i doubt it. We do not even have any idea what version of openHAB you are referencing.

@Bruce_Osborne Sorry for that!

I’m using OH3 stable with influxdb persistence.
Persistance in general is working as expected. I dont know how i can see which item is affected on this nullpointer.

If you upgraded I think I read some people needed to start with a fresh database. I have not used persistence much.
