No luck, so far yet.
Got the online (almost) realtime info on huawei portal - in the cloud from my installer but prefer a offline, local storage.
The device seems to be prefering the wlan connection instead of talking over the rs485.
Tried the modbus over tcp but no succes either. I am not willing to give up the portal (yet).
They kindly installed an extra Landis & Gyr E350, that talks ODIS over IR. Got some (other) values to start with…
