After testing more than a dozen models, Engadget found the Kasa Smart Plug Mini EP25 to be the best overall smart plug for 2026. It costs about $13 each, works reliably with all major platforms (Alexa, Google, Siri, SmartThings), and offers a stable connection without requiring a hub. Its straightforward setup and consistent performance beat out competitors with more quirks.

Compatibility is the primary consideration. Most plugs use Wi-Fi, but the new Matter standard aims to fix cross-brand issues. The Kasa Matter Plug (KP125M) is the top Matter option, though some HomeKit integrations remain finicky. Users must match plugs to their preferred ecosystem—Amazon’s plug is dead simple for Alexa homes but locks you into that app, while Apple’s HomeKit requires a permanent HomePod or Apple TV for remote access.

Setup usually involves a manufacturer’s app to connect to Wi-Fi, often using Bluetooth for initial pairing. Sharing control with family is easiest via Google Home or Apple’s HomeKit; Amazon’s Alexa app doesn’t share device control at all. For those building a large system, hub-dependent brands like Aqara can reduce Wi-Fi congestion but add cost and complexity. Choose a plug that matches your existing smart home setup for the smoothest experience.
