Shelly Pro 1PM Smart DIN Rail Switch

The Shelly Pro 1PM sets a professional industry benchmark for heavy-duty circuit switching and advanced smart energy management inside electrical enclosures. Engineered specifically for seamless physical integration on standard DIN rails, its standout feature is the native LAN (Ethernet) port. This wired connection ensures stable network uptime and completely immunizes the module against local radio interference, making it an essential component for high-end automated residences, commercial grids, and manufacturing spaces.

Capable of shifting active electrical loads up to 16A, the Shelly Pro 1PM is an ideal choice for automating main wall outlets, heavy lighting lines, or power-hungry appliances (such as electric water heaters, space heaters, and HVAC equipment). Its precise individual power monitoring engine ("PM") tracks real-time electricity metrics, providing system integrators with the technical depth needed to establish automated cost-saving loops, monitor appliance efficiency, and catch abnormal draws.

Housed inside a durable, flame-retardant shell, the module continuously screens internal telemetry to immediately trip connected lines within milliseconds if a threshold is crossed. Out of the box, the Shelly Pro 1PM supports custom JavaScript micro-scripting alongside native MQTT protocols and local Webhooks, providing flawless, low-latency interoperability with Home Assistant, Amazon Alexa, and Google Home setups.
