Zigbee 3.0 USB Dongle Based on Silicon Labs EFR32MG21 Universal Zigbee Gateway
ZB-GW04 USB Dongle Support via ZHA Zigbee2MQTT Connect Zigbee Device

Notice:
This ZigBee 3.0 usb dongle already with ZigBee2MQTT software pre flashed.

Feature:

It comes pre-flashed with an unsigned EmberZNet 6.7.9 Zigbee NCP application
firmware with Silabs standard EZSP v8 (EmberZNet Serial Protocol version 8)
interface enabled as well as the standard Silabs Gecko Bootloader firmware
for recovery, meaning it can be used either as-is out-of-the-box or flashed
with custom application firmware via USB.

Hardware is at its core based onSilicon Labs EFR32MG21 Series 2 Multiprotocol
Wireless SoC(part numberEFR32MG21A020F768IM32) and aWCH CH340E USB to Serial/UART
Bridge Controller. While it only has a PCB circuit board antenna the radio has
an integrated +20 dBm Power Amplifier (output power) and -104.5 dBm Receive
Sensitivity which should be made for a very good Zigbee coordinator or Zigbee
router if both hardware and firmware were properly implemented.

TheElelabs EZSP Firmware Upgrade Utility(https://github.com/Elelabs/elelabs-zigbee-ezsp-utility/)
orwalthowd firmware update Docker image(https://github.com/walthowd/husbzb-firmware)
can be used to flash the firmware to a newer or older version. New and old firmware
official images are currently being provided at github
(https://github.com/xsp1989/zigbeeFirmware/tree/master/firmware/Zigbee3.0_Dongle)

If the device is following Zigbee standards it is possible it will work with
other gateway solutions, it is just not confirmed as working yet!
