When trying to request values from my inverter via pymodbus (ModbusTCP2MQTT) everything was fine. Since last week, I am experiencing errors in the log and some values are not displayed:

Getting these errors in log files:

This is very confusing,

there are no pymodbus v0.3.3.1 ?
How come you are using HASSOS without homeassistant ?
If you are using homeassistant, then the modbus integration started to use a new version of pymodbus in the current beta releases.
without a proper debug log, it is impossible to tell what might be wrong.

Maybe try to remember what happened to your system last week, if nothing happened then it looks like a device problem.

And just for reference new Homeassistant with newest hassos works nicely with pymodbus.

Hi Jan, sorry for the delay. In the meantime my Home Assistant installation had a HDD crash. I had to set it up again from scratch.

I am using now ModbusTCP to connect to my SunGrow PV Powerplant. Working as expected at thew moment. Thanks for your help and sorry for the confusion.

Cheers, Stefan
