I have a python script for getting several values from the cerbo gx using the modbus tcp protocol.
All the registers i used was from the modbus register list provided by victron. For example, i accessed the values like
Load = client.read_input_registers(860, 1)
Solar Voltage = client.read_input_registers(776,3,unit=226)
Unfortunately im not able to read any batterystate. The register used in the modbus list is 844, but i dont get any readings, such 0,1, or 2 . This is what i use.
Any help is appreciated. Thanks !!
