Smart Energy Usage monitor with a Sonoff S31

I wanted a way to monitor power consumption through my 2nd battery and have data/unit operate through a Raspberry Pi running Home Assistant. The Sonoff S31 is exactly what I needed!

Although this doesn’t monitor 12v specifically, it will work for my needs to monitor power usage through my inverter.

Next up is to upload the Tasmota firmware and integrate into my Raspberry Pi running Home Assistant!
