A simple example of how to read the Modbus registers on a Midnite charge controller 🙂 I am really impressed with the Modbus integration 🙂 thanks everyone
The hardware was what I had on hand - the linked hardware in the repo is what I would recommend anyone else use and what I am ordering more of for the future ones I will build. But basically any ESP32 + RS232 + DC-DC converter will work.
