You can assign different light mode, custom color and brightness level to the two zones. If you turn the device OFF (both zones) by the app, voice, or control accessory, and turn it back ON, the two zones will turn on to their last status (i.e. the light mode, color and brightness before it was turned off).
Note: if the light doesn’t turn back to its last status, check if you have a Rhythm enabled for the given Room.
