Zigbee2MQTT wont find Coordinator

Configuration Zigbee
1

Hi everyone,

I currently have a somewhat strange problem. I have the following Zigbee Coordinator in use: Zigbee CC2652P2 TCP Ethernet Coordinator | 90810
This runs with Zigbee2MQTT on Home Assistant as an add-on. Everything has been running stably and without problems for about a year. Then on Monday we had a power failure. However, I backed up everything in this area with a UPS. So things continued to run. When the power outage lasted a little longer, I shut down the servers with Home Assistant. The Zigbee Coordinator continued to run via PoE. I must have shut down Home Assistant dozens of times and never had a problem. Now I get the following message:

I have already looked here: Zigbee2MQTT fails to start | Zigbee2MQTT However, none of this applies. The IP address and port have not changed, nor has the config. I have already restarted Coordinator several times, but that doesn’t help either. And until Sunday everything worked fine.

Does anyone have any tips on where else I could look? Half of my Smart Home is now down… :frowning:

Thank you very much

Before below make sure things are running normally, you are not in safe mode or have some other integration crashing and spamming the logs.

Personally I would power down the stick, reboot (not restart) the ha host and I’m making the assumption that would restart the addon as well, then just at the beginning of the host reboot, power up the stick. Give it 5 minutes to give it a chance to go. Watch the addon log.

If that not work, I would make certain I copied the addon config and blow the addon container away, rebuild it, install the same config.

Move 3, not sure.

Thank you very much. I could have thought of that myself. I have now proceeded as follows:

  1. disconnected the coordinator from the power supply for several minutes
  2. shut down the Home Assistant VM
  3. updated the Coordinator with the latest firmware to be on the safe side
  4. started the coordinator
  5. started Home Assistant

It took a while for everything to recover, but now everything is working again.

Thanks again

Joe
