SMA integration stops working

Hello,

I have updated HA to the latest version and all my entities related to an SMA inverter have stopped being updated.
After removing the device and creating it again the entities are not created anymore.
I can log to the web interface ot the inverter as usual.

Please ask me for any more info as needed.
Cheers
Julien

Below is the related log (I suppose)

I had the same issue after updating on 2025.11.3
I have rolled back to .10.4.

After checking change log of .12 I didn’t find any SMA related changes (e.g. bugfixes). So, I am not convinced at this time to update.

I just tried to update to 2025.12
Again, no success. SMA integration doesn’t show entities any longer.

Rollback in progress.
