Our take

The KP125M is the plug we’d buy for almost any home. Matter means it moves with you if you change phones or assistants, and the energy readings turn it from a lamp timer into a way to find what’s quietly running up your bill. The only real catch is the 2.4 GHz requirement, which our setup guide solves in minutes.

What we like

  • Matter setup works in every major home app
  • Energy tracking with cost estimates
  • Slim, doesn’t block the second outlet

Watch out for

  • 2.4 GHz Wi-Fi only
  • Apple Home remote control needs a HomePod or Apple TV
  • Costs more than non-Matter Kasa plugs

Skip it if you only use Alexa and never care about energy data. The Amazon Smart Plug is simpler and usually cheaper.
