After spending more than two years testing 41 smart outlets, we're confident that the Wemo Mini is the best smart outlet plug-in adapter for people who want to add remote control and automation to their existing lamps, fans, or other electrical devices. It's the most reliable Wi-Fi smart plug we tested, it's simple to use, and it works with Amazon Alexa, Apple HomeKit, and Google Assistant. The Wemo Mini is the only model that has been rock-solid reliable over long-term use, offers a compact design that won't block both outlets on a wall plate, and supports all the major voice-control platforms. Like most of the smart plug-in switches we tested, the Wemo Mini is easy to set up: Just plug it into an outlet, download an app to your phone, set up the wireless connection, and then control lamps, small appliances, and even higher-draw devices like fans and air conditioners. The Wemo family also includes light switches and dimmers, so it's easy to expand your system. The Lutron Caséta Smart Lighting Lamp Dimmer costs quite a bit more than the Wemo Mini, but it has two outlets, allowing you to control two lamps or strings of lights at once (though not independently).
