Shelly 1PM Gen 3 Smart Wi-Fi Switch

The Shelly 1PM Gen 3 delivers premium, industrial-grade smart energy management and high-power circuit switching. The core advancement of this third-generation device is its upgraded internal architecture, featuring the proprietary Shelly Chip equipped with 8MB of flash memory. This expanded hardware specification doubles the module's processing capabilities, securing robust Wi-Fi connectivity, smoother local script executions, and immediate responsiveness without depending on a continuous internet connection.

Capable of shifting active electrical loads up to 16A, the Shelly 1PM Gen 3 is a versatile asset for automating standard wall outlets, heavy architectural lighting systems, or power-hungry appliances (such as water heaters, HVAC equipment, and pump motors). The real-time power analytics enable installers to design automated cost-saving loops—like cutting power to non-essential lines during peak utility tariff hours—and provide critical diagnostic telemetry to detect anomalous spikes that indicate an appliance is nearing failure.

Engineered with multi-layered safety barriers for professional integration, the device continuously monitors internal temperature, current load, and voltage levels, automatically isolating the electrical circuit within milliseconds if a threshold is crossed. Completely compatible with Home Assistant, Amazon Alexa, Google Home, and MQTT, the Shelly 1PM Gen 3 is the perfect building block for reliable and scalable energy management grids.
