[Bug]: Integration not working with any version after 2024.09.5 / all entities unknown

[ggliniak]

Describe the bug

Hi,
after upgrading to 2024.10.1 this integration stopped working in my installation. Absolutely no changes to my modbus or inverter configuration.
I waited some weeks and did a try to each update, also to the newest 2024.12.2 yesterday, same behavior.
(did all the known steps like removing integration completely, restarting HA, doing it when inverter is well PV powered, and so on)

Modbus communiation is working rock-solid (Schneider Electric PAS600 as modbus gateway).
Each time after downgrading to 2024.09.5 integration is starting to work immediately again (although in night time when inverter is asleep).

Noticed that newer versions (>2024.09.5) can read my serial via modbus but are NOT reading the full firmware informations, see attached screenshots.

Is this a known behavior and I was not able to find the solution it here in the documentation? If yes, please give me a hint! ;-)
Or is this a new situation?

Best regards, Georg

I have exactly the same situation here. Waiting for an update ...
Tried to delete the integration, shut down the inverter, disconnected modbus cable. No way to get it working again.

Best,
Dirk

The same applies to me. The hardware and serial number are still recognized, but the FW versions and all settings or values ​​are missing.
