[Fixed] Conbee III failed to load after power failure

Configuration Zigbee
1

I had my electrical panel replaced today. After power was back up my zigged would not come back up after multiple cold and warm reboots (rPi5 and powered USB hub). This has happened before and a cold boot did the trick but this time it didn’t.

I write this to hopefully leave a breadcrumb for a future trouble-shooter.

After searching this forum and not finding a concrete solution I decided to go into Integrations > Zigbee and on the controller entry I used the sprocket/configuration icon to “change device configuration”. It asked me if it was a new controller or change existing controller. I chose “change controller configuration”. It asked me what USB (tty) to change. The name was apparently different than what it was previously and that was likely the source of the error.

It made a backup of existing network and then progressed to “set up new controller” and offered to use easy install vs custom - I chose easy.

BAM, Bob’s your uncle and I was back up in no time. I hope this doesn’t happen to you but if it does I hope this helps you.

The TTY ports can sometimes change internally, so it is suggested to use the /serial/by-id/ URL that always talks to your dongle by serial number so it is always right.
You can find out what that is by using:

and looking for it under all hardware, something like this:

Once you have the long URL use that instead of the ttyxxx one.
