Higher ratedRanked #1 in Best Smart Plugs

Kasa Matter Smart Plug KP125M

4.7

$25.99as of Jun 7

The KP125M is our best-overall smart plug: it pairs TP-Link's first Matter-certified plug with genuine energy monitoring and a slim profile that doesn't block adjacent outlets. Reviewed named it their Editor's Choice best-overall pick, and both Engadget and CNN Underscored picked it as the best Matter plug. The trade-offs are minor: multipack-only availability and Wi-Fi (not Thread) connectivity.

Strengths

— Matter-certified, so it works natively with Apple Home, Alexa, Google Home, and SmartThings
— Built-in energy monitoring tracks real-time and historical wattage per device
— Compact slim body lets two plugs share a standard duplex outlet

Watch-outs

— Only sold in 2-packs and 4-packs, not as a single unit
— 2.4GHz Wi-Fi only, no Thread radio for mesh networking
— HomeKit connectivity can be spotty without an Apple home hub

— Excellent value — among the cheapest Matter-certified plugs

Watch-outs

How they stack up

Kasa Matter Smart Plug KP125M

The best all-rounder of the group. Unlike the Tapo P125M, it adds energy monitoring; unlike the Wyze Plug, it carries Matter certification for cross-ecosystem use; and unlike the Wemo Smart Plug with Thread, it isn't locked to Apple Home.

TP-Link Tapo P125M

The budget Matter alternative to the Kasa Matter Smart Plug KP125M — it drops the KP125M's energy monitoring to hit a lower price. It carries the Matter certification the Wyze Plug and Amazon Smart Plug lack, and unlike the Wemo Smart Plug with Thread it isn't tied to Apple Home.
