Pros & Cons
Kasa Smart Plug Mini EP25 (EP25P4 4-Pack)
Pros
- +Roughly $8 a plug with real measured energy monitoring — nothing else here is close on price-per-watt-meter
- +Native HomeKit, so Apple users do not need a Matter controller or a Thread border router
- +LAN control means schedules keep running through an internet outage
- +2-year warranty, double the 1 year Wyze, Eve, Emporia and SwitchBot give
Cons
- −1/6 HP motor rating — fine for lamps and fans, not for a compressor, pump or shop vac
- −1,800W resistive means a 1,500W space heater sits at 83% of rating continuously; TP-Link does not endorse heater use
- −No Matter, so it cannot be shared into SmartThings or Google as a Matter device
- −TP-Link's current 4-pack listing title dropped the 'with Energy Monitoring' wording the 2022 launch press release used, and Home Assistant users report the newer hardware revision reports 7-day/30-day totals instead of lifetime kWh
Kasa Matter Smart Plug KP125M (KP125MP4 4-Pack)
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
