Product Description

The Cync On/Off Smart Switch adds smart bulb functionality to traditional bulbs and keeps smart bulbs smart. The smart Wi-Fi switch adds out-of-home control, scheduling and scene setting to traditional bulbs. When Cync or C by GE 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 or C by GE Smart Bulbs in other fixtures like table lamps and control your all your lights in the room from one wall switch. C by GE On/Off Smart 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. Simple DIY set up. The Smart Switch connects directly with Google Home and Amazon Alexa devices without a hub required. Works with most common residential wiring– no neutral wire required.

    Works well but requires retrofitting if installed in bank of switches

    Works well but requires retrofitting if installed in bank of switches
    I installed this in a bank of 3 switches. As others have noted, the body of the new switch is thicker than a conventional switch, and required a little retrofitting. I removed some of the drywall and then used a Dremel tool to sand the switch box in the wall so the new switch would fit deeper and allow the cover plate to fit flush. I also had to sand some ribs and protrusions on the back of the switch plate in the area of the new switch so it would fit. A little extra work but was able to get it to fit. Setup was fairly easy using the Cync app and works well with Alexa. I installed this to switch on/off the separately switched fan of my ceiling fan so I can't comment on how it may work to dim or control lights. My only complaint is that the switch only comes in white so doesn’t match my existing almond switches.
