If you have created different scenes with Casambi app you can control them from a single power switch.
Select which scene you want to control and turning on one luminaire will also turn on all other luminaires in that scene. Turning off the luminaire will turn off also all the luminaires that are currently controlled by that scene.
If the luminaire has been controlled by some other way, for example from Casambi app, then it is no longer part of the scene and it will not turn off.
Select the ‘Control Scenes’ option from Smart Switching and tap on the desired scene to select it. Confirm changes with ‘Done’
