Entity not longer showing in group

After my SD-card broke I had to reinstall. After using my backup I have a problem: one entity does not show up although it’s being recognized (e.g. in the panel)

But no luck in the group. “Nachtlicht” ist just missing…

My groups.yaml:

lichter:
  name: Lichter
  entities:
  - light.gateway_light_f0b429cc315f
  - light.romy_licht

Any ideas?

Could the entity_Id have changed? Check the States ( < > ) tab.

yay for backups!

No, the ID is still the same. :frowning:

yay for backups!

Yes, couldn’t be more true… :smiley:

EDIT: Solved. I commented the “custom_ui_state_card” in my customize.yaml out. Some installing for this custom state card might be missing. I’ll look later into that. Works for now.
