I'm relatively new to emoncms.  I've had a Brultech GEM for a couple of years, and was using Smart Energy Groups website for monitoring.  I decided to try emoncms a couple of weeks ago.

I've had a raspberry pi lying around for a while, so I decided to install btmon.by on it, and forward the GEM data to emoncms.org.  I created an account on emoncms.org, and successfully got btmon working to send the data.  Then I decided to install emoncms locally on the raspberry pi.

I bought a 1TB USB driver to attach to the raspberry pi, installed the Debian Wheezy and emoncms.  After a bit of trial and error I got it up and running, and got btmon.py to forward the GEM data to the local emoncms.

The GEM has CT 32 channels.  Each channel provides a real time watts reading, and an accumulated wh reading.  It also has some temperature and pulse readings, which I don't use.  The inputs to emoncms are working and are updated fine, and when I create a feed using "Log to Feed" for the read time watts reading and it appears to log correctly.  However, when I create an feed with "Wh Accumulator" for the CT wh data, the feed shows "inactive" with a value of NULL.

I think this was working fine on the emoncms.org site, but doesn't work on emoncms on the raspberry pi.

I decided to try upgrading the pi to Debian Jessie, and reinstall emoncms and btmon.  I get the same results.  "Wh Accumulator" doesn't work.  For now, I've just created feeds for channel 1, the Main power.

I followed the following URL to install emoncms on Jessie: https://github.com/emoncms/emoncms/blob/9.0/docs/RaspberryPi/install_Raspbian_Jessie.md

I've attached screen shots showin the Main power, Main wh, and my feeds.
