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.

    Customers are mixed about the performance of the electronic switch. Some mention that they work great once they are set up, while others say that it was difficult to get working properly. The programmed schedule and the lights randomly stop working with Google and Alexa. They are unresponsive. The directions state that it doesn't work with led bulbs, but does have an adapter to use for. The BIGGEST issue was trying to get the second switch working, as the app seems to respond slowly.

    Customers have connectivity issues with the electronic switch. They mention that the switch loses WiFi connectivity, and the indicator on the paddle that's supposed to show connectivity is not working.

    "...them on and off from the app without issue, but they're all indicating they have no WiFi...." Read more

    105 customers mention11 positive94 negative

    Customers are dissatisfied with the quality of the electronic switch. They mention that the app is terrible, mediocre, and confusing. The setup is horrible, and the application has many bugs. The error messaging and troubleshooting were non-existent, and it's unbelievable how negligent and idiotic these companies are.

    "...I've returned 3. Two were "Used Very Good" and were defective. This was no fault of Amazons since these were from third-party sellers on the site...." Read more

    "...that will not respond at all, cannot be factory reset, can't be operated through the app, and won't start functioning when I power cycle the..." Read more

    "...on the fourth set it was making some percolating sounds and kind of flickering...." Read more

    "...I STILL had issues with lights flickering, and the switch losing power. I then installed the adapter - so that's 30W of bulbs AND the adapter...." Read more

    "...First try, lights just flickered. Installed the adapter and tried again. Same result...." Read more

    61 customers mention9 positive52 negative

    Customers are dissatisfied with the light. They mention that it will not allow the ceiling light to turn off completely, it constantly dims and brightens the lights, and the toggle has a light in it. They also mention that the noise and the red light are a concern, as this switch has only been in use.

    "...Additionally, with the fourth set, the bulbs appeared to be dim and kind of burned out. It's now nearly impossible to get fluorescent tube bulbs...." Read more

    "...and the light would still strobe when on, and wouldn't turn off completely with the switch off...." Read more

    "...Did that for probably 2 minutes and the light never turned red. Tried it again and it still didn't work...." Read more

    "...The dimmer switch lost the ability to dim, I had reopen the C By GE app and re-select the bulb type, then it was working again...." Read more

    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.
    Thank you for your feedback
