Idle shutdown timer

Hi, I’m trying to access the idle shutdown timer set under the power saving tab in settings from a addon using

Code:
xbmc.getCondVisibility('System.HasAlarm(shutdowntimer)')

and

Code:
xbmc.getCondVisibility('System.AlarmLessOrEqual(shutdowntimer,300)')

This however does not seem to work. Never triggers the “AlarmLessOrEqual” and always shows there is no alarm no matter how long it’s been idle. I’m wondering if the alarm name is something different or if this setting is using alarms or something else?

Thanks
