The D-Bus properties are updated every time SMART data is collected.
This happens at udisksd startup (e.g. at boot-up) and then every ten
minutes (unless the drive is asleep) or when the SmartUpdate() method
is invoked. Applications should only call SmartUpdate() in response to
a user action (never periodically as it may wake up a disk that is
asleep), e.g. for a "Refresh" button or similar in a SMART dialog.
This is what GNOME Disks is doing, see

Hope this helps.
