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.
