Sonoff Dongle Plus MG24 USB adapter (Dongle-PMG24) (ZigBee 3.0)

Sonoff Dongle-PMG24 - officially designated »Zigbee/Thread USB Dongle Plus MG24« - is one of Sonoff's most advanced USB-dongle solutions, offering outstanding performance and versatility. Powered by a high-performance SoC EFR32MG24 s 1536 KB Flash and 256 KB RAM, which means significantly more system resources compared to previous models. This allows for faster automation response and more stable management of sub-devices.

The device is factory loaded with firmware for Zigbee coordinator, but can be very easily reprogrammed to other roles using the online tool SONOFF Dongle Flasher - for example in Zigbee router, OpenThread RCP or even MultiPAN device - all in less than one minute. The package comes with 1 metre USB extension cable, which allows flexible positioning and minimises disruption.

Housing made of aluminium alloys is durable, corrosion- and pressure-resistant and gives the appliance a modern and stylish look. Built-in 3 dBi antenna is optimised to 4,5 dBi, which allows you to reach 200 metres in the open. This dongle is a great choice for advanced DIY smart home developers and demanding users looking for a reliable, high-performance multi-protocol controller.
