The new smartthings app has an option to group a set of lights, which I can control on the app, all lights at once, or dim all light at once at the same level.
I cannot associate this to a switch/button. All I can do is to make an automation to switch on or off several lights while pressing a switch/button/sensor etc, but they do not turn off at same time because the routine switch them in sequence.
Any way to turn on/off/dim all at once?
Thank you all
