Shelly Pro 2 Smart DIN Rail Switch

The Shelly Pro 2 sets an advanced industry standard for dual-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 2 comes from its 2 fully independent channels equipped with potential-free dry contacts. This mechanical design empowers system integrators to switch completely separate electrical lines running at different voltages or even different phases within a single hardware block. For instance, you can control a 230V lighting grid on one channel and a 12V/24V low-voltage gate opener or door strike on the other, making it an excellent driver for access control, 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 2 implements full support for local JavaScript scripting and MQTT protocols, ensuring reliable, low-latency interoperability with Home Assistant, Amazon Alexa, and Google Home setups.
