GE CYNC Smart Dimmer Light Switch & Motion Sensor, No Neutral Wire Required, Bluetooth and WiFi 3-Wire Switch, Works with Amazon Alexa and Google Home, White (1 Pack)

No Issues. Works perfectly
I use this product with the Google Home eco system. Was looking for a switch that did not need a negative wire and no additional piece to plug into a near by outlet. This met the those requirements. Almost didn’t purchase after reading reviews stating product randomly activates/deactivates and intermittentoperation. I have 2 of them now and planning to purchase more. Never had issue with intermittent operation. Works every time. Light did turn off “randomly”… noted the switch was located where there is low activity. Looked in the cync app and found a set of options for motion control. Turned it off and never had that issue again.One switch controls six lights on one circuit a d another 3 lights on one circuit. Works great. Put the adapter that comes with the switch on only one light. No issues.Love the way they look, ease of installation, and google home automation.

3 wire (no neutral) motion dimmer has been a major headache & disappointment
The Cync/C by GE motion dimmer smart WiFi switch that is the 3 wire no neutral wire required version has been a major headache & quite disappointing. I purchased 3 on/off toggles (3 wire) and no issues with those (besides the fact I couldn’t use my existing WiFi or zwave smart light bulbs it led dumb light bulbs)… but the 2 motion dimmers (3 wire) have been quite frustrating. First off there’s an adapter that must go on the light fixture & you can screw 1 light bulb into it (only need 1 adapter per light fixture not per each light bulb). Second regular led & smart light bulbs didn’t work and would blink on the fritz. Third con is the set up was tedious & kinda a PITA compared to all other smart home tech I’ve had experience with (which is a lot as I’m a smart home nerd). Fourth is that they kinda do the non compatible light bulb thing to force you to buy their Cync/c by ge smart light bulbs. Ok so I did so and I no longer experience any blinking but I’m still using an adapter with their c by ge smart light bulb on the fixture. Fifth con is that not all light fixtures will fit with the adapter. For instance I have some generic “boob” ceiling lights and the adapter piece made the light bulb stick out further that the glass bowl covering placement so I couldn’t use it with certain light fixtures. Sixth issue is that the light was constantly turning off and on when in the room for a couple seconds. Then at times the switch wasn’t picking up motion quick enough. I have a strong feeling there is no occupancy sensor in it & only a motion or vacancy. I liked that the app featured a setting where it will adjust due to the amount of natural light in the room BUT they didn’t have a setting of when to turn off or how long to keep on, etc. when triggered. Something so simple should be added. They only offer this for a manual physical press of the circle button. I was so excited about this switch for a home like mine that doesn’t always have a neutral wire in my light switch boxes. It’s definitely fallen short for me. I think I might remove and go back to regular occupancy Lutron light switches. At least I wouldn’t be stuck in the dark or about to have a seizure from the constant on & off. Maybe firmware or software updates will resolve some of the technical issues someday I hope.

That switch doesn’t connect properly with Alexa! Well, it does, but you can’t access it with Alexa! Totally defeats the purpose! Apart from that it loses connection with its own app frequently!And the bad thing is… It works on its own like crazy! The whole night it keeps turning on most of the night! I don’t know if it catches demons or spirits moving around the toilet! But it’s really annoying!I am definitely getting a standard non-smart dimmer for the bathroom, and forget about the whole hassle!Do NOT recommend it!

I have Leviton switches throughout my house, however my basement is without a neutral wire. I just installed a pair of these and super impressed with the grouping functions. It also has a lower profile than Leviton so I found them an easier fit. Work great. Set up easy using the new Cync app and works great with Alexa. Just ordered another two to finish off the basement. They’re a bit pricey, but highly recommend if you do not have a neutral wire.

UPDATE: After a month of usage, it made short circuit internally with no warning or security mechanism to protect it. Almost got everything on fire. I NO longer recommend it.—–I thought the cause for no-neutral smart homes was lost, with not many options and super expensive ones for whatever is available. This was a great surprise, great ingeniosity was used to design this product. For sure, it’s not perfect and has its limitations, but installed in a 2 wire box? It does more and works better than I expected!
