  • YoLink Hub or SpeakerHub (audio, talking hub) with an internet connection (wired Ethernet or 2.4GHz Wi-Fi). Refer to the hub user guide for additional information
  • Smartphone or tablet running iOS 9 or higher, Android 4.4 or higher
For full functionality, including for the app to work, YoLink devices must connect to at least one hub (YoLink Hub or SpeakerHub), and that hub must have an internet connection. Unless you are adding devices to an existing YoLink account, or unless your building is covered by an existing YoLink wireless network, please add one hub to your order.

Do Try This at Home!

Consider automating your lights, to add safety, convenience, and even savings on your power bills! Turns lights on automatically, hands-free, when you enter a room. Turn them off, or set them to a lower level, when no motion is detected in the room. 

Set up lighting scenes, that allow you to control lighting in one or multiple rooms at the same time, even all indoor and outdoor lighting - set automatically to your preferred power setting (off, or on: 1 to 100%).

Yolink Dimmer Switch

I added 3 Dimmer Switches to control 7 various external LEDs (100W incandescent equivalents). They work perfectly and are programmable within the YoLink environment and (untested by me) probably other/3rd party home automation ecosystems. They are a perfect complement to YoLink motion detectors, door open sensors, etc. when used in YoLink Automations and Scenes (and thus probably 3rd party integrated-ecosystems/scripts). Happy here.


WOW WOW WOW!!! After dealing with disconnect after disconnect on a previous brand dimmer switches, whos brand I will not mention. These have been absolutely the best dimmer switches ever.
Never go off line and have amazing operating selections through the app.
Work very well with Alexa. I have three.

Best dimmer switch available.

I just put 3 of them in my house.

Poor design

Ground wire on wrong side of metal. Apparently, YoSmart aware of this and now changing manufacturing, but should have alerted me to this prior to my purchasing or recalled dimmers or at least provided instructions on now to "get around" this issue.

Replaced Cassetta dimmer that would flicker

Works perfect. Simple install and very easy to control with Alexa.
