The KP125M takes best-overall smart plug: 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 Engadget named it their Best Matter Plug. The trade-offs are minor: multipack-only availability and Wi-Fi rather than 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
Wemo Smart Plug with Thread
Ranked #2 in Best Smart Plugs
Wemo Smart Plug with Thread
2 sources$27.99as of Oct 16

The Wemo Smart Plug with Thread suits Apple HomeKit homes building a Thread mesh: it pairs with an NFC tap and strengthens a low-latency Thread network. PCWorld confirms it as a HomeKit-only device. That limit is significant. It works with Apple Home and nothing else, so no Alexa, no Google.

Strengths
  • — Touchless NFC pairing: tap an iPhone to set it up in seconds
  • — Acts as a Thread border-router extender for an Apple Home mesh
  • — Premium build quality from Belkin's Wemo line
Watch-outs
  • — Apple HomeKit only — no Alexa or Google Assistant support
  • — Cannot be controlled from the Wemo app, only Apple Home
  • — Thread setup introduces a few limitations versus plain Wi-Fi

How they stack up

Kasa Matter Smart Plug KP125M

Unlike the Wyze Plug, the Kasa Matter Smart Plug KP125M carries Matter certification for cross-ecosystem use, and unlike the Wemo Smart Plug with Thread it is not limited to Apple Home. It has energy monitoring, which the Amazon Smart Plug, the Wemo and the Wyze Plug do not. It connects over 2.4GHz Wi-Fi and has no Thread radio, which the Wemo is built on.

Wemo Smart Plug with Thread

The Wemo Smart Plug with Thread is the only Thread plug here, and it works with Apple Home alone. Where the Amazon Smart Plug is Alexa-only and the Wyze Plug covers Alexa and Google Assistant, the Wemo extends a Thread mesh, which the Wi-Fi-based Kasa Matter Smart Plug KP125M cannot do because it has no Thread radio. It needs an Apple home hub or Thread border router, while the other three need no hub.
