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 1 out of 5 by from Don’t buy these I bought a two pack from Wemo’s website. I have had them for over a year. They are horrible and constantly freeze. It is not a connection issue. They freeze and must be reset, but I can only reset them by flipping the breaker. I just changed over to the Kasa switch and so far so much better and they are cheaper and easier to set up. I have spoken to Wemo support on multiple occasions and spent hours on the phone with them. They even sent me a new one which I changed out and sent the old one back. Same issue with the new one. I have had the plugs for years and have liked them well enough. Now the app won’t work, the switches keep freezing and I am now trying out the Kasa plugs and switches. Don’t buy these.

Rated 5 out of 5 by from Smart 3-way switch Belkin has come along way with their products. It used to take hours trying to install/configure to my WiFi network, then have to call support for assistance. I wouldn’t even dare add those devices to my Apple Home. Now, it’s amazingly simple. It practically installs itself. Very satisfied.

Rated 1 out of 5 by from Horrible connectivity problems - not recommended I purchased four of these and had them professionally installed by an electrician. Three of four are always showing offline, one can be controlled in the app but not at the wall, and the fourth works as designed. Keep top of mind this is in a house with over five years where many Wemo switches and plugs have been in use without issue, including a non-3 way Wemo switch controlling the front door lighting. No changes have happened in router setup or wireless network settings. When they don't work, you cannot turn on or off the light using the Wemo physical switch. You are then forced to use the 2nd switch assuming you installed this on a shared connection. This product is just not ready for market.

Rated 4 out of 5 by from Very happy once setup. Very happy with switch once I got it setup. The wiring was a little difficult for me because of several circuits within the box. I wanted to be able to use the switch with my Alexa and to be able to have the lights turn on and off on a schedule. I found the manual very limited as to how to set this up. And I found the Belkin tech support unhelpful and the technician hung up on me. I finally found very good step by step help on YouTube.

Rated 1 out of 5 by from Continually goes through reset cycle. Won't allow When initially installed, worked fine for a week or two. After an firmware update or two, started to flash red and white blinky lights and occasionally would stop responding to manual activation. Got so frustrated, removed the 3 ways. Is this product too immature?

Rated 1 out of 5 by from Newer home, no neutral My home was built in 2004 but does not have neutral wire so product does not work.

Rated 5 out of 5 by from Easy to install and set up I bought this to help grow my Homekit setup, I've had a Kasa switch in the box for quite a while and hadn't installed because it wouldn't connect to Homekit. I installed this 3 way switch and a regular Wemo switch in a matter of minutes for each. The instructions are very clear and setup once installed is quick and easy. Now that we've installed these two switches we may install more around the house.
