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
