Powercalc doesn’t create new energy sensor because of duplicate, but I can’t find it

Hi Community,
I get this protocol error everytime I try to create a specific energy sensor in Powercalc:
„This entity has already configured a power sensor. When you want to configure it twice make sure to give it a unique_id.“
But I can‘t find the duplicate sensor in my system - Have anyone had the same problem or an idea how to find the duplicate sensor?

Regards,
Denny

Where have you looked? I assume you’ve already gone to Services | Devices & Services | Entities and done a search for “Powercalc”?

Yes, sure.
I managed to change the source sensor name and tried it again with Powercalc. That worked for me. But no clue where the sensors are stored on my filesystem :man_shrugging:t2:
