I'm trying to group IKEA LED2201G8 light entity and one of the switch entities of the Tuya TS0012.
I started by creating a helper to change device type of a switch to light.
Then I'm trying to create a light group containing two entities, one is the original light, and the other is the fake light from the switch.
When I click preview i get an error "Failed to perform the action light/turn_on. not a valid value for dictionary value @ data['entity_id']"
How should the light entity and switch entity be combined to get one light entity I can control from other automations and android widgets as one thing?
