Pros & Cons
Wyze Plug Outdoor (WLPPO1-1)
Pros
- +One of very few outdoor plugs that actually meters power — the Kasa EP40M does not
- +1/2 HP motor rating and a -4°F floor make it usable for pumps and winter lighting
- +Two separately scheduled outlets for $14.99 each
- +Amazon regularly discounts it well below Wyze's own $29.98 list
Cons
- −Everything runs through Wyze's cloud; there is no local API and no Home Assistant support without reflashing
- −No Matter, no HomeKit, no SmartThings — Alexa, Google and the Wyze app only
- −15A is the combined budget for both outlets, not each
- −IP64 is splash protection; the sockets must face down and the rating says nothing about a cord in the socket
- −1-year warranty unless you buy direct from Wyze for 18 months
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
