Limited third-party integrations
With the Ezviz T30-10B Smart Plug ($19.99), you can turn ordinary electronics into smart home devices that you can control with your phone or with your voice. This slim single-outlet smart plug won't block access to a second receptacle and is easy to install. It also supports Amazon Alexa and Google Assistant voice control and can tell you how much power you're using. That said, it costs more than twice as much as our more versatile Editors’ Choice award winner, the Wyze Plug, which comes in a pack of two for $14.99.
A Slim Design
Intended for indoor use, the T30-10B is a single-outlet plug that measures 1.5 by 3.1 by 1.2 inches (HWD) and is short enough to use in a two-outlet receptacle without blocking access to the second outlet. It has a single three-prong outlet on the front, along with a backlit on/off button, and around back is a three-prong plug. The button glows solid blue when the plug is on, rapidly flashes blue during setup, and slowly flashes blue when disconnected from the network. Under the hood is a 2.4GHz Wi-Fi radio for connecting to your home network.
