SONOFF
Zigbee 3.0 USB Coordinator (EFR32MG21)
Plug this into your Home Assistant box and start pairing Zigbee devices immediately. The EFR32MG21-based dongle works with both Zigbee2MQTT and ZHA out of the box, supporting Zigbee 3.0 and hundreds of devices from IKEA, Aqara, Sonoff, Hue, and more. One dongle coordinates your entire Zigbee network.
Project idea: Set up a whole-house Zigbee network in Home Assistant with Aqara door sensors, IKEA smart plugs, and Sonoff temperature sensors, all coordinated through this single dongle.

Frequently Asked Questions
Should I use Zigbee2MQTT or ZHA with this dongle?
Both work well. Zigbee2MQTT supports more devices, updates faster, and runs as a separate service (good for stability). ZHA is built into Home Assistant with zero extra setup. If you are starting fresh and want maximum device compatibility, Zigbee2MQTT is the stronger choice.
Can I use this dongle with a Raspberry Pi running Home Assistant?
Yes. Plug it into any USB port on your Pi. Home Assistant OS, Supervised, and Container installs all support USB Zigbee coordinators. If using a Pi 4, plug into a USB 2.0 port (the black ones) to avoid potential USB 3.0 radio interference with Zigbee's 2.4 GHz band.
