what i am trying to do is
i want to use a select_input dropdown menu for my harmony
and i tried to make a group of 3 lights they are in the same spot so if i turn one up or down the other 2 have to do the same.
i tried this but it doesnot work. i put this in groups.yaml
tv_lights:
name: TV_spots
entities:
- light.tv_spot_1
- light.tv_spot_2
- light.tv_spot_3
I am not completly newby but this is the first time i try a input_select and a group
