2026 verdict
Shelly Plug PM Gen3 has the better all-around case than TP-Link Kasa EP40 in 2026, starting with warranty, maximum load power, and energy monitoring.
What pushes it ahead is warranty, maximum load power, and energy monitoring, and connectivity keeps the advantage from looking narrow. TP-Link Kasa EP40 remains a niche alternative if rating, weather resistance, and On/Off button matter more than the rest of the comparison. That is enough to make Shelly Plug PM Gen3 the better pick for most buyers.
