The Shelly 1PM Gen3 is a powerful Wi-Fi smart relay with built-in power metering, designed for remote control of lights, heaters, boilers, pumps, and other high-load appliances up to 16A. Despite its compact form (37×42×16 mm), it fits neatly behind most wall switches and sockets, making it one of the simplest ways to upgrade any appliance to smart control without replacing your existing installation.
The built-in energy meter gives you precise, real-time visibility into how much electricity each connected appliance consumes. Free cloud storage of energy data lets you analyse usage patterns over time, identify energy-hungry devices, and make informed decisions to lower your electricity bill. Automatic protections against overpower, overcurrent, overvoltage, and overtemperature keep your appliances and home safe at all times.
The Shelly 1PM Gen3 works completely standalone over Wi-Fi — no hub or gateway required. It also supports DC voltage (24–30V), making it suitable for low-voltage applications such as gate controllers, irrigation systems, and HVAC valves. With Matter certification (available via firmware update), it is future-ready for any Matter-compatible smart home ecosystem. Advanced users benefit from full scripting support, MQTT, webhooks, WebSocket, and HTTPS — the full toolkit for complex automations.
An ideal fit for homeowners, rental property managers, and installers looking for a reliable, high-capacity smart relay that integrates with virtually any existing smart home system.
