In my example the state is 0. State for sensor.tonnen could be 0 / 1 / 2 (will changed automatically based on date calculation)

Consolse shows only: CARD-TEMPLATER Version 0.0.8 Unfortunately nothing in the log Screenshot if default picture entity card is added to the view, everything works 

Yes the config looks exactly same. I also edited my first post, there was a issue with the "insert code" function and the first line "type: 'custom:card-templater'" was not displayed

I tested a little bit: Custom card on View 1 --> Custom card don't work Add a defafult picture-entity card to view 1 --> Custom card works Custom Card on...

In my environment everything is working totally fine 👍
