9) 'Display' settings screen within Configuration menu - the field is at the bottom left of that screen).
|-
|Port=0
|Com port in your computer which is connected to your weather station if connected via a serial port. Defaults to port 0.
|-

|-
|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 as entered in the Station Configuration Screen Location block. See Cumulus Help for that screen.
|-
|AltitudeInFeet=1
|Altitude measurement unit as set in the Station Configuration Screen Location block.
*0 = metres Above Sea Level
*1 = feet ASL
|-
|Humidity98Fix=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled (default)
*1 = Enabled, humidity displayed and recorded as 100% if your sensor registers a relative humidity of 98% or greater. Normally only useful for Oregon Scientific stations.
|-
|Wind10MinAverage=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled (default)
*1 = Enabled, Cumulus will calculate and display a 10-minute average wind speed instead of using the value supplied by the station.
|-
|CalculatedDP=0
|Selected in the Station Configuration Screen Settings block.
*0 = Disabled
*1 = Enabled, Cumulus will calculate the dew point instead of using the value supplied by the station. 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
|Add to cumulus.ini [Station] section to disable 'calculate [[Wind chill]] only if temperature less than 10&#176;C rule'.
*0 = Disabled, Cumulus will use wind speed to determine the wind chill ignoring the temperature criterion
*1 = Enabled (default), Cumulus will use both temperature and 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
|The temperature threshold is specified in the units that you use in Cumulus (see [[Heat/cold_degree_days_and_Chill_hours]])
|-
|ChillHourSeasonStart=10
|The season start figure is the calendar month number (1 to 12)

|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 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.
|-
|ConfirmClose=0
|Confirm 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, on the Station Configuration Screen, Cumulus will close if you suspend/standby/hibernate your computer. You should not select 'Confirm shutdown' 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 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.
*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.

|WindUnit=0
|[[Wind_measurement#Wind_Speed|Wind speed measurement unit]] Cumulus records in as selected in the Station Configuration Units block
*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 Cumulus records in (as selected in the Station Configuration Units block)
*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

|The date/time of the last down load from your weather station '''(note: no longer used)'''; see [[Webtags#Miscellaneous|
<#LastDataReadT>]] and [[Today.ini|Timestamp]]
|-
|YTD[[FAQ#My_monthly_and.2For_annual_rainfall_totals_are_wrong|rain]]=0
|Year to date correction if starting part way through year as entered in the Station Configuration Screen. Value is entered in your current [[Rain_measurement]] units. Default is 0.
|-
|YTDrainyear=0
|The year for which the YTDrain is to be applied. Default is 0 meaning not applied to any year.
|-
|UseDataLogger=1
|If selected, at start-up, Cumulus will download data from the stations data logger (if it has one) to catch up from the point where Cumulus was last shut down.
*0 = Disabled
*1 = Enabled (Default)
|-
|UseCumulusForecast=0
|From the Station Configuration Screen Forecast block, if selected Cumulus will generate a simple weather forecast, if your station does not supply one, or as an alternative to the one supplied by your station. See the [[Forecast webtag]] for more information.
*0 = Disabled (default)
*1 = Enabled
|-
|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
|-
|FCpressinMB=1
|Forecast pressure unit as selected in Station Configuration Forecast block
*0 = inches
*1 = mb
|-
|FClowpress=950
|Low Pressure extreme limit as entered in the Station Configuration Forecast block. Default is 950mb
|-
|FChighpress=1050
|High Pressure extreme limit as entered in the Station Configuration Forecast block. Default is 1050mb
|-
|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 10 minutes, 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
|-
|WarnMultiple=0
|Multiple Instances of Cumulus running on PC
*0 = Disabled, (default) Multiple instances allowed.
*1 = Enabled, prevents multiple instances of Cumulus from running. Requires a Cumulus restart to take effect.
|-
|CloudBaseInFeet=1
|Cloud base measurement unit
*0 = metres
*1 = feet (default)
|-
|RTdisconnectcount=N
|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
|Add to cumulus.ini [Station] section to have Cumulus start with [[debug]] logging on
|-
|AvgSpeedMinutes=N
|where N is the number of minutes over which Cumulus calculates its average speed, if you have Cumulus set to do this. Default = 10. If you selected 60, then Cumulus would calculate rolling 60-minute average wind speeds.
|-
|AvgBearingMinutes=N
|where 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. Default = 10.

