How to use

Install the Shelly 1 PM Gen4 inside a flush-mounted box behind a socket or switch in accordance with local electrical regulations. Ensure the neutral conductor is present and connected. Wire supply and load following the manufacturer’s wiring diagram, secure terminals with the recommended torque and prepare conductors to the specified length. Configure the device using the Shelly app, the local web interface or via Bluetooth, or pair it with a Zigbee or Matter-compatible hub. Use the app or web interface to monitor real-time power readings, set up schedules (up to 20 tasks), create scenes and configure MQTT or Webhooks for automation.

Recommendations

Use an external overcurrent circuit breaker compliant with EN60898‑1 (characteristic B or C, rated current up to 16 A), keep the device within the specified environmental limits and ensure adequate ventilation to avoid overheating. Verify firmware updates and integration settings in your smart home platform for reliable operation.
