Hey!

I just finished updating to 2025.12.x and looking at the new Energy Dashboard.
I tried adding my Active Power meter as a Power Sensor under the Grid Power section but when I do I see a "Entity without state" warning and it doesn't work.
Apparently everything's fine with the entity so...what am I missing here?

Can you look up that sensor in Dev tools => states. Does it have a state, a device class and a state class?

thinks that's exactly what I've posted above?

#

#

doesn't have a state class so maybe that's it?

#

entity is based on ESPHome so maybe I'll need to edit it and add
state_class: measurement ?

OK I can confirm it was the lack of a state_class on the ESP home config. thanks
