Zigbee USB dongle Sonoff Dongle Plus MG24 for Zigbee networks — USB adapter, compatible with Home Assistant, openHAB, Zigbee2MQTT

SONOFF Dongle Plus MG24 is a Zigbee USB adapter designed to connect and manage Zigbee and Thread devices with open-source home automation platforms. The compact USB gateway lets you integrate sensors, lights and switches into systems such as Home Assistant, Zigbee2MQTT, openHAB or ioBroker, providing a local coordinator for Zigbee networks and flexible integration options.

Advantages

A detachable antenna with up to 4.5 dBi gain and a supplied 1 m USB extension cable increase effective range and allow convenient placement. The aluminum casing and endurance testing (including temperature, corrosion and over 500 USB plug/unplug cycles) ensure a durable and reliable product. Multiple operation modes — ZigBee coordinator, ZigBee router, Thread RCP or MultiPAN — and an easy firmware upload process via SONOFF Dongle Flasher facilitate flexible use and quick updates.
