The Sonoff Dongle‑PMG24 - fully named "Zigbee/Thread USB DonglePlus MG24" - is one of Sonoff's most complex USB dongle solutions, offering unparalleled performance and versatility. The built-in high-performance EFR32MG24 chip (SoC) has a capacity of 1536KB Flash and 256KB RAM, thus providing much more resources than previous models. This allows for faster automation response time and more stable sub-tool handling.

The device is equipped with Zigbee coordinator firmware from the factory, but with the SONOFF Dongle Flasher web tool, it can be easily flashed to other roles - for example, Zigbee router, OpenThread RCP or even MultiPAN device - all in just 1 minute. The package also includes a 1m long USB extension cable, which enables convenient placement and minimizes interference.

The device's aluminum alloy housing is durable, corrosion- and pressure-resistant, and offers a modern tech appearance. The built-in antenna works with 3dBi amplification, with optimal settings up to 4.5dBi, which means that a range of up to 200 meters can be achieved in open space. The device is an excellent choice for both advanced DIY smart home developers and advanced users looking for a reliable, high-performance multi-protocol controller.
