Monitoring an EPSolar/EPEver Tracer Series A Solar Charge Controller

I’ve just finished hooking up my solar charge controller to OpenHAB (more for getting the graphs, but also many potential uses for automation). Mine is a 1210A, but should work with any of the RS485 based ones.

It uses a NodeMCU board, and a RS485 adapter to talk to MQTT, and then get pulled into OpenHAB.

Done a write up incase anyone is interested:

Code is all in Github:
