Shelly PRO 3

Easily and affordably automate your electrical panel or power circuits with this smart Shelly PRO 3 WiFi and LAN DIN-Rail switch. Control or automate up to 3 circuits with your smartphone from anywhere in the world, or set up convenient schedules and scenes via the free Shelly App. No expensive Gateway or Hub required! The potential-free relays also allow you to switch DC and 3-phase power.

For example, if you connect your lighting and appliances to one circuit, you can turn them on/off with a single press of a button, making it handy for the office. Never forget to turn off the lights again, prevent standby power leakage, and save on energy costs. The potential-free relays (dry contact) allow you to switch any voltage you want. Voice control with Google Assistant or Amazon Alexa is also possible.

This smart WiFi and LAN DIN-Rail switch can be installed in your electrical panel and switches 3 circuits of up to 16A (3680W) each, with a total maximum of 48A. Install the Shelly PRO 3 and connect via Bluetooth for easy pairing with the App. Click on "Add Device" in the menu and follow the instructions. After that, you can wirelessly control the switch with the App from anywhere in the world, integrate it into smart scenes (scenarios), and set timers.

The Shelly PRO 3 is equipped with the new ESP32 processor with 8MB flash, supports mjS scripting, and also has a local HTTP server (port 80), which functions as a simple web page where the user can set basic parameters. This allows you to control the Shelly PRO 3 via web requests and integrate it with your home automation or smart home system.

Also works with

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

If you prefer not to use the free Shelly cloud service but still want to control your devices remotely, no problem. The Shelly PRO 3 also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central broker. The devices involved only communicate with the broker and do not know each other. They don’t need to know the IP addresses or technical details of other participants. This ensures safe and reliable communication, with real-time monitoring and easy integration. Want to know more? Read our Shelly WiFi Switch Blog.
