Smart Plugs / TP-Link
Kasa Matter Smart Plug KP125M (KP125MP4 4-Pack)
Matter done properly — except the energy monitoring never leaves the Kasa app.
Overall score 8/10
Pros
- + Matter multi-admin means the same plug can live in Apple Home and Alexa simultaneously — the Kasa EP25 cannot
- + Matter on/off is handled locally, so it survives an internet outage
- + Street price has fallen to roughly half the $69.99 launch MSRP for the 4-pack
- + 2-year warranty and UL certification
Cons
- − The headline energy monitoring is invisible over Matter — you must install the Kasa app alongside your chosen platform to see a single watt
- − TP-Link does not publish a motor/HP rating for this model, so inductive loads are a guess
- − Needs a Matter controller you may not own; the plug alone does nothing in Apple Home without a HomePod or Apple TV
- − Amazon 4-pack pricing swings between roughly $37 and $43, so per-unit comparisons against 2-packs are unstable
Kasa Matter Smart Plug KP125M (KP125MP4 4-Pack) review: what the specs say
Matter done properly — except the energy monitoring never leaves the Kasa app. At $37.93, TP-Link's 2023 model sits in the middle of the range — the smart Plugs we compare run from $11.99 to $52.99. It scores 8.0/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Ecosystem Support at 9.0/10 — matter, HomeKit, Alexa, Google, SmartThings and Home Assistant coverage. The weakest is Load Headroom at 4.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: the headline energy monitoring is invisible over Matter — you must install the Kasa app alongside your chosen platform to see a single watt; and TP-Link does not publish a motor/HP rating for this model, so inductive loads are a guess. Every specification on this page comes from TP-Link's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
