Most compact Matter smart plug with energy monitoring — leaves the adjacent outlet fully clear

TP-Link KP125M: Compact Matter plug that leaves both outlets usable

The KP125M is functionally similar to the Kasa EP25 — same TP-Link/Kasa ecosystem, same Matter certification, same energy monitoring — in a smaller body that clears the adjacent outlet. If outlet space is constrained, that difference is meaningful.

What works

Compact design is the headline. Where the EP25 protrudes far enough to sometimes cover adjacent sockets, the KP125M stays within the bounds of a single outlet position. In tight power strips or double-outlet wall plates, this is the difference between using both outlets or not.

Matter certification provides the same ecosystem-agnostic compatibility as the EP25: Alexa, Google Home, Apple HomeKit, SmartThings all work simultaneously. Energy monitoring is included at $18 — the lowest price for a Matter-certified monitoring plug in the category.

What doesn't

The KP125M's app experience is more limited than the EP25, with fewer energy visualization options and less detailed usage history. A firmware update is required on first connection, which adds 5-10 minutes to initial setup. Not a dealbreaker, but worth knowing if you want instant out-of-box function.

Who should buy this

Anyone in a space-constrained outlet situation who needs Matter and energy monitoring. Also the best entry price for Matter hardware if features beyond basic control aren't the priority.

Who should look elsewhere

Full-featured energy monitoring app: Kasa EP25 ($22). Apple HomeKit-only households without outlet constraints: Wemo Mini 2nd Gen ($35). Budget monitoring without Matter: Emporia Smart Plug ($20).
