Dongle USB Zigbee/Thread Sonoff Dongle Max (MPN Dongle-M) pour Home Assistant et Zigbee2MQTT

SONOFF Dongle Max is a USB Zigbee and Thread radio gateway (model Dongle-M) designed to integrate Zigbee and Thread devices with Home Assistant and Zigbee2MQTT. It works as a Zigbee coordinator and supports Thread RCP, providing a stable connection for sensors, switches and smart lights. The dongle can connect via Ethernet with PoE, Wi‑Fi or USB-C, allowing flexible placement in home or office installations.

Advantages

The device combines two proven chipsets — EFR32MG24 for Zigbee/Thread and ESP32 for Wi‑Fi — to ensure reliable performance, efficient power use and fast data transfer. Multiple connection options (PoE Ethernet, Wi‑Fi or USB‑C) and a local web console simplify setup and management without additional software. The gateway supports acting as coordinator, router or Thread RCP and offers remote firmware switching, webhook notifications and control of LED indicators.
