Cumulus MX Local API

There are two methods of calling the Cumulus MX local API (note the web tag names are case sensitive just like normal):

General API - HTTP GET

This provides a quick and simple method of getting data, you just provide the web tag names in the GET URL and MX returns a simple JSON string with the tag-name:tag-value pairs. The tags are always returned with the default format. You can specify a special parameter "rc" (which must be the first URL parameter) to apply the usual remove commas format to all the tags.

eg.

http://localhost:8998/api/tags/process.json?temp&hum&dew

or

http://localhost:8998/api/tags/process.json?rc&temp&hum&dew

Which will return the following format string in the body...

{"temp":"15.8","hum":"73","dew":"10.5"}

Note, ALL values are quoted as strings as it is difficult to know which are numeric and which are not.

General API - HTTP POST

The POST method allows you to put whatever text you like in the request body - and include any web tags plus formatting you wish. The string returned will be exactly the same text with the tags substituted with data. So you could send a simple comma separated list, or some JSON text, or XML, whatever.

eg.

http://localhost:8998/api/tags/process.txt

With a POST body text of..

<#time format="yy/MM/dd hh:mm:ss">,<#temp>,<#RecentFeelsLike d=1>

would return...

20/07/14 01:48:11,15.7,18.4

or

{
   "DateTime:"<#time format="yy/MM/dd hh:mm:ss">",
   "OutsideTemp":<#temp>,
   "FeelsLikeYest":<#RecentFeelsLike d=1>
}

would return...

{
   "DateTime:"20/07/14 01:50:56",
   "OutsideTemp":15.7,
   "FeelsLikeYest":18.4
}
