Wemo WiFi Smart Dimmer Product Shot


Wemo WiFi Smart Dimmer gives you total control over your lights with no subscription or hub required. Easily set the ambiance of any room and control lights from the Dimmer, the app or with your voice. From bedroom lights and dining room chandeliers to recessed lighting, Wemo Dimmer can control nearly anything—just like a traditional dimmer switch, but better. Whether you’re relaxing on the couch, working from the home office, or traveling, it’s a breeze to control and dim your home lighting.

Wemo Dimmer App Schedule


Wemo Dimmer lets you easily set automatic schedules for any light. Using the free Wemo app, you can schedule your hall lights to turn off at sunrise or synchronize your living room lights with the sunset so you never come home to a dark house.


Want to minimize bright-light blinding when you’re getting a midnight snack or checking in on the kids? With Night Mode, you can set your Wemo Dimmer to turn on to a lower light level during specific times.

Wemo Dimmer will calibrate to work with your specific type of bulb – from LEDs and CFLs to incandescent bulbs. No matter what type of bulb you’re using, you’ll enjoy the maximum amount of dimming range with no flickering.

With the ability to randomize your lights, Wemo Dimmer protects your home better than a mechanical timer. Away Mode randomizes lights for added home security—it’ll look like you’re home even when you’re not.


Your Wemo Dimmer can do so much more than dim. With the Long Press feature, you can set any number of other Wemo devices to respond to a two-second press of the Dimmer button. You can use Long Press to turn all Wemo lights and devices on or off. Or put all your Wemo lights into Away Mode when you leave for vacation.

Rated 5 out of 5 by from Great Dimmer This is an excellent accessory to have in your home! It works great with Siri when responding to voice commands. installation and set up was easy to understand when following the installation manual. However, I was limited to the type of switch I could use this on. It would be nice to have a switch that could work with two way switches. The instructions were great, but if you’re not comfortable installing this item on your own you can always get an electrician. I was provided this product for free to try it in my own home, for my own honest review. I would recommend this accessory for anyone looking for a dimmer switch.

Rated 1 out of 5 by from Horrible app. Only work intermittently These have the most horrible Android app, both for installation and for use. Physical installation was clear - great instructions. Setup using the Android app was a frustrating and complicated process. Did three of these in a row. Ended up having to force stop and clear cache between each setup. Now that they are set up they only occasionally show up and work in the app. Trying to use a Google Assistant routine or command only works about fifty percent of the time. Been installed three days and I've had to press the reset button on each switch (flashing red lights) at least once if not twice since installation.

Rated 2 out of 5 by from Needs improvement I am one of those shoppers that hardly ever writes reviews, but does read them 80% of the time before making a purchase. The attached screenshots will explain my review. I bought two smart dimmers a couple years ago. As with all Wi-Fi devices there will always be connectivity issues. However with all the Wi-Fi devices in my home, these two dimmer switches are the only devices that randomly will not be connected when I want to switch/fade from the app (the actual switch at wall always responds). One week (time period is random for both), one switch will be grayed out, & app will ask if I wish to hide button. The next week, the other switch will do the same, while I am able to use the other. My WEMO smart plug that I have owed for probably 3-4 years has never given me the sort of trouble.

Rated 5 out of 5 by from Easy Install and Integration Usually I let my dad, who knows way more about electrical work than I do, install these types of products. I decided to give this one a shot on my own and it was incredibly easy to do with a step by step walkthrough in the application. Once installed, the app elegantly walked me through getting the switch on the network and testing the bulb types and dimming capabilities. From there I easily integrated the smart dimmer with both Alexa and Apple HomeKit. Setting up routines for dimming at certain times of the day could not have been easier. Highly recommended.

Rated 5 out of 5 by from Looks and works great!!! All I can say is wow!!! I was a little concerned about not really the physical installation of this switch but mainly getting it synced up with the app and Wi-Fi. First off, the set up is AWESOME.....I know it is just a setup guide however this one is very legible, colored pics and very easy to understand. After installing, adding the Wemo app and setting up the switch was flawless and just as easy. It allows you to actually calibrate you light, which I needed with my LED bulbs, to work beautifully. This setup was so easy that I went ahead and added to my Google Assistant as well. It looks very nice and modern and works just as well. I would definitely recommend and look forward to adding more Wemo products in the future.

Rated 1 out of 5 by from No longer pairs with Alexa My dimmer never worked well. Several times the switch was stuck and could not turn off or on unless I went to the breaker box and turned the power off. Recently, the switch lost pairing with Alex. Alexa no longer recognizes/connects to the dimmer switch.

Rated 5 out of 5 by from Wemo Dimmers Works very well! Purchased 3 dimmers last year. Purchased 2 more to have complete control over lighting levels in great room and upper level balconies. Would buy additional units if compatible with 3-way circuit.

Rated 5 out of 5 by from Great Addition Great addition to our dining room. Easy to install, yet the HomeKit Code should be on packaging (as well as unit itself). Avoid having to take things apart to get to code when installing.
