My Zigbee network failed a few days ago. Devices were unresponsive, the log was full of errors, and nothing worked.
After 2 years I wanted to throw #homeassistant through the window.
I downgraded z2m. Fixed wifi/Zigbee channels to reduce interference. Disconnected rogue devices. Researched all the forums. Nothing worked.
Today, as a last attempt, I updated the firmware on my Sonoff dongle.
Suddenly everything works again, snappier, even OTA!
Happy.
