Hello,
I need your support, today I got after HA restart this message

Driver: Failed to open the serial port: Error: No such file or directory, cannot open /dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_ea141d913d85ed11aa41c89f9d1cc348-if00-port0 (ZW0100)

I'm not 100% sure what that means, could it be that the z-wave stick is damaged; I don't see the stick in the system?
Thanks for your help and hints

Thanks, but unfortunately I don't see my Z-Wave stick, is this an hint that the stick is maybe damaged?

is it possible to recover a new stick with the Automatic/Scheduled backups: Scheduled backup of NVM and store directory. It's also possible to enable automatic backups of NVM before every node inclusion/exclusion/replace, this ensures to create a safe restore point before any operation that can cause a network corruption. ?

Are you using docker or what else?

Anyway it is possible to restore sticks backups but IMO the problem here is different, if you are using docker it could be you are not mapping the device correctly inside the container
