Best overall smart plug: Kasa Matter Smart Plug KP125M (2-pack)
Matter. You add the KP125M to your home app by scanning its code, and it can be shared with several platforms at once. If you move from iPhone to Android, or add a SmartThings hub, the plug keeps working without the Kasa app in the middle.
- Matter setup works in every major home app
- Energy tracking with cost estimates
- Slim, doesn’t block the second outlet
- 2.4 GHz Wi-Fi only
- Apple Home remote control needs a HomePod or Apple TV
Skip it if you only use Alexa and never care about energy data. The Amazon Smart Plug is simpler and usually cheaper.
Best value multi-pack: Kasa Smart Plug Mini EP25 (4-pack)
The EP25 already supports Apple HomeKit, Alexa, Google Assistant and SmartThings directly, and it’s cheaper per plug, especially in the four-pack. Engadget named it the best smart plug overall (February 2026). For lamps on schedules, it does everything most people need.
- Very low cost per plug
- Works with Apple HomeKit, Alexa, Google and SmartThings
- Energy monitoring included
- No Matter
- 2.4 GHz only
Skip it if you want a device that will work with any future platform. Pay a little more for the Matter KP125M.
