This smart light switch connects to your existing home WiFi network to provide wireless control of your lights – with no subscription or hub required. From porch lights to ceiling fans to recessed lighting, Wemo Light Switch can control nearly anything that a traditional light switch can.

Home with all the lights on while the sun is rising


Wemo Light Switch lets you easily set automatic schedules for any light. Using the free Wemo App, you can schedule your lights to turn off at sunrise, or synchronize your porch light with the sunset so you never come home to a dark house.

Rated 2 out of 5 by from Worked for two days and died I have other wemo switches (v1 and dimmer) that have been working well for over a year. I bought the new version 2 switch and it died in two days and will not operate at all. A replacement is on its way and I hope I have better luck with it.

Rated 5 out of 5 by from Easy to install, works with many Apps... The installation instructions were very well written, easy to follow and set up the switch. It's nice that it works with Apple HomeKit and other systems (like Alexa), as well as being able to shut off remote access. The only glitch was I initially tried to set it up using an old iPad (the iOS version was too old), worked great on my newer iPhone. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Nifty gadget! Turning on and off exterior lights is great with this switch and timer. It has a sundown/sunrise selection based on zip code. Having it connect to an app on my phone and Amazon Alexa is really nice. Just what I needed.

Rated 4 out of 5 by from Cool switch, but needs planning on installation The WEMO Smart Light Switch is a nicely put together product with lots of useful integration features. Along with the usual integration partners, it's nice to see IFTTT (If This Then That) support that allows to to do some really oddball things if you like. The installation goes pretty smooth if you know your way around basic home wiring, and the provided instructions are very well done. Adding in the wire nuts needed is a nice touch as well for those that don't have this stuff handy. The configuration app worked well on Android, and has vastly improved from earlier WEMO products I have used. With the current app I had no problems getting the switch online and working on my wireless LAN. I had all kinds of issues with doing this for a WEMO smart plug receptacle a while back, so it's nice to see this working properly now. My only complaints are that the portion of the switch that fits into your existing wall box is kind of large, and this makes it somewhat difficult to shove the switch and the wiring back into it. Also, using the switch in an existing multi-gang wall box (IE: 2 or more light switches with a common cover plate) is a challenge if you have the older style flip switches I have in my home. With the Smart Switch using the newer form factor, you will need to purchase a cover plate that combines the old and new style switch cutouts in the locations you need them, or change out all the other "dumb" switches in the multi-gang box to the new style and use the easily found new style covers. All in all, a great little smart switch that I am enjoying using [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great product, easy setup I got the Wemo single pole light switch a few weeks ago and have been using it now for about a week. So far I'm very happy. The first thing I noticed when opening the box was that there weren't a lot of parts: a switch and face plate, 4 wire nuts and an installation guide is all there is. I did need to obtain a Phillips and Standard screw driver, as well as a voltage tester, though. The installation of this switch was as easy as replacing an existing single pole switch. It took about 15 minutes for me to unbox the switch, install it and set a basic program. A majority of that time was spent trying to locate the correct circuit breaker for the switch I was replacing. The back of the wemo switch had nice color coded wires along with labels to easily guide you when installing to your existing wiring. However, I did have to look up the difference between "line" and "load" wires as not all of my switches are wired the same. Once I figured that out though it was a matter of disconnecting my line, load and ground wires from my old switch and then reconnecting my existing line, load, ground and neutral wires via wire nuts to the new wemo switch. After the switch was installed and power was turned on it began blinking and I installed the Wemo App onto my phone. While using the App I was able to quickly and easily set up my wemo switch and add a few "rules". Rules is there term for programming. Some of the basic features include: Schedule, Auto-off timer, Long Press, Motion Detector, Away Mode, Motion Alerts and Usage Alerts (some of these features require additional products in order to use them). I set a basic on/off schedule and also the auto timer to turn the light off after a few minutes to simulate someone is home. I really liked that the light switch has a modern look to it and it can still be used like a normal light switch to turn the lights on and off. In addition, I can use the App to turn the light on/off without getting up or going to the room if so inclined. So far I am really impressed with the switch, the easy setup and the amount of features it has. I may have to add some additional 3-way switches in the near future since that is what most of my home contains. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Lots of features, easy setup I got this Wemo single-pole light switch a few weeks ago. The installation was very simple and quick. Probably took 15 min from the time I opened the box to it being installed and programmed. Finding the correct circuit breaker for the switch was the hardest part. Only tools I needed was a voltage tester and a screw driver. Wires were clearly labeled and color coded making the connection to my existing wiring easy. I did have to look up what the difference was between “line” and “load” wires though. After installation I programmed the switch to a schedule I wanted for the room and it’s been working well so far. The switch can also be easily used as a regular light switch or I can use the Wemo App on my phone to turn the switch on/off or to adjust the settings. The App is easy to use and offers many useable features, which I am still exploring. After using the single pole switch I will probably be buying additional 3-way switches for other areas of my home. Great product that I like so far. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Simple to install and setup! I was afraid I would need to hire an electrician to install this switch, but the instructions were so clear and simple I was able to install it myself in less than 5 minutes. The installation guide is amazing. Compliments to the writers. Having one page per step makes it simple to install this switch. Once the switch was connected to power the remaining setup was very easy also. The features on the Wemo app are very intuitive and easy to program. Great product!
