In the Hue app I combined two lights into a zone, I think HA calls that a HUE group. I have since renamed the group in the Hue app to a more convenient name.
in HA I still see the old name, however I can’t change it, I get this message:
This entity (“light.bank_2x”) does not have a unique ID, therefore its settings cannot be managed from the UI
So I can’t change the name or delete it (hoping it will reappear after a reboot with the correct name
