Question about Philips Hue Tap dial switch

You can control up to three rooms or zones with the buttons on the Tap Dial Switch, but it is not directly possible to control individual lamps without controlling the entire room. The buttons are designed to change scenes or light states in a room or zone. If you want to control individual lamps across multiple rooms, you need to set this up via the Philips Hue app by assigning specific lamps to a scene or room.
