Shelly PRO 2

Automate your circuit breaker or power circuits easily and affordably with this smart Shelly PRO 2 WiFi and LAN DIN-Rail switch. Control or automate up to 2 groups with your smartphone from anywhere in the world, or set up handy switching schemes and scenes via the free Shelly App. No expensive Gateway or Hub required! This is the new version (no DC connection).

For example, if you connect your lighting and devices to one group, you can turn them on or off with a single button press—convenient for office use. Never forget to turn off the lights again, prevent standby power leakage, and save on energy costs. Through the potential-free relay (dry contact), you can switch any voltage you like. Voice control with Google Assistant or Amazon Alexa is also possible.

This smart WiFi and LAN DIN-Rail switch can be installed in your circuit breaker box and switches 2 groups of up to 16A (3680W) each, with a total maximum of 25A. Install the Shelly PRO 2 and connect via Bluetooth for easy pairing with the App. Click on Add Device in the menu and follow the instructions. Afterwards, you can control the switch wirelessly with the App from anywhere in the world, integrate it into smart scenes, and set up timers.

The Shelly PRO 2 features the new ESP32 processor, supports mjS scripting, and also includes a local HTTP server (port 80), which acts as a simple web page where users can set basic parameters. This allows you to control the Shelly PRO 2 via web requests and integrate it with your home automation or smart home system.

Works with:

_{* FIBARO Home Center 2, 3, or Lite via a Virtual Device/Quick App
** Apple HomeKit requires flashing or a Homebridge}

Would you prefer not to use the free Shelly cloud service but still control your devices remotely? No problem. Shelly PRO 2 also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central mediator: the MQTT broker. The involved devices only communicate with the broker and do not know each other directly. They do not need to know the IP addresses or technical details of other participants. This ensures safe and reliable real-time monitoring and easy integration. Want to know more? Read our Shelly WiFi Switch Blog.
