The 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. The 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 without a travel wire, 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. Neutral wire–usually a white or gray wire–is required.

So far, so good!
I was installing this to control our porch lights. I had wanted smart switches to replace a number of existing switches in our older home. However, all of the ones I had previously reviewed required the neutral wire, which we do not have. So, I was very happy to find the GE Cync which does not need it.Installation was straightforward. Only took about 15 minutes after I figured out how the existing switch was originally wired. The switch is controlling 3 LED lights on the porch. I had no issues installing, the app worked immediately, the device was added to Google Home, and I was able to control the lights by voice, through the app, through Google Home, and of course manually flipping the switch. There are other traditional non-GE Cync switches on the circuit, and everything seems to play nicely with each other.I’m very happy at this point.Update 1/9/23:I’ve installed the second switch controlling an outside light above our garage. Initially it had a 60 watt LED and using only 5 watts, was below the 15 watt required minimum and so it was flickering. I swapped for a 300 watt equivalent, 33 watt actual, and it worked fine.I set up a scene/routine to turn the porch and outside garage lights on 30 minutes after sunset, and off a few hours later. Works with no issues whatsoever.Having seen these work, becoming more familiar and comfortable with them, understanding the benefits, I ordered another 12 GE Cync switches of various flavors and will probably add more over time. Our 1960s home has many of the original switches, and it’s wonderful that we can bring it in to the modern age without much effort, even with the old wiring.Update 1/17/23I now have 12 switches installed and working well, and more received and waiting to be installed. Since I’m doing so many of these, I thought I’d pass along lessons learned that may help others.3-way works just fine. As another comment/reply mentioned, travelers aren’t needed. By default, all lights within the same grouping will be switched on/off when any of the switches in the group is toggled. Just wire each independently and handle the 3-way functionality within the app and/or Google Home.In one bedroom, we have track lighting, where there is a power adapter/injector at one end that plugs into a wall outlet controlled by a switch. The GE Cync switch works in this configuration. Don’t plug anything else in to the outlet controlled by the switch. We originally had six 60 watt equivalent LEDs in the track lighting (8.5 watt each) and the switch did not like the configuration at all through the wall outlet. I swapped out one of the LEDs for a traditional 60 watt incandescent, and it now works fine. The incandescent and five LEDs are all 60 watt soft white and you cannot tell any difference between them at all.If you have multiple switches in one room, by default, without changing any settings, using any of them manually by hand will control all of them. If you want them to be independent, then put each in its own group within the app. Within the app, all the switches in a single room can be controlled as a group (flipping the on/off toggle) or individually (click into the room and then flip the individual light). This is the same within Google Home.If you run into trouble with flickering, try using more powerful bulbs. I believe folks are seeing this so frequently because they are using LEDs and there’s really no guarantee what they are drawing, no matter what the info/spec says on the product page – most are cheap Chinese. If you’re using the switch on a single LED bulb, be aware that it’s going to need to be 150 watt equivalent if not more to get you above the 15 watts minimum. If more powerful LEDs don’t do it for you, then fall back to a lower power incandescent. If you have one switch controlling a bunch of LEDs and have issues, then change just one of the LEDs for an incandescent and it will resolve. I did this with the track lighting previously discussed as well as another location where there were only LEDs in a string.In our kitchen, we have two switches (dual gang) which are about 4 or 5 feet from the microwave. When the microwave is used, both switches lose network connectivity.If you purchased used/like new switches, the person who returned it likely tried setting up already. Out of the box, it will likely not be in setup mode when you put power on it. Hold the button or switch in the on position for at least 10 seconds and then let go, the indicator light should then flash blue for setup mode.I have found QA to be iffy. I’ve successfully installed 12 so far. 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. The third that was returned was new out of the box and electrically would not power the lights. So, keep this in mind, as there are lots of used ones and this should alert you to the fact that folks are returning many of these for one reason or another. Also, factor this in when you purchase – depending on the price differential, for a few extra dollars it may save hassles and headaches if you just buy new.DW ordered some Kasa smart plugs. I told her to give them to friends or family, I’ll buy the GEs so we can have it integrated with the GE app.We continue to be very happy with all of it thus far.Update 1/25/23We now have over 20 devices installed and doing well. For those asking if the switches work with fluorescent bulbs – yes, for me it is. In my garage, we have four sets of four four foot fluorescent tube bulbs – ceiling mounted shop lamps. I was unsure if the GE Cync switch would work, but I decided to try. One thing to be aware of – depending on the ballast, it may or may not work well. On three of our four sets, the switch worked fine. However on the fourth set it was making some percolating sounds and kind of flickering. I realized that a few years ago on the three working sets I had replaced the 40 year old magnetic ballasts with newer GE electronic ballasts. The fourth set still had the old magnetic ballasts. I had the replacements, just never got around to replacing. So, I took 30 minutes, replaced the old heavyweight magnetic ballasts and then all four sets work fine together on the one paddle switch. 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. My local hardware store had LED drop in replacements, so I gave them a try, and they worked great in the shop lamps with the new ballasts as well as with the switch. No problems.

