I’ve seen that on startup sometimes until one light reports something. I’ve never opened an issue, but I’m guessing it happens when the light group is created before all of the lights are available.
okay. Check if the group comes up when you reloading them by clicking on Groups, Groups Entities and Notify Services in Configuration → Server Controls.
The name field should be a human readable name like “Hall”. HA will then create an entity_id of light.hall. You have effectively created an entity_id of light.light.hall which HA probably wouldn’t accept because of the second period. If I had to guess I would say that the actual entity_id created was light.light_hall. Since no entities were created with the name light.hall etc, there are no valid entities for the group you create. That is why it’s showing as unavailable.
The correct definition would be:
- platform: wiz_light
name: Hall
host: 192.168.1.233
That would give you a light with entity_id of light.hall that would then match entities being referenced in the group.
