Product Description

The Smart Motion Sensing and Dimmer switch adds smart bulb functionality to traditional bulbs and keeps smart bulbs smart. The smart Wi-Fi switch works as dimmer switch while enhancing the traditional bulb functionality to include motion sensing, out-of-home control, scheduling and scene setting. Pair with a voice assistant like the Google Assistant or Amazon Alexa and experience voice control without an additional hub required. 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. With motion sensing and ambient light detection, set lights to turn on or off based on natural light and motion in the room. Smart scheduling disables motion sensing during times you do not want to be disturbed. Now you can control your lights with touch, app, motion or voice and get more from your lighting.

    Works in old home with metal box
    I wanted to write this review because I was reluctant to buy this but it actually worked. I saw many reviews about it not working in metal boxes and not being able to connect to WiFi. So I was scared because my switches are on the third floor in a metal box. And I have a very old house with old wiring. BUT IT WORKED !!. the instructions in the box are terrible and incomplete. If you are looking to install as a 3 way switch you must go online to c by ge website for the instructions. It is a completely different set of instructions that are not included in the packaging.I’m not an electrician and not sure about code, but if you have a metal electrical box and don’t have a green or copper wire double check for a ground screw in the junction box. This could still work. Again I’m not an electrician but this came up in my research so use your own judgement. I hope this helps someone thinking of buying this product.
    Thank you for your feedback

    1.0 out of 5 stars Beware the bulb adapter!
    Reviewed in the United States on April 22, 2022
    This review is for the single pole dimmer+motion sensor (no neutral wire). It's pretty...but not so smart! Installation was straight forward but it just doesn't work! The motion sensor is not accurate and WiFi connection drops/disconnects often. Be aware that the actual switch uses Bluetooth Mesh (as noted in the app). The WiFi connection appears to be only for voice integration and app control. This is is the MOST IMPORTANT part of this review...if you read the documentation, there's an included adapter that screws onto one of the bulbs, it's needed in most installations. The adapter is about half the length of a normal LED bulb and will effectively DOUBLE the length of ONE (yes, just one) bulb in your fixture (I've included photos of the adapter). It looks ridiculous and didn't even fit into my fixed ceiling fixture...a typical globe style light with glass cover. I installed and set it up anyway only to find that it worked for about 20 minutes before the connected bulbs started to flash then the switch indicator turned red and the lights remained uncontrollable in the on position. Even a factory reset of the switch didn't correct that behavior. I wasted about an hour on trying to resolve It, then just removed the switch and boxed it back up for return to Amazon. Save yourself some trouble and skip this item. Just trust the reviews and look for something better. Wish I'd done that also.
