Any other user in possession of one of these energy meters? https://www.google.se/search?q=energy+count+3000&tbm=isch ?
I am currently feeding data from these into HA using än external process (using the ec3k python module: https://github.com/avian2/ec3k) but I’m thinking about integrating it as a sensor, if there is someone else that also would find it useful.
