For no reason Controller thinks that all devices are failed - the last ok status is equal to the start of service. I tried to restart the system but it does not help

I cannot control any device. How to fix it?
In expert inteface there is a lot of failed jobs with message:

Have you taken backups ?
Take some now !
Both types. Backup & Restore and Expert UI Backup.
Do a power cycle. not just a restart !
Good Luck.

Adding on to the suggestions by @micky1500...

If shutting down and then power-cycling your Pi doesn't fix the problem, the contents of the z-way-server log file (by default, file /var/log/z-way-server.log) should show the cause of the problem.

When I encountered a similar issue, it was caused by a process trying to use the same serial port (/dev/ttyAMA0) that the controller card uses. The following command will show if there are any processes conflicting with Z-Way's use of the serial port: sudo lsof -n | grep AMA0

If the command returns a process that's not a z-way-server process, you have a configuration error on your Pi (most likely in /boot/cmdline.txt or /boot/config.txt due to a conflict related to the console or bluetooth).

Another possibility is a corrupt Z-Way configuration. Hopefully, you've downloaded backups (files ending in .zbk and .zab).
