Leviton Decora Smart Wi-fi Plug-in Dimmer

Leviton's Wi-Fi smart plug works perfectly with Alexa and Google Assistant, and you don't need a hub in order to use it. The slim-bodied design won't block adjacent outlets after you've plugged it in.

The plug doesn't work with Apple HomeKit, so you can't control it with Siri, and it won't track energy usage. It also doesn't include any USB charge ports.

This is a basic, no-fuss smart plug from an established manufacturer that gets the job done without costing too much.

The Decora plug-in dimmer is easy to use, and it works well with Alexa to let you dim your lamps up and down using voice commands. The My Leviton app is well-designed, with plenty of controls for automating your lights or customizing things like fade...

The dimmer's bulky design blocks off any outlets below it, and you'll need to plug your lamp into the bottom of the device, which can be a little awkward. There also aren't any significant third-party integrations beyond Alexa.

This Alexa-compatible plug-in smart dimmer gets the job done, but alternatives from Belkin, Lifx, and Philips Hue are all more fully featured, and more cost effective, too.
