Zigbee 3.0 Signal Repeater USB Signal Amplifier Extender For Tuya EWeLink Home Assistant ZigBee2MQTT Tasmota Device Automation Description: 1、Pre-flashed with EZSP v8 (EmberZNet Serial Protocol version 8) 2、Can use ZHA in Home Assistant or Zigbee2MQTT (pre-alpha) 3、Base on EFR32MG21 CH340E 4、 20dBm output gain，PCB antenna 5、Plastic Shell 6、Support OTA Via Uart (Press the BOOT button,then press and release the nRST button, finally release the BOOT button) 7、Baud rate ：115200 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! 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) Specifications: 1. Pre-flashed with EZSP v8 (EmberZNet Serial Protocol version 8)：The device has been pre-flashed with EZSP v8, which is an EmberZNet Serial Protocol version 8. 2. ZHA in Home Assistant or Zigbee2MQTT (pre-alpha)：It supports ZHA (Zigbee Home Automation) and can be used with Home Assistant or Zigbee2MQTT (pre-alpha). 3. Base on EFR32MG21 CH340E：The device is based on the EFR32MG21 CH340E, which provides excellent performance and compatibility. 4. 20dBm output gain，PCB antenna：The device has an output gain of 20dBm and uses a PCB antenna for better signal quality and range. 5. Plastic Shell：The device is designed with a plastic shell for protection and durability. 6. Support OTA Via Uart (Press the BOOT button,then press and release the nRST button, finally release the BOOT button)：It supports OTA (Over-The-Air) updates via Uart, which allows for easy and secure updates without requiring manual intervention. To perform the update, press and hold the BOOT button, then press and release the nRST button, finally release the BOOT button. Package Included: 1*ZigBee3.0 Universal Gateway USB Dongle
