Shelly Pro 2

The Shelly Pro 2 is a two-phase, 2-channel relay supporting 16A per channel and up to 25A combined, for professional lights and appliance automation for residential or commercial use, with Ethernet LAN, WiFi, Bluetooth and MQTT support.

It is equipped with potential-free outputs (dry contacts) offering high flexibility in voltage support and applications. Shelly Pro 2 has scripting functionalities for custom automation scenes based on external data or various occurrences.

Different types of actions, scenarios, and schedules can be set to sync your environment to your daily activities or business needs, via the Shelly smart home ecosystem, including the Shelly Smart Control app – or link it with a popular home automation software such as Home Assistant via a Raspberry Pi!

Enhanced with temperature, overpower, and overvoltage load protection, the Shelly Pro series is designed to be installed inside the breaker box (DIN). Allowing full smart automation with no additional cables or wiring, the Shelly Pro line is perfect for homes, offices, stores, businesses, and manufacturing facilities, as well as new buildings.
