I set up a Z-Bee Do with a Raspberry Pi Zero and zigbee2mqtt, sending data to a separate Home Assistant install. It worked great for a few days, until the serial port stopped responding. I rebooted the Pi, and zigbee2mqtt still times out trying to initialize the adapter. As a double-check I installed zigpy-cli and it has the same problem.
What’s tricky is that I don’t have physical access to the device right now, and it’s also powered from the USB port on the same ZigBee board, powering the Pi through GPIO.
Is there anything else I can do? Or, anything I should look for that would explain why it failed in the first place?
