I am trying to figure out how much energy is storged to and retrieved from the battery on daily basis. Could somebody help me with figuring out how to read this values from the CerboGX? It also would be fine if I get the active power reading of the battery so that I can do a rieman calculation to figure out the energy.
I tried to read modbus register 301 and 302 on slave 225 (my Plytontech) but it always returns zero. On the CerboGX itself (slave 100) the registers do not seem to exist at all. So how to get the information?
Thanks in advance