Took a chance, what a headache!
I bought one of these switches because I liked the designed. Installation wasn’t too difficult, set up in the app was not the easiest but not overly difficult. The first one I bought was a dimmer switch with motion sensors, but I also bought multiple on-offs later.The dimmer switch with motion sensor was an absolute nightmare. GE says you should use at least a 15w bulb, or use the adaptor: “3-Wire Switches and Dimmers have a 15W minimum load requirement. Depending on the bulb type or the wattage of your lights, you may experience functionality issues that would require the use of the Cync Bulb Adapter (included in box)…”No problem, I bought 2 15W LED bulbs and hooked them up to the dimmer switch – for those keeping track that’s DOUBLE the wattage listed as required. 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. STILL had problems with the lights flickering and the switch powering off.I disabled the motion tracker entirely from the app, making the switch just a dimmer switch. All the problems went away, didn’t even need the adapter anymore. So while the switch appears to have around a 15W minimum, the motion tracker MORE than triples that requirement.So, after fixing my issues with that switch, I bought a bunch of dimmer and non-dimmer switches. I’ve had them installed in the house for a couple months now. They work pretty good, occasional issues with a switch not turning on when pressed, but a second press solves it. Might seem like I’m not hitting the button the first time, but the button makes an audible click when pressed, so it’s definitely getting pressed.Everything else is good – until today. Randomly during the day, every light switch indicates it can’t get WiFi. It can get WiFi, it’s on WiFi, I can actively turn them on and off from the app without issue, but they’re all indicating they have no WiFi. Worse still, they’re drawing extra current for some reason, making some lights that never had issues before flicker when they’re off. WiFi was working fine – connected via my phone to WiFi and it was fine, ran Netflix via my WiFi on TV and it worked fine. But all the light switches still indicated an issue.I tried factory resetting one of the switches so I could reconfigure it but that was a mistake. Once it had gone into setup, the app refused to find it. It could still find all my other lights, but even while the reset light was blinking blue (indicating it was ready to be setup), the app would not find it.Ultimately, I had to turn the breaker off to all my light switches to get them to reset, and I was able to reconfigure the one I had reset. Only trouble now, the one I reset now randomly turns off when the light is on. I can solve it by changing the bulb type (to the wrong type), but it causes the light to make an extremely loud buzzing noise, so I assume it’s doing something it shouldn’t be.All in all, it’s turned into a total nightmare. I can’t possibly recommend these switches. For the cost, they shouldn’t have anywhere near the problems they have. They’re $50+ a switch – at that price, they should be FLAWLESS.EDIT:My problems only got worse. I now have multiple switches 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 breaker.This is effecting switches on different breaker boxes and in different rooms. 1 of the switches is a 3-way with another GE switch and the other switch works fine, so this isn’t a light wattage issue. One of the non-functioning switches is in an electrical box with another GE switch that still works fine (including through the app) so it’s not a wifi issue. The switches have just stopped working – they’re completely dead.These switches are defective. They’re not worth $5 – yet alone $50.

