Hey everyone, I wanted to share my recent experience with my Zigbee setup. I’ve been using Zigbee2MQTT for years and it’s been mostly trouble-free. However, this morning, all my Zigbee devices suddenly became unavailable while my MQTT devices were still working fine. I was a bit puzzled but decided to dive into troubleshooting.First, I checked my configuration. I’m using the Sonoff Dongle P as my coordinator and my Zigbee2MQTT setup seemed solid. The error logs pointed to a USB adapter discovery issue, specifically mentioning that no valid USB adapter was found. This was confusing because my adapter had been working perfectly until now.I decided to check the USB port and restarted my system to ensure everything was recognized properly. After a few reboots, the issue persisted. I then looked into the logs more carefully and noticed a mention of a watchdog failure. This led me to consider the possibility of a firmware update or a corrupted configuration.I tried disabling the watchdog and restarting the service, but the problem remained. Finally, I decided to completely reinstall Zigbee2MQTT, ensuring all dependencies were up to date. After reinstalling, I carefully followed the setup guide again, making sure the USB adapter was correctly identified.To my relief, everything started working again! All my Zigbee devices are back online, and my setup is as stable as it was before. This experience taught me the importance of thorough troubleshooting and the value of community resources like the official Zigbee2MQTT documentation.If anyone else runs into similar issues, I’d recommend checking the USB connections, reviewing the logs for specific errors, and considering a clean reinstall as a last resort. It’s also a good reminder to regularly back up configurations and keep an eye out for firmware updates.Overall, it was a bit stressful, but resolving the issue gave me a sense of accomplishment and a deeper understanding of my system. Thanks to the supportive community and the wealth of resources available, I was able to get everything back up and running smoothly!
