Smart Plugs / Meross
Meross Matter Smart Plug with Energy Monitor MSS315 (4-Pack)
Matter plus real metering in a four-pack — at a price the Kasa undercuts badly.
Overall score 7.4/10
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
Meross Matter Smart Plug with Energy Monitor MSS315 (4-Pack) review: what the specs say
Matter plus real metering in a four-pack — at a price the Kasa undercuts badly. At $52.99, Meross's 2023 model sits at the premium end of the category — the smart Plugs we compare run from $11.99 to $52.99. It scores 7.4/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Ecosystem Support at 8.5/10 — matter, HomeKit, Alexa, Google, SmartThings and Home Assistant coverage. The weakest is Load Headroom at 5.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: $13.25 a plug at Meross's own store price — 60% more than a Kasa EP25 for the same job plus Matter; and meross explicitly requires a Matter-compatible hub and an IPv6-capable network; a bare phone will not do. Every specification on this page comes from Meross's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
