Hi, I am new to home assistant. I have just purchased Home Assistant Green and a ZBT-2. I installed MQTT Broker and Zigbee2MQTT but Zigbee2MQTT is not starting. When I configure Zigbee2MQTT under found devices my ZBT-2 is found and I have double checked it has the zigbee firmware installed on it. I really dont know how to get this working. Log is below. Thank You.
Starting Zigbee2MQTT without watchdog.