No issue with the hardware. Fairly easy to set up provided you check to see if your existing wall jack has a neutral wire.The app required to make this work though is a different story. Poorly programmed. The text/font doesn’t scale with the device settings. Once the device is added into the app, it randomly disappears saying “no device found”. Links to Google OK but unable to control the device from Google Home once linked.Ended up returning.

So I was nervous after checking reviews on this product on the US Amazon site, but it works wonders for me. I’m using them for pot lights in my basement (that wasn’t wired with a neutral for some reason). Used 3 switches for 35 pot lights and works great. Easy install and setup. Of course it’s a lot more pricey than the other smart lights, but if you don’t have a neutral wire, you have to go with these. Integrated perfectly with my Google Home.EDIT: So after a few weeks I started to notice that the smart features cut in and out. Because this solves a problem of not requiring a Neutral wire, I would cut the product some slack. However, for the price, I expect these to work ALL the time. Unfortunately they do not (at least not with smart use).EDIT #2: Well, I figured out why it kept getting disconnected. The device doesn’t work well with band steering. So if you have a mesh system that uses both 2.4 and 5 ghz bands simultaneously and switches between them, it won’t work well. You have to have a dedicated 2.4ghz band for it to work well. But then it works great. Also, if you are using the switches for lights that are low wattage (below 18w) you NEED to use the bulb adapter that comes in the box. If the light is a LED light that doesn’t use a traditional bulb, GE Customer Service chat will send you an adapter that works with any other type of lights for free. I recommend this product highly if you don’t have a neutral wire.

Para focos de LED hay que tomar en cuenta una carga mÃnima de 15 watts de lo contrario los focos LED encienden con un parpadeo constante, por lo que investigue, es un requisito de carga mÃnima recomendado por el fabricante, en mi caso puse un foco fluorescente de 19 Watts en una sección del circuito y las 3 luces LED en serie con el anterior y con esto los LED ya funcionan correctamente.

I was expecting better from GE. The device was easy to install but this is about it. Once installed I had a problem with flashing lights. Not the light on the switch but the ceiling light. Even the bulb adapter couldn’t fix the problem. Turned out that I have to use the exact same brand bulbs (I use LED) on all tree receptacles. I downloaded the software from GE and started the setup. It took forever for the phone to find the switch. Once it did things went well, for the first time at least. Once the switch was connected to the phone things started going stupid. The switch would turn the lights off for a second and then back on. When this happened the first time, the light that surround the switch changed from white to red and stayed red. The light continued to go on and off at regular interval without any input from me. Turning the switch off, waiting a few seconds, and then turning it back on didn’t do anything about the problem. The lights will stay on for a while and then go off for a second and back on again. This process happened 5 times when I was in the room.Trying to get Alexa or Google to control the unit was an exercise in futility at best. The procedure in trying to connect the unit to Google went well until I got to the place where I was asked to enter the login ID and password for the C by GE software. The site boldly refused to accept the login info, claiming that the account did not exist. The box the switch came in does indeed display that it is supposed to work with Google Assistant but getting it to connect with google is an entirely different story.Once the pairing was aborted I needed to reset the switch and start the procedure all over again. This turned out to be nothing short of a nightmare. The phone could not connect to the switch through bluetooth and many reset were required. After many hours of fooling around with this switch I ended out having to completely delete both the room and device from the C by GE app and starting all over again. Eventually I got the switch to be recognised by the C by GE app.Trying to connect the switch to Alexa was no picnic either. The instructions provided by GE were nothing more than totally erroneous. GE must not have been speaking about the same Alexa app that the Google store has because the instructions at the beginning were directing me to steps that were non existent on the app. Through trying various options I ended out where they wanted me to go and got Alexa to recognise the switch.As soon as I get myself a motion sensor switch I will return this one. I grew up trusting GE but not anymore. This item is total junk.

Casi todos tenemos 3 cables, no 4 como en USA. Este apagador funciona también en ventiladores de techo y ahora puedo encenderlo con Alexa. Compré otro adicional al ver lo bien que funciona su app.
