Pros & Cons
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
Eve Energy (Matter, US)
Pros
- +The only genuinely cloud-free plug here — no account, no registration, no telemetry, and the energy history lives on the device
- +Thread is far more responsive than Wi-Fi plugs and does not add another device to your router's DHCP table
- +Acts as a Thread router, so each one you add strengthens the mesh for locks and sensors
- +TÜV and UL certified
Cons
- −$39.95 for one plug — five times the per-plug cost of a SwitchBot 4-pack
- −Useless without a Thread border router; a phone alone cannot commission or control it
- −Physically the biggest indoor plug in this comparison at 70 x 39 x 60 mm
- −No motor or HP rating published, so inductive loads are unspecified
- −1-year warranty at a flagship price
