With a Philips Hue switch, you can replace your old-fashioned switches, or make traditional light switches smart. The Philips Hue wireless dimmer is a smart light switch and remote in one. Stick the holder with the dimmer on the wall and take it out easily. Prefer to keep using your old switches? Place a Philips Hue wall switch module behind the switches. This way, your Philips Hue lights are always powered and accessible, even when you turn off the light switch. With some Philips Hue switches, you can also set routines and light scenes. That allows you to change the atmosphere with the push of a button.
