Flashing instructions for tasmota32 firmware.

Requires an ESP32 binary with Ethernet support. Download unofficial `tasmota32-ethernet.bin`development build.

Serial Flash

Download tasmota32-zigbeebridge.bin unofficial precompiled firmware from development branch and flash the ESP32 module.

Flash Zigbee module

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).

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:
