Smart plugs are the easiest entry point to a smart home. You don’t need a hub for most of them, you don’t need to rewire anything, and the good ones cost less than a pizza. We rounded up 5 picks that punch above their price tag, all under $20, all on Amazon right now.

One thing to know before you buy. If you’re already running a HomeKit, Alexa, or Google Home setup, double-check the compatibility on each plug. Some only work with one ecosystem. The picks below cover most of the main ones.

Alexa Optimized Easy Setup Routines

If you already have an Echo, this is basically plug and play. No separate app to download, no QR code dance. The catch is it only works with Alexa, so skip it if you’re a Google or Apple user.

Wyze sells two of these for about $14, which is borderline absurd. Build quality is what youd expect at this price, but they work, the app is decent, and Alexa/Google integration is rock solid. A great way to dip a toe in without spending much.

What to Look For in a Smart Plug

Three things. Whether it needs a hub (most under $20 don’t), what ecosystems it works with, and the amperage rating. 15A is standard and handles most household stuff. If you’re plugging in something serious like a space heater or window AC, double check that the plug can handle the wattage.

Also worth knowing, most cheap smart plugs are 2.4 GHz WiFi only. They won’t connect to a 5 GHz only network. If you’ve split your bands or you’re on a mesh router, make sure to enable 2.4 GHz before setup.
