Hi,
I recently picked up a Emporia Vue 2 to monitor my energy. I confirmed that it all worked with the Emporia app and then flashed the ESPHome firmware on it and so far it’s been a nightmare. I double and tripled checked the firmware and clamping directions, everything looks correct. At first I was consuming more energy than the grid was supplying (I have no solar panels or any other source of energy).
Now I am seeing sort of the same issue but with a different graphic. I have 5.5 circuits that aren’t part of the main energy flow, they’re just floating in the breeze (see below).
If I look closer at the individual devices, it is reflecting just that, negative energy usage.
My setup is very simple, I have a main panel and subpanel in the garage. I have 2 clamps for the subpanel, one for each leg, and no x2 multiplier. Aside from that breaker, I only monitor 1 other 240V double-phase breaker with a single clamp and a 2x multiplier, and the rest are single phase.
The code that is running in the firmware is below, it is pretty much a copy-paste directly from the ESPHome Git repository. I am trying not to change much until I can get this basic setup working.
