I’m not using any smartapps for my energy monitor use.
I’m using a custom device type discussed here:
Specifically, I’m using a cut down version of the app that Slowfoxtrot put together and posted here:
I now believe the meter to be ~95% accurate, by comparing my usage with the power company’s meter. It meets my needs just fine. I’m not sure if the Gen2 would be any more accurate.
I’m going to double check my install of the clamps to make sure everything is solid. Maybe I can get the accuracy up a little.
