All credits to thehelpfulidiot (with the fantastic blog article) and the original Tasmota firmware, many thanks!
The build is based on Tasmota v12.0.2 and support hot/cold reboot. Successfully tested on eWeLink gateway - ZB-GW03-V1.3
You can find the product in many places, including Amazon (already purchased this one).
ZB-GW03 Zigbee to LAN bridge/gateway based on Espressif ESP32 and a Silicon Labs EFR32MG21 Zigbee radio (CoolKit-Technologies "SM-011 V1.0" module).
- ZB-GW03 eWeLink Ethernet Zigbee Gateway (ZB-GW03-V1.0, ZB-GW03-V1.2, ZB-GW03-V1.3), also sold rebranded as:
- Eachen eWeLink ZigBee Smart Hub
- SmartWise Zigbee Bridge Pro
Install the platformio in CLI with:
pip3 install -U platformio
platformio run -e tasmota32-EWELINK
Firmware will be located at .pio/build/tasmota32-EWELINK/firmware.bin
You can use the already built firmware in this git repository bin/tasmota32-EWELINK_11.1.0.bin located here.
Use any tasmota flasher with the previous bin file. Take a look to the official documentation.
Firstly, set up your Tasmota with the WiFi access point: connect it and open 192.168.4.1 to enter your WiFi credentials.
Secondly, add this template in the console (ETH support):
backlog Template {"NAME":"ZB-GW03-V1.3","GPIO":[0,0,3552,0,3584,0,0,0,5793,5792,320,544,5536,0,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,608,640,32,0,0,0,0,0],"FLAG":0,"BASE":1} ; module 0
Then, perform a firmware upgrade with the bin/ncp-uart-sw-6.7.9_115200.ota located here (original source).
Now, plug the ethernet and check in Information that you have a valid ethernet IP address.
For better stability, desactivate permanently the WiFi with:
Wifi 0
backlog rule2 on system#boot do Wifi 0 endon ; rule2 1
Remap Zigbee Tx/Rx pin to the TCP interface with:
backlog template {"NAME":"ZHA-bridge","GPIO":[0,0,5472,0,5504,0,0,0,5793,5792,320,544,5536,0,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,608,640,32,0,0,0,0,0],"FLAG":0,"BASE":1} ; module 0
And finally start the TCP server:
backlog rule1 on system#boot do TCPStart 8888 endon ; rule1 1 ; tcpstart 8888
Congrats, your eWeLink Zigbee gateway has been converted to an opensource ZHA bridge!
With Home Assistant, add the Zigbee Home Automation integration with the ethrnet IP adress and port number 8888.
