does emoncms accept http POST or does it only work with GET?
currently i am uploading data to emoncms with http GET like this:
https://hostname/api/post?apikey=TOKEN&json={var1:200.2,var2:200,var3:100}
i would prefer to do http POST like this:
https://hostname/api/post
then put the json data, including the apikey, into the actual http POST payload. i anticipate having some rather large chunks of json data (feeds from more than 50 circuits/sensors for each sample) and i do not want to run into URL length issues.
is this supported by emoncms?
where is the API definition for how to interact with the emoncms server?
Re: posting data to emoncms
Hello powermeister, although emoncms does not currently do this, it would be a relatively easy fix to make ti happen, if you go to Controllers/api_controller and switch the $_GET lines to $_POST. that should do it.
A beginning on the api description can be found here: http://openenergymonitor.org/emon/node/192
Re: posting data to emoncms
thanks for that.
in the api page, could you add a column that indicates when each api element (each row in the api tables) was implemented? that way we would have a reference for not only what is actually implemented, but also when each feature was implemented (so we'll have a better idea of when to upgrade) and a map of what the unimplemented features/calls will look like (so we can have discussions about them and possibly go off and implement them).
for example, instead of just these columns:
actions | external api | access | internal api
have these columns:
actions | access | external api | internal api | when implemented
the 'when implemented' column would have the release number (or even the git hashcode) when the row became available.

Thanks for all the suggestions, I will add these columns in
Re: posting data to emoncms
Hello
I have a problem , is that the Interfacing with the emoncms models and database via the emoncms API does not work .
the method client.println("emoncms/api/post?apikey=YOURAPIKEY&json={power:200.2}");
don't have any result .
what should I do ?
Re: posting data to emoncms
Hello maha
Are you using client.println() along with the reset of the Arduino Ethernet sketch?
Have you tried accessing the API from your internet browser?
Re: posting data to emoncms
Hello,
I would like to ask:
1) In order to send data to Emoncms I have to open the browser and use a command like e.g http://localhost/emoncms/input/post.json?node=1&csv=100,200,300???
Assuming I use Java to get values from my analyzers. The only way to send data is to call Browser from java with link "http://localhost/emoncms/input/post.json?node=1&csv=100,200,300" and then close the browser using java, or maybe I can import the data using an other method.
2)If I want to use The Led in dashboard (green for 1 and red for 0) for a variable, do I need to create a Feed for this variable? I don;t want to have a log but only show the real-time status (when i say real-time I mean the last value (0 or 1) that was sent to Emoncms).
3)In order to create a feed and log Day Energy I get from my analyzers Power Values and Total Energy Values.
The Total Energy Value is an incremental variable that never goes to zero.
Can I use only the Power Value with the Power to kWh/d process so that the EmonCMS can calculate the daily energy consumption/production?
I should use the Total Energy Value with the Wh increment to khw/d process or with kWh to kWh/d process in order to get daily energy consumption/production if Power Value alone is not enough?
Thank you
George
