Longer Range and Stable Control
Turn a PC, Raspberry Pi, or server into a powerful Zigbee/Thread gateway with the SONOFF Dongle Plus MG24 adapter. Built on the high-performance EFR32MG24, it delivers faster automations, longer range, and rock-solid control of multi-brand devices — ideal for open-source enthusiasts and pro installers alike.
Why You’ll Love It
- MG24 Performance Leap: EFR32MG24 with 1536 KB Flash and 256 KB RAM ensures snappy automations and quick responses from sub-devices.
- Stronger, Wider Coverage: External antenna with 3 dBi gain (up to 4.5 dBi with correct angling/channel) reaches up to 200 m in open space.
- Open-Source Ready: Works seamlessly with Home Assistant, Zigbee2MQTT, openHAB, and others — for local, private automations.
- Flash in Minutes: Easily change roles and firmware using the Dongle Flasher Web Tool or the Add-on.
- Cleaner Signal, Fewer Drops: The included 1 m USB extension cable allows you to place the dongle away from interference for higher stability.
- Built to Last: Compact aluminum alloy body with a modern look (24-hour salt-spray tested).
Flexible Roles with Flashable Firmware
- Zigbee Coordinator (EmberZNet/EZSP): Locally add and manage large fleets of Zigbee 3.0 devices.
- Zigbee Router: Strengthen the mesh, extend coverage, and stabilize distant end devices.
- OpenThread RCP: In conjunction with a Thread Border Router, connect and control Matter (via Thread) devices.
- MultiPAN RCP (Zigbee + Thread 2-in-1): Coordination and monitoring of both networks with a single dongle.
Role switching is fast — upload the desired firmware via the official tools above and you are ready to go.
Designed for Real-World Installations
- Omni-Adjustable Antenna: Angle it towards receiving devices for a more stable connection.
- Electromagnetic Hygiene: The extension cable separates the dongle from USB 3.0 ports and metal enclosures, minimizing 2.4 GHz band interference.
- Core Adapter for Mixed Brands: Unify devices from multiple manufacturers under one local, private platform.
