This device comes with Tasmota already installed!

Preflashed version is not available from all vendors!

Serial Flash

Download tasmota32-zigbeebridge.factory.bin unofficial precompiled firmware from development branch and flash the ESP32 module. Or use tasmota32-zigbeebridge.bin for OTA upgrade.

Flash Zigbee module

Zigbee module flashing is broken in recent versions of Tasmota! You need older version (e.g. 9.5.0) likely manually compiled (see below) for successful flashing of Zigbee module. Related tasmota issue: #23001

Download Zigbee module firmware (for example: ncp-uart-sw_6.7.8_115200.ota) from Tasmota GitHub located in Tasmota/tools/fw_SonoffZigbeeBridge_ezsp/.

Go to Firmware Upgrade and next to “Upgrade by file upload” use the Choose File button and select Zigbee module firmware you downloaded f.e. (ncp-uart-sw_6.7.8_115200.ota).

ZBBridge Zigbee module flash

Click on Start upgrade, be patient and wait for a few minutes until flashing is complete. Once it is done, Tasmota will reboot. If the flash was successful the console will show Zigbee2Tasmota starting:
