Update solarman.py

Repair python 3.12 issue. Now it works but without logging. After something about 21 march 2024, changes to HA core made this component unusable. That little fix will work, but without logging from pySolarmanv5

Without logging means I don't get the current power?

No it means that You will not have logging from PySolarmanv5, debug and normal messages. Sensors will start to work. If You are not programmer developer You don't need that.

Thanks for your work and your reply. Sadly this fix is not working for me either. Does this integration work at all if you use the intermediate relay from deye in addition to the inverter?

Solved it by downgrading to 1.4.3.
My inverter is deye sun-m80g3-eu-q0.

So I tried this fix but I still have an error about a read only filesystem.
I added some more handling to see the exception.

I fixed this issue by forking https://github.com/jmccrohan/pysolarmanv5/blob/main/pysolarmanv5/pysolarmanv5.py from the package to the local plugin directory and replacing the "multiprocessing Queue" with the standard python Queue.

the issue with /dev/shm? I traced it back to a change in docker-ce, I reverted docker-ce to the version 24 and It works again. I dont think this is meant to be read-only. But its not resolved in the homeassistant image yet.
