These well-rated smart plugs are compatible with voice assistants like Amazon Alexa or Google Assistant. The Aukey Home app, which is free to download, lets you activate and deactivate home appliances and electronics from anywhere in the world. Automatically turn on your lights when the sun sets, flip them on and off at random intervals when you're on vacation, schedule your coffee timer to go off, or use your voice to turn off the box fan that keeps lulling you back to sleep. You don't need a bridge, hub, dongle, or anything else to make them work. Just a Wi-Fi network.

Aukey's smart plugs will raise your home's IQ without putting a huge dent in your bank account. As an added bonus, they're compact, so adjacent outlets will stay usable. Your purchase includes a 24-month warranty as well.
