I’m running HA Yellow and all my Zigbee devices are not responding after some updates. I tried to restore to the previous backups, but none of them seem to work. I think there was firmware update on the zigbee dongle. I followed manual update instructions (Flash Silicon Labs radio firmware manually · NabuCasa/silabs-firmware Wiki · GitHub), and I tried some of the firmwares but they all gave me the error message.
Any ideas and suggestions are gratefully appreciated. Thanks!
