@LRvdLinden just found your app while looking for an easy way to solve this. I was wondering if it might be possible to extend/duplicate some of the cards affecting multiple lights to read something like this:
Dim [[light_state]] lights for [[zone]] to [[%]]
Set [[light_state]] lights to color [[color]] for [[zone]]
- etc
With light state being either all
(default), turned on
or turned off
.
Because I think only wanting to influence currently turned on lights in a room for example is a pretty common use case.
