Pros & Cons
Kasa Matter Smart Outdoor Plug EP40M
Pros
- +1/2 HP motor rating — three times the EP25's, which matters for pond pumps and inflatables
- +Two outlets you can schedule separately, so lights and a pump are not tied together
- +Matter multi-admin plus a wide -4°F to 122°F operating range for real winter use
- +2-year warranty, unusual for outdoor gear at this price
Cons
- −No energy monitoring at all, and TP-Link has publicly refused to add it — the cheaper indoor Kasa plugs meter, this does not
- −IP64 is splash resistance, not immersion; a plug sitting in standing water or snowdrift is outside the rating
- −15A is the total for the pair, not per outlet — two 1,000W devices will trip it
- −Needs a Matter controller for Apple, Google or SmartThings; only the Kasa app works standalone
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
