A:Answer If you have your Phillips Hub set up, the app on your phone and a powered bulb socket in the staircase your good to go. 1. Put the bulb in the light socket and turn the power on. 2. Pull the plastic strip from the battery area of the switch. 3. press the button on your Hue Hub to detect the new items. 4. Go into the App on your Phone, add a new room, and select the new items to go in that room. The switch will control all of the Hue bulbs in the same room group that it is in. Good luck.
