Hi, daniel. The Wemo Light Switch (WLS040) allows you to control lights that are wired to the same circuit with the Wemo Light switch.

Will this switch work with a motor?

Answer

Hi, SausageKig03. The setup has not been tested, however, it may work if the wiring is properly connected and if the fan do not exceed the maximum wattage. Moreover, the speed won’t be controlled.

Just buy a regular light switch instead
I bought a couple of these for use as IFTTT wall controllers (controlling several WiZ lights), but their response time is so slow that it's basically unusable. On average, it took between 30 to 60 seconds for my lights to turn on after I pressed the switch, and that's with a very good home WiFi system. Note that I was not using the switch itself to provide power to the lights (just cap the red wire off, it works fine), but rather had them send a command to smart lights through IFTTT so I could trigger different color scenes. Even if you intend to use them as normal smart switches, the WeMo app has a horrible user interface that allows for very little scene / whole home control. I would strongly recommend Leviton's Wi-Fi switches over these, as their IFTTT response time is a few seconds at most. Not to mention, their app is vastly superior to the WeMo app.

Customer review from belkin.com logo
Nice switch but if you're installing 3 switches Wemo should make cover plates for 2 and 3 switches.

Great Smart Home Addition!
Customer review from belkin.com logo
The Wemo Smart Light Switch is a great addition to any home's smart technology network. I used these switches for exterior lighting that I wanted to control with a nightly schedule and they work perfect. The switch looks grest and was fairly easy to install. The only downside to this product that kept it from a five star rating was the App setup process. I'm consider myself to have intermediate technology skillls and connecting this product to my network took quite a bit of effort that was not explained in the user manual. However, once connected to my network the App is easy to use and setup.

Adding another switch
Customer review from belkin.com logo
Couldn’t tell between this one and the older single poke light switch so I chose this one. I works the same as my other 15 that I have in my house. [This review was collected as part of a promotion.]

Love my Wemo devices!
Customer review from belkin.com logo
I have single pole switches, dimmers, and 3-way switches as well as receptacles from Wemo and I am extremely happy with them all. If you want something that’s plug-and-play then this is it. As long as your wifi signal is good you don’t need a hub or anything. Setup on the app to set timers for sunrise, sunset, or any time between is simple even without HomeKit, Alexa, or Google home (which I also have so voice control is easy too). Worth the money compared to some cheaper versions which do less.

Awesome product
Customer review from belkin.com logo
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.

Unreliable_Horrible_always needs to ne reset
I have had two wemo light switches FOR A FEW YEARS. Since earlier this year whenever there is a power outage and it loses connectivity with its access point it will never re-establish a connection. It has to be reset EVERY TIME. Just a horrible product. The technology in this has to be from 2004. Straight garbage. I have an enterprise network setup and these wemos never maintain a connection after any kind of disruption. I upgrade the firmware on one access point migrate connections over to another access point but wemo nope. Always needs to be reset. Just a garbage product. Horrible code. WEMO Fix the reliability of you smart offerings. Im jumping ship off of these devices.

Works well enough. They tend to go off line often...
Works well enough. They tend to go off line often and I have had to reset it a couple times now within the last two months. Other than that, no complaints.

You might want to check if the switch is running on the latest firmware and if it gets a stable connection from the router.

Version 2 Products are GREAT!
Customer review from belkin.com logo
The version 2 of the WEMO products make it much easier to install and manage the switches. I am thankful that I can install and manage switches from different locations. The integration with HomeKit and Alezia is also better.
