Shelly Plus 1PM Smart Wi-Fi Switch

The Shelly Plus 1PM stands as a proven benchmark for smart energy tracking and high-capacity electrical circuit switching in professional smart building layouts. Built upon the reliable Plus Series framework (Generation 2), it leverages the advanced ESP32 microcontroller. This internal upgrade ensures lightning-fast command responsiveness, reinforced local security protocols, and the ability to process automation scripts completely onboard, drastically minimizing reliance on internet stability or external cloud servers.

Engineered to shift active electrical currents up to 16A, the Shelly Plus 1PM is an ideal choice for automating main wall sockets, critical high-wattage lighting lines, or heavy household appliances (such as electric water heaters, space heaters, and laundry systems). Its individual power monitoring engine records real-time electricity metrics, providing critical telemetry data to establish custom load-shedding routines or monitor appliance health by catching abnormal standby draws. A key structural benefit for custom installers is its compatibility with the Shelly Plus Add-on, enabling the direct wiring of physical temperature, humidity, or reed sensors to the module without creating a complex hardware web.

Housed in a compact shell designed to fit easily behind standard wall boxes, the module features multi-layered embedded safeguards that instantly isolate the line during voltage spikes, current surges, or high internal heat. Completely compatible with Home Assistant, Amazon Alexa, Google Home, and MQTT, the Shelly Plus 1PM is a trustworthy, scalable, and versatile asset for modern automation networks.
