Shelly Pro 1 Smart DIN Rail Switch

The Shelly Pro 1 sets an advanced industry standard for single-circuit switching and versatile device automation inside electrical enclosures. Engineered specifically for seamless physical integration on standard DIN rails, its standout feature is the native LAN (Ethernet) port. This wired architecture ensures stable network uptime and completely immunizes the module against local radio interference, making it an essential component for high-end automated residences, commercial spaces, and industrial environments.

The true operational versatility of the Shelly Pro 1 comes from its output channel equipped with a potential-free dry contact. This mechanical design empowers system integrators to power the module at 230V while switching a completely separate electrical line running at a different voltage or phase. For instance, you can easily control a 12V/24V low-voltage gate opener, a door strike, or an external power contactor, making it an excellent driver for access control systems, motorized valves, and independent lighting zones.

Housed inside a durable, flame-retardant shell, the module continuously screens internal thermal metrics to immediately trip connected lines within milliseconds if dangerous temperatures are detected. Out of the box, the Shelly Pro 1 implements full support for local JavaScript scripting and MQTT protocols, ensuring reliable, low-latency interoperability with Home Assistant, Amazon Alexa, and Google Home setups.
