This smart plug also dims a lamp, and it’s 25% off for Black Friday

Smart plugs come in two categories: on/off devices that can control lamps as well as small appliances, fans, and space heaters, and dimmers that control a lamp’s brightness as well as turn it on and off. Leviton makes some of our favorites in both categories, and Amazon has knocked 25 percent off the price of the Leviton Decora Smart Dimmer Plug, bringing its final price down to just $18.74.

Beyond its excellent build quality, this smart dimmer is particularly appealing because it can also be controlled by Leviton’s Decora Smart Dimmer Companion to create a wireless 3-way circuit. So, not only can you control the plug with Leviton’s app on your smartphone—or create a schedule for it to operate on—but you can also use Leviton’s Dimmer Companion (which gets a 9-percent discount for Black Friday) as a physical remote control.

Most people mount this second device to a wall on the other side of the room or at the end of a hallway or stairway; the remote has a range of 50 feet. Used this way, the battery-powered Companion looks just like a hardwired in-wall switch, complete with a trim plate.

The Decora Smart Dimmer Plug connects to your Wi-Fi network, eliminating the need for a smart home hub or bridge, and it can also be controlled with voice commands from Alexa, Gemini, or Siri.

And if you’re looking for a smart plug to control your outdoor holiday lights this season, Amazon has also knocked 25 percent off the price of the Leviton Decora Smart Wi-Fi Outdoor Plug, bringing its price down to $37.60. It has all the same smart features, and it can be remotely controlled with the wireless Decora Smart Switch Anywhere Companion.
