Wemo Light Switch 3-Way


The Wemo Smart Light Switch allows you to control lights and ceiling fans 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. Now compatible with 3-way light configurations, the Smart Light Switch can be installed almost anywhere. From porch lights to ceiling fans to recessed lighting, it can control nearly anything that a traditional light switch can and only requires one Smart Light Switch per 3-way circuit. 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 home lighting 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 Light Switch 3-Way at the end of a hallway


The Wemo 3-Way Smart Light Switch can replace traditional 3-way switches commonly found in hallways or stairwells, where two switches control the same light. Only one Smart Light Switch is required per 3-way circuit.

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.

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.

Amazon Alexa product line


Wemo works seamlessly with Amazon Alexa to give you hands-free voice control over your lights and devices. Pair Wemo Light Switch with Alexa to switch your lights on and off with just the power of your voice.

the Google Assistant product line


Wemo also works with the Google Assistant, allowing you to control your lights using your Google Home devices, your Android smartphone, or any other device with built-in Google Assistant support. You'll enjoy seamless, intuitive voice control over any light that's connected to Wemo Light Switch.

Apple Homekit product line


Wemo is compatible with Apple HomeKit. You can control your Wemo Light Switch with the Apple Home app and Siri from your iPhone, iPad, Apple Watch, Mac, or HomePod. Turn your lights, ceiling fans, or an entire room on or off using just your voice.

IFTTT product line


"If This, Then That" is a free web-based service that opens up an amazing array of possibilities for your Wemo Light Switch. Visit IFTTT.com to find applets to turn Wemo Light Switch on and off based on real-world events, receive push notifications about light activity, and much more.

Rated 4 out of 5 by from It works as expected Very good technology. Was a little challenging setting it up but overall not that bad. The 3-way switch should have an option to be dimmable.

Rated 5 out of 5 by from Easy to install and setup After reading some reviews I was expecting a little struggle with the wife setup but it was fast and simple. Setting the off /on time with the app was also easy.

Rated 3 out of 5 by from Great hardware, short sighted software. I purchased this light switch for a home where I needed to control the outdoor lights while I'm not there. I was so happy with the light switch I purchased a second one for the same home and an Insight Switch for my primary home. I had very little trouble setting up the WEMO devices...until I realized that the device at my primary home could not be added to my WEMO app since it's on a different network, at a different location. In the case of two different networks, you have to use two different smart phones/tablets with separate apps to access, in this case, two different home networks. It also goes deeper than the WEMO app. This also impacts the Google Home app. The Google Home app only recognizes devices from a single WEMO app at a time. Although Google home offers the ability to create multiple homes and oversee them, the WEMO apps limited ability to juggle multiple networks/homes ultimately limits your ability to do so from a single Google Home account as well. Belkin/WEMO is aware of this, hopefully they fix this issue. It's hard to give the products a solid rating if this seems acceptable to the manufacturer.

Rated 5 out of 5 by from Another Great Device for a Semi-Smart Home I bought a Wemo 3-way switch for my hallway. As it is the darkest part of my house, the hallway light gets used a lot. So I have been waiting for Belkin to advance the technology to make a 3-way switch possible. The Good: installation and WiFi hookup is super easy, as long as you follow the instructions to a t. (I have however installed 6 Wemo light switches in my house, so I have some experience). It works just like you'd expect a Wemo to work, superbly. And it has a cool little light. The Bad: really the only thing bad about it is the delay between the physical button push and the light actually turning on or off. But it's a very short delay, about 1 second, and I have already gotten use to it. Also the app is great most of the time. It's slightly buggy, but still works the vast majority of the time. Overall this is another home rum by Wemo. I look forward to seeing what they come up with next!

Rated 3 out of 5 by from Troubles with switch scheduling It’s ok, very hard to pair with your WiFi, took about an hour to add product and you might get lucky 1-50 times . Be prepared to be frustrated with this product . Once you get it added it’s pretty good. But the App gets whacked out a lot. Need better coding for sure, especially with the scheduling for time on/off Almost impossible to get write
