The GE Cync Smart Light Dimmer and Motion Light Switch adds smart bulb functionality to traditional bulbs and keeps LED smart light bulbs smart. The smart WiFi switch works as a dimmable light switch with a wireless motion sensor while enhancing the traditional bulb functionality to include out-of-home control, scheduling and scene setting. With motion sensing and ambient light detection, set lights to turn on or off based on natural light and motion in the room. When Cync or C by GE Smart Bulbs are installed, the dimmable motion sensing light switch allows app or voice control even when power is turned off at the switch. Pair the dimmable light switch with Cync or C by GE Smart Bulbs in other fixtures like table lamps and control all your lights in the room from one wall switch. Our smart dimmer and motion switch wirelessly connects with other Cync or C by GE Smart Switches so you can control the same light fixture from multiple switches – connecting the switches wirelessly still applies, even if the switches are on different circuits. Install the WiFi motion sensor switch on your own with easy, DIY setup or with the help of a professional in homes built prior to the 1980s with a ground wire using 2.4 GHz WiFi. The dimmable light switch connects directly with Amazon Alexa and Google Home devices without a hub required. This LED dimmer switch works with most common residential wiring–no neutral wire required.
