Meross Outdoor Smart Plug vs Shelly Smart Plug (US) comparison

Updated July 2026

Data from Amazon and official Meross and Shelly sites.

2026 verdict

The Shelly Smart Plug (US) wins this smart plug comparison by being cheaper and packing the features power users want: real energy monitoring, overheat/overload protection, and richer connectivity with 2.4GHz Wi-Fi plus a Bluetooth gateway, all backed by an open API for scripting. The Meross Outdoor Smart Plug carves out its own niche with IP44 weather resistance for outdoor lights and pumps, two independently controllable outlets, and a wider integration list that adds Apple HomeKit and SmartThings. Both are 1800W/15A Type B plugs, but they answer different needs, one is a scriptable indoor power monitor, the other a weatherproof dual outlet. Choose the Shelly Smart Plug (US) if you want energy tracking, an open API and a lower price for indoor automation; choose the Meross Outdoor Smart Plug if you need weatherproof outdoor control and two outlets with HomeKit support.
