Q-Cells X3 Modbus Communication is not working anymore

Describe the bug

Ich habe einen Q-Cells X3 Hybrid Inverter am Laufen. Ich greife auf dessen Daten über Modbus TCP (mittels RTU über einen RS485/Ethernet Converter) zu. Das hat immer wunderbar funktioniert. Der Converter und der Inverter funktionieren weiterhin - das habe ich mittels eines Python Skripts getestet (die Werte des Inverters lassen sich auslesen).

Ohne Änderung der Konfiguration o.Ä. funktioniert allerdings nun EVCC nicht mehr. In den EVCC-Logs sehe ich diesen Fehler: energy: read failed: modbus: response slave id '0' does not match request '1' Ich habe wirklich nichts an der Konfiguration geändert. Insofern meine Hypothese: Kann es sein, dass mit dem letzten Update ein Bug eingeschleust wurde?

Steps to reproduce

Check Config.
Start EVCC.
Check for functionality -> not working
Check logs -> Error message: energy: read failed: modbus: response slave id '0' does not match request '1'
Check connection and functionality of inverter/RS485-Converter via custom python script while EVCC is NOT running -> working
Check manual readout via custom python script while EVCC IS running -> not working (RS485 converter seems to get flooded by requests)
