Compact USB Dongle
Overview
The SONOFF Dongle-LMG21 (Dongle Lite MG21) is a compact USB Zigbee 3.0 coordinator that lets you create fast, reliable local control with Home Assistant, Zigbee2MQTT, openHAB, and other platforms. Built on the EFR32MG21 radio, the hardware provides a stable Zigbee mesh network, allowing bulbs, switches, and sensors from different brands to be paired and controlled within a single system.
The dongle works in a Plug&Play manner on Windows, Ubuntu, and Raspberry Pi OS (including Docker environments), and its external, ≤180° adjustable antenna delivers better range. For advanced users, flashable firmware is available (Zigbee NCP/Router, OpenThread RCP, MultiPAN), enabling configuration for multiple network roles as needed.
