Overview

The Sonoff Dongle Plus MG24 (Dongle-PMG24) is a high-performance Zigbee 3.0 and Thread USB adapter designed for smart home enthusiasts and power users. Powered by the advanced EFR32MG24 chip with 1.5MB Flash and 256KB RAM, it offers exceptional stability and processing speed for managing large-scale smart device networks locally.

Housed in a durable aluminum alloy casing, the dongle features an external 3dBi antenna that provides a stable signal range of up to 200 meters in open spaces. It is a versatile tool that can be flashed with different firmware to act as a Zigbee coordinator, a router, or an OpenThread RCP for Matter-over-Thread compatibility, ensuring your smart home is future-proof.

Seamlessly integrating with open-source platforms like Home Assistant (via ZHA or Zigbee2MQTT), openHAB, and ioBroker, this dongle allows you to build a private, local smart home ecosystem without relying on cloud services. The included 1-meter USB extension cable ensures optimal placement to minimize electromagnetic interference from nearby electronics.

  • openHAB
  • ioBroker
  • Zigbee 3.0 / IEEE 802.15.4 devices

  • No cloud required — works entirely locally
