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
Meross Matter Smart Plug with Energy Monitor MSS315 (4-Pack)
Pros
- +One of the few Matter plugs that meters power and is sold in a four-pack
- +Physically the least intrusive of the metered Matter plugs — it genuinely does not block the second socket
- +Matter multi-admin, so it can sit in Apple Home and Alexa at the same time
- +Popular with Home Assistant users thanks to an active community integration
Cons
- −$13.25 a plug at Meross's own store price — 60% more than a Kasa EP25 for the same job plus Matter
- −Meross explicitly requires a Matter-compatible hub and an IPv6-capable network; a bare phone will not do
- −No published motor or HP rating, so inductive loads are unspecified
- −1-year warranty against TP-Link's two
- −Amazon four-pack pricing moves independently of the Meross store price, so per-unit maths depends on where you buy
