Wemo Light Switch


The Wemo Smart Light Switch allows you to control your lights from the wall, the Wemo app, or with your voice*. 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. Whether you're unwinding on the couch, working at a coffee shop, or vacationing in the Caribbean, you'll be able to remotely control your lights from anywhere.

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.

Wemo App with Multiple Wemo devices listed


Wemo gives you another level of control over your Wemo devices with its long-press feature. You can group multiple Wemo devices together and turn everything on or off with a single 2-second press on your Wemo Light Switch.

Unoccupied house with lights on at night


With the ability to randomize your lights, Wemo Light Switch protects your home better than a mechanical timer. When set to "Away Mode," Light Switch will turn lights on and off randomly to make it appear like you're home – even when you're not.

Rated 4 out of 5 by from Love It ... but ... I've had the switch for several weeks and it has operated well. The drawbacks are that it will not stay connected to the WEMO App, but if you have it connected to a Google device, you can still control it which shows to me that it is a problem with the WEMO app. I have other devices that are occasionally not connected, but I can unplug them to get them to reconnect. That is not as easy with the switches. Installation is easy. As others have said, setup is a nightmare. It wants to connect to Apple Home before connecting to the WEMO app. So, it will not show up in the WEMO app. I will say, once you get it setup, it operates as expected and if you can overcome these small drawbacks, you can use it well.

Rated 2 out of 5 by from Don’t buy this one . Buy the pricer Wemo switch This switch is garage .. be prepared to remane your product and try to add /pair for at least an hour. Step up and pay the extra 10$ for the other switch. Which they don’t tell you the difference between the two. Trust me abd go With the more expensive Wemo switch . Easier to pair and works better

Rated 5 out of 5 by from Works with integrated LED light I just had my handyman install the Wemo smart light switch, and it works perfectly on my outdoor LED light. Years prior, I had installed a timer switch for this same light, but the amperage of the integrated LED was insufficient for that switch to work. I set the Wemo switch for dusk to dawn and it worked immediately. I have two Wemo plugs in the house and love the Wemo/Echo infrastructure.

Rated 4 out of 5 by from Easy to install Installed this about a week ago and I'm happy with it. Wanted to be able to set up a timer for my front porch and outside garage lights so I replaced the standard light switch and I couldn't be happier, it was real easy to set up the feature to turn on at sunset and off at my desired time.

Rated 4 out of 5 by from Great Overall Value I just put in (3) light switches in the garage. The worse place in the house where everyone forgets to turn the outside lights on/off. Now they are on a schedule and the internal and spotlights are accessible from anywhere. The only reason I did not give 5-stars is the documentation and setup is a little kludgey. HomeKit didn't see the switch and the links in the app that go to the Belkin website go no where. Being technical, I figured it all out. Plus the three switches I replaced were wired in series, once I figures out Line vs. Load everything fell into place. I will be adding more throughout the house, may even put in a separate wifi network just for the automation stuff.

Rated 4 out of 5 by from WEMO Light Switch I like the new light switch because it is Alexa enabled. This allow me to learn more about Alexa interaction between other home devices. I was able to schedule times to turn on and off my outside lights through my new Wemo switch for security purposes. Especially when I am away from home. Good job.

Rated 5 out of 5 by from Awesome product I bought this a week ago to control my front porch light. Super easy to wire and love the feature where you can set a rule to turn on and off with sunrise and sunset.

Rated 4 out of 5 by from Good stuff. The only difference that I wanted , was for it to work with my Apple home app so I could tell seri to turn it on with my voice. I was waiting for a software update that would make my old one work with Apple home app . But it never happened. So out with the old in with the new.
