The list just updates. I tested by saved the group with just one light, or even without any members. It gets saved without problems. Just the behavior doesn’t change.
And regarding the development tools I don’t know how to interact with this light group as it doesn’t have an entity id - or at least not one that it tells me. It does not appear under “States”.
Have the same problem with a “switch_as_x”. I’ve also removed all the reference to what I believe would be that “switch_ax_x” in the “core.entity_registry” and restarted and it’s still there.
Have the same issue with binary groups. All of a sudden just doesn’t work but the entity id is unavailable. Very annoying since this group is used by many automations and manually changing them all is going to be a chore
I had the same issue. If you haven’t resolved yours yet, try this:
Go to ‘Settings’ - ‘Entities’ - ‘Filters’ - ‘Status’ and select ‘Disabled’. Click on the light group you want and choose settings. There is a ‘Delete’ option, which I used to remove the broken group.
I edited the file “core.config_entries" (deleted the red exclamation mark helpers).
Saved the file and
restarted the whole system (Raspberry Pi).
That worked!
