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
Emporia Energy Monitoring Smart Plug (1-Pack)
Pros
- +The metering is the product, and it slots straight into Emporia's whole-home energy dashboard
- +$11.99 single or $34.99 for four direct from Emporia — the cheapest per-plug metering in the category
- +Emporia is unusually honest about its limits, publishing a continuous rating and a do-not-use list
Cons
- −10A continuous, not 15A — the 15A figure is a peak good for one hour a day, so the real ceiling is about 1,200W
- −Emporia's own store tells you not to plug in a fridge, freezer, pump, heat lamp or router
- −Roughly 80,000 North America Smart Plugs sold July 2022 to May 2023 were recalled by CPSC in September 2023 for inadequate grounding (electric shock hazard); check what you receive
- −Alexa and Google only — no HomeKit, no Matter, no local control, no Home Assistant path
- −Emporia publishes no dimensions, so you cannot tell in advance whether it blocks the second socket
