Data from Amazon and official Meross and Shelly sites.

2026 verdict

Need scripting and energy data, or weatherproof outdoor outlets? The Shelly Smart Plug (US) wins this smart plug comparison, coming in cheaper while adding energy monitoring, overheat/overload protection, and richer connectivity (Wi-Fi plus a Bluetooth gateway) with an open API for custom automation. The Meross Outdoor Smart Plug (3 Sockets) counters with IP44 weather resistance, three independently controllable outlets, and a wider integration list that adds Apple HomeKit and SmartThings. Both are 1800W/15A Type B plugs, but they answer opposite needs, one is a scriptable indoor power monitor, the other a weatherproof triple outlet for the yard. 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 (3 Sockets) if you need weatherproof control of three outdoor devices with HomeKit support.
