Whole home energy monitor w/ Grafana charts PROJECT
With the interest in electrical power monitoring from the latest Home Assistant update, I thought it would be useful to point out that Grafana is a pretty good tool for visualizing power usage. I'm working on putting together a more complete tutorial of how I set up the system, but here's some screen shots of my Grafana dashboards. I have a pair of CircuitSetup 6-channel modules, giving me 12 channels. Two used for the main incoming breaker and ten channels for branch circuits. I'm pushing watt data into InfluxDB via MQTT and Telegraf. And then using Grafana to make charts.

I've got two of the circuit setup "boards" running ESPs on WiFi without any issue. Once is a two clamp module for the mains and the other is running 5 extension boards monitoring all 30 breakers. It's pushing all metrics (amp, watt, freq, volt) via HA api every second and the WiFi impact is negligible.
