## Summary description

Sonoff Dongle PLUS MG24 is a USB network adapter for smart home systems that supports Zigbee and Thread protocols and provides MQTT integration. Designed to connect and manage compatible smart devices through a local hub or home automation controller, it enables device discovery, communication bridging and reliable low-latency control for automation and monitoring tasks.

## Long description

SONOFF Dongle Plus MG24 (USB Dongle) is a compact Zigbee and Thread adapter built on the EFR32MG24 chipset (1536 kB Flash, 256 kB RAM). The device supports operation as a Zigbee coordinator, Zigbee router or OpenThread RCP (MultiPAN) and is compatible with third-party platforms such as Home Assistant, Zigbee2MQTT and openHAB. An external antenna (approx. 3 dBi, upgradable to ~4.5 dBi) and supplied 1 m USB extension cable help extend range and allow flexible placement to reduce interference. The aluminum-alloy enclosure is designed for professional installations and the dongle provides up to ~200 m line-of-sight range under ideal conditions.
Advantages
The Dongle Plus MG24 combines dual-protocol support (Zigbee and Thread) in a single USB device, offering flexible roles (coordinator, router, OpenThread RCP) and broad platform compatibility. High-performance EFR32MG24 hardware ensures reliable local automation processing and stable sub-device control. External antenna and included USB extension cable enable improved radio performance and flexible positioning. The aluminum enclosure provides durable, professional-grade housing suitable for longer-term installations.
