Additional context

The inverter was in "Waiting" mode, which means some registers are unavailable. This worked fine with version 2024.11.2.

[Haydn23]

Hi, I have same issue, all showing Unknown

[wills106]

Looks like it's trying to setup two instances. If you delete the Inverter from the Integration and add it back in again does it load correctly?

[Haydn23]

have deleted mine and reinstalled, still same issue here. all items showing unknown. Only happened since last update.

Same problem for me. I did a rollback to version 2024.11.2

[wills106]

Can you all try 2024.12.2

[Kars-de-Jong]

@wills106 Works for me now, thanks!

[wills106]

Closing down as resolved.
