I'm using a Brultech ECM-1240 to monitor my PV production and household energy use. I've got the ECM-1240 and btmon.py running on a Raspberry Pi. It's all set up and has been sending data to the Smart Energy Groups website for a couple of years. Now I'd like to try sending data for display on emoncms.org. How should I setup the config.cfg file for btmon? This is what I've tried, which seems to work, but I'm having trouble setting up some visualizations and widgets. Perhaps I have the oem_url wrong? Or am I missing some other key lines?
[openenergymonitor] oem_out = true oem_url=http://emoncms.org/input/post oem_token = xxxxxxxxxxxxx (Write API Key)
In emoncms.org, I've got a simple dashboard with a few realtime and rawdata visualizations working, but I cannot configure a multigraph - when I go to configure the multigraph, the "configure element" drop-down list is blank (see attached image). Also, I can create a Dial widget, but cannot get it show any values other than zero. Suggestions appreciated!
Re: Help setting up btmon.py to send to emoncms.org
The multigraph needs to be created in "Vis" -> "multighraph" first,
the "configure element" refers to the page element that will consist of a preconfigured multigraph from the list (mid = multigrapgh id), not configuring the multigraph itself.

Re: Help setting up btmon.py to send to emoncms.org
Thanks, pb66. I got the multigraph to work. But I still cannot get the Dial widget to work - it shows zero no matter how I configure it. I tried a Bar widget but it only shows "NaN".
Is there a "getting started" guide for emoncms.org? The examples in Docs/USING EMONCMS are fine but describe only very limited setups.
