Our company has a mobile checkin solution that comes in a suitcase and on all of them I have teamviewer installed (remote access enabled) so we can assist when needed.
I can see when a device is online, but I can not see when an offline device was online for the last time.
I think that would be a handy feature which can easaly be unlocked because you already store this information (how else can you show that a device has been offline for more then a year)
