GE CYNC Smart Dimmer Light Switch, Neutral Wire Required, Bluetooth and 2.4 GHz Wi-Fi 4-Wire Switch, Works with Alexa and Google (1 Pack)

The Smart Switch-Dimmer adds smart bulb functionality to traditional bulbs and keeps smart bulbs smart. The smart Wi-Fi switch works as a dimmer switch while enhancing the traditional bulb functionality to include out-of-home control, scheduling, and scene-setting. When Cync Smart Bulbs are installed, the smart switch allows app or voice control even when power is turned off at the switch. Pair the Smart Switch with Cync Smart bulbs in other fixtures like table lamps and control all your lights in the room from one wall switch. Cync Smart Switch wirelessly connects with other Cync Smart Switches so you can control the same light fixture from multiple switches. Simply DIY set up. The Smart Switch connects directly with Google Home and Amazon Alexa devices without a hub required. Neutral wire--usually a white or gray wire--is required.