|Add this entry to make Cumulus create (each time it is restarted) a file called webtags.txt that contains an unsorted list of all the webtags that Cumulus supports
|-
|RainSeasonStart=1
|The month of the year that is used as the start of the annual 'rain season'. Default = 1 = January.
|-
|RainDayThreshold=-1
|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
|When set to 1 stops new Longest Wet/Dry Period records being 'flashed'
|-
|UseSpeedForAvgCalc=0
|When enabled (=1) Cumulus will use the longer-term 'speed' values in the average speed calculation. The 'Use 10-min average wind speed' option must be selected for this option to have any effect.
|-
|HourlyForecast=0
|If Cumulus is set to generate a forecast, this setting (=1) causes the forecast to be updated only once an hour (on the hour).
|-
|RoundWindSpeed=0
|When set to 1, this setting causes wind speeds rounded to the nearest integer.
|-
|ErrorLogSpikeRemoval=0
|??keeps the number of messages in the error log window to a maximum of 256?
|-
|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
|-
|NoSensorCheck=1
|The option (for 'incomplete' stations) to disable the sensor check described in this [http://wiki.sandaysoft.com/a/FAQ#Cumulus_isn.27t_performing_periodic_tasks.2C_like_data_logging_or_web_uploads FAQ]
*0 = Sensor check enabled (default)
*1 = Sensor check disabled

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

|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
|When set, at start-up, Cumulus will set the Davis VP/VP2 clock to the same time as the PC
*0 = Disabled, default as deselected on the Station Configuration Screen
*1 = Enabled
|-
|VP2ConnectionType=0
|Weather station connection type as selected in the Station Configuration Screen VP type block
*0 = serial
*1 = usb
*2 = TCP/IP
|-
|VP2TCPPort=22222
|Set this in the Station Configuration Screen VP2 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 VP2 TCP/IP Settings block. Weather station IP address if VP type has TCP/IP selected. Default is 0.0.0.0
|-
|VP2SleepInterval=x
|where x is sleepinterval in milliseconds. See note in ''readme.txt'' about VP2SleepInterval - in current release it is around line 50. This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. See [[FAQ#My_Davis_station_shows_a_higher_maximum_wind_speed_than_Cumulus]]
This is the period which Cumulus waits between reads of the data from Davis stations. 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.
|-
|VPClosedownTime=x
|where 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). This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.
|-
|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
|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 station does not provide this value directly, nor the station pressure, so Cumulus 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.


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.
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 frame 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 need to select this for Solar/UV sensors.
|}


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.
====Introduced for problems with Fine Offset family:====
| 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.
*These parameters apply to Fine Offset stations and their clones, but a few may be more widely applicable
| The same beta page, [[Cumulus.ini_(Beta)]], was briefly used for Cumulus 2.
*Some parameters are set on screens, other attributes do not appear in the file unless they are added using an external editor, but the values still have a recommended default value as explained below.
| Finally, that beta page, [[Cumulus.ini_(Beta)]], was used for all the changes in Cumulus 3 (the MX beta):
*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.
*Some of the parameters for Cumulus 1 were not used by MX beta
*However, spike removal correction may be implemented for La Crosse stations using the EW filter settings below.
*Some of the parameters for Cumulus 1 were used by MX beta
*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 requiring the first two parameters below.
*Beta MX only added 3 new parameters

|WindSpeedMult=1
|Multiplier by which measured Average [[Wind_measurement#Wind_Speed|Wind Speed]] is to be corrected (default=1).


* Cumulus.ini content has changed drastically, and therefore the documentation page called "Cumulus.ini" has also had to change drastically
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

* 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
|WindRoseTransparency=50
* 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.
|WindGaugeAnimated=1
*# 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
|Animate the Wind Gauge pointer movement
* 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
*0 = Disabled,
** A new page was created [[Cumulus.ini_(Cumulus_1)]], and all the information specific to the legacy software was split off from this page
*1 = Enabled (default)
* 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.
|WindGaugeAnimationFactor=2
* 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
|This sets the speed of the wind gauge animation. Lower values correspond to a faster animation speed. Be careful not to set the animation too slow, particularly with stations which update frequently (e.g. Davis) as the animation will never catch up, and will use significant CPU time.

* 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.

For both [[Cumulus.ini_(Cumulus_1)|Cumulus 1]] and [[Cumulus.ini (MX_3.0.0_to_3.7.0)|early MX releases]], the content on this page was arranged assuming people were editing the file directly.

|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.

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.
  4. A final change is that some parameters are grouped as “Advanced”, so that novices can avoid those.
