This is a WIP. There are some issues when an area is selected.

Any reason to take switch vs light ?

I guess next step will be to turn it off or you separate the logic ?

@clempat, you can't select multiple domains with blueprints today so if your controlling method is a switch you'll have to use one or the other, they are exactly the same minus the domain :.

I also found it much more intuitive to separate the logic for turning on/off. That way you can compose multiple automations for turning on lights and have one smart one for turning off. Does kind of complicate blueprints a little bit but your automations are much easier to debug and work with. Now you only ask yourself. Why didn't it turn on or why didn't it turn off.
