I am hoping I am just missing something. I have 2 groups of lights in my kitchen. I control one group of lights in a room called Island, I have another group in a room called Round. What I would like to do is put both groups in a room called Kitchen so I can tell the assistant to turn off kitchen and all the lights will go out, but I can still control each group independently. Is this possible in GHA? Or is there a place I can group devices without a room? I may be setting this up all wrong. I have it like this on my Alexa but am hoping to move off of that.
