Why is this happening and how can i hide the double entities from the develope panel?
light.bedroom is the actual light-bulb, light.bedroom_2 is the Hue group (the room you declared in the Hue application). There’s a is_hue_group attribute set to true on the group. From the documentation, you can set allow_hue_groups to false, you won’t see them anymore. But you won’t be able to interact with them either. It might be useful to keep them if you end up having multiple lights per room - this way you can light them all together.
