⚠️ A Zigbee hub is mandatory to access remote data, alerts, and automations. The LCD screen works autonomously without a hub, but all connected functions require a compatible Zigbee gateway.

Compatibility Table

💡 For beginners: without a Zigbee hub, the LCD screen remains functional and displays data locally. To benefit from alerts, history, and automations, we recommend the SONOFF ZBDongle-E with Home Assistant, or the SONOFF NSPanel Pro for an all-in-one wall-mounted screen solution.
