Identify and remove failing devices

[tschreier]

Hi everybody,

after a DB crash I had to restore my DB from a old Backup unfortunately in the meantime some devices already have been replaced and others had been removed.
Today I would like to clean my devices and remove all the failing devices, is there a way to identify "Not Working Devices" unfortunately the "not used" is just show the devices which haven't been added.

Have somebody a good suggestion to share ?
Thank you for your Help.
Best regards
Thomas
