Sonoff ZBBridge and Home Assistant Integration with TASMOTA

NOTE: I have not tested this as yet. Waitong on eqipment to arrive.

Flash TASMOTA

Flash TASMOTA firmware as with any standard Sonoff device. Use the latest zbbridge firmware

Once flashing has been completed make sure to continue with all cables disconnected and only power from the USB-C cable.

Flash Zigbee Chip

The Sonoff ZBBridge has two chips. One for the ESP8266 chip where we flashed TASMOTA to. The other chip is for the Zigbee operation. You use the same upload button. I'm guessing TASMOTA knows the firmware we are upload is for the Zigbee chips as you can't specify which chip to upload to. I'm guessing the TASMOTA firmware upload tool looks at the header of the files and knows where to send the firmware.

Upload the latest Zigbee firmware. The latest version as of writing is ncp-uart-sw_6.7.8_115200.ota

Configuration

Open two browsers and access the console on each. One for monitoring status and the other for issuing commands.
