I am looking to get a shunt KG140F to monitor my battery voltage, current, and SOC. It supports modbus over rs485. The problem is the manufacturer’s implementation of modbus. They have provided the documentation but i don’t know how to get HA to read register 50 which contains voltage, current, and SOC.
Someone has writen a code (not pyton) but i dont know how to convert to something HA can read.
Any help appreciated.
