The Philips Hue wall switch module is installed behind existing light switches, allowing you to seamlessly integrate your Philips Hue smart lights with your traditional switches. It ensures your smart lights remain powered and reachable at all times. You can use the switch to control individual lights, rooms, or zones, and even cycle through different lighting scenes with multiple toggles of the switch. A Philips Hue Bridge is required for operation. This module is IP20 rated and comes with a 2-year warranty.
