Inventory and short checks are not easy to do as all devices are only having the S/N indicator as a sticker on the backside.

It would be much easier for onsite services to get the S/N of a device without grabbing it from the wall. There should be an option to display the S/N on the device screen as e.g. most of the Android devices are doing in system info.

The device health page should show the S/N beside the Mac Address. This would help to have an easy S/N to room mapping possible.
