Cync - Smart Dimmer Switch, No Neutral Wire Required, Bluetooth and 2.4GHz Wifi - White

The GE Cync Smart Light Dimmer 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 while enhancing the traditional bulb functionality to include out-of-home control, scheduling and scene setting. When Cync or C by GE Smart Bulbs are installed, the dimmable 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 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 smart switches 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 smart light switch connects directly with Amazon Alexa and Google Home devices without a hub required. The LED dimmer switch works with most common residential wiring–no neutral wire required.

Compared to the Lutron Caséta Wireless Dimmer, the Cync switch is easier to install in homes without neutral wires but lacks Caséta's robust ecosystem and near-zero flicker performance. The Leviton Decora Smart Dimmer requires a neutral wire but offers more consistent dimming and supports Apple HomeKit, which Cync does not. The TP-Link Kasa Smart Dimmer also needs a neutral wire but has a more polished app and faster response times. So, if you lack a neutral wire, Cync is a rare option, but if you have neutral wiring, competitors provide better reliability and features.
