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

Rated 5 out of 5 by from Easily reached and reliable I live in a 2 story house and late in the evening my mechanical timers on the first floor turn the table lamp off. Buying a Belmont 3 way switch has enabled me to turn on a ceiling light upstairs remotely so the stairs are lit when I go to bed. The upstairs light is controlled by 3 switches so one of the switches is a 4 way switch. So the circuit has two 3 way switches, one either side of the 4 way switch. I installed one Belkin 3 way switch in place of the existing 3 way switch nearest the light. All switches operate the light as expected and now I can also control the light remotely. Great product. I control the light automatically now with Apple Home

Rated 5 out of 5 by from Installed on a four way circuit... I have this installed in a four way circuit. Remember to follow the instructions and it will work as designed. I would buy one again.

Rated 5 out of 5 by from Amazing and simple I am a smart home junkie and with that I own a few different switches from other manufactures that work with on and off with Alexa and Google Home. This switch works every....single....time. I won't go into too much detail. It was a breeze to install because since it comes with the colored wires that I simply matched to my outlet. Because the wires come from this device, I just had to pop the cap on and voila, that's it - vs. other switches where I have to take the wires, re-twist or shave them and put them into a slot in the switch. Software is very easy to use. You can't possibly mess up installation since the instructions are on target. It has some pretty nice modes and settings for automation after the fact. One mode I really like is auto-off mode. My home is semi automated. I have Amazon Echos AND Google Homes in almost every bedroom. I have wifi bulbs all over the place. Every closet and bathroom has an occupancy/vacancy sensor which turns on when someone goes in, stays on for as long as they're in there and then goes off shortly after they exit. You can't really use an occupancy sensor with a bedroom, well, you can, technically. You can use something that you manually turn on and will stay on for as long as it detects motion and turns off automatically when you leave. I wanted a dimmer for my master bedroom and it's very nice to know that I can enable this sort of behavior with this device when I want it. In a nutshell I'm going to buy more switches for more areas of my home. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Easily Smarten Your Lights! We would constantly forget to turn on the outside lights before leaving for the evening and end up coming home to a dark entry. This smart switch has fixed that once and for all. Got it so we'd have a way to remotely turn these lights on as we realized we forgot to leave them on but was surprised to find the ability to schedule the lights to come on and off. Even better, we are able to schedule it to come on and off based on the daily sunset and sunrise times. This has solved a long standing issue we've had and I've ordered several more of these to address lights on the side and back of our home as well. Installation was relatively easy. It does require a Neutral wire, which we had but being a 3-gang box with multiple switches, the natural wires were joined together. Had to do a little looking and reading but was able to understand how to get the correct neutral wire back to the new switch. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Easy to use, intuitive I received this as a product demo. Very easy to use and setup. Would recommend it highly. Note I have only selected 4 on the reliability scale as it has not been installed for very long. I assume it will be a 5 before long. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Love Wemo I have used Wemo plugs and switches to automate about 50% of our homes lights. The 2-way switches I have purchased have been easy to install and pretty troublefree. The plugs are even easier to install. The simple integration with our Amazon Alexa devices has allowed us to set up automated and voice activated lights. Works great and was easy to do. So when I got the opportunity to try the new 3-way Wemo light switch I jumped at it for a few places where I needed a 3-way. Unfortunately I was unable to get it to work. The instructions indicated it needed 2 "traveler wires" where as my home only had 1 "red" traveler. We have a newer 6 year old home and I think this setup is pretty comon. I tried connecting my single red to each or the "traveler" wires (individually) on the Wemo and neither worked. After a few tries I was able to get the Switch to be recognized by the Wemo app but it would not power on the lights unless I used the other manual switch on the curcuit. Withon the app was a form to submit if you had an issues and I did request help but never got a response. I hope to be able to get a hold of someone in support to get this resolved but have not been able to yet. [This review was collected as part of a promotion.]
