SONOFF Zigbee/Thread USB Dongle | Dongle Plus MG24
Your smart home’s new powerhouse, this USB dongle not only bridges Zigbee and Thread but packs extra performance, flexibility, and reach into one compact stick. High-Performance Core: Powered by the Silabs EFR32MG24 chip (256 KB RAM, 1536 KB flash)—3× more memory and 2× flash than the earlier MG21, making it future-ready for demanding multi-protocol automation. Dual-Protocol Magic: Supports Zigbee and Thread simultaneously, enabling Matter and local open-source automation platforms from a single device. Extended Signal Range: Includes a rotatable 3 dBi SMA antenna (upgradeable to 4.5 dBi), delivering up to ~200 m line-of-sight coverage, great for dense homes or long-range needs. Multi-Role Firmware: Out of the box, it’s a Zigbee Coordinator, but you can flash it to act as a Zigbee Router, OpenThread RCP, or MultiPAN Radio with the easy-to-use Dongle Flasher tool. Interference-Free Placement: Comes with a 1 m USB extension cable to help you position the dongle away from USB 3.0 noise, i
