I made an integration of the DaheimLaden Wallbox for myself using the HA Modbus integration. I control the wallbox via EVCC from a different IP address, (it could be done by HA or by EVCC, but I don’t need to control it via HA).
Note: The modbus server just allows one connection, because of this I installed the HACS modbusproxy add-on to query the values from the Modbus). If you don’t need that, you don’t need the modbus proxy.
It is still working but I cannot say for sure until now if it’s working wihtout any issues. It needs some more testing:
Added this to the configuration.yaml:

It looks like this now:
and my power flow card, using powerflow card plus looks like this:
