Close to pulling my hair out - unable to configure Zigbee2MQTT

Configuration Zigbee

I have tried just about everything and it just will not work. This is the error log :

I am using the ZBT-1 and here is my configuration

socat:

slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
options: "-d -d"

If someone can assist, I will be forever grateful

Try deleting the coordinator_backup.json file

Thanks - I have tried that with zero success.

I don’t know if SkyConnect is compatible with ember.
Have you tried

  adapter: ezsp

Did you update the firmware to support ember? Otherwise try ezsp driver.

And you don’t have ZHA enabled on the same dongle? Only one Coordinator software can run at the same time on one USB coordinator.

So if you also have ZHA, you need to disable/remove ZHA first.
