I am monitoring ACPI and other sensors on my mainboard with lm_sensors. there are two entries:
intrusion0: ALARM intrusion1: ALARM
From what I know these are sensors to detect an open case, but there are no headers or pins to connect something like a switch on the mainboard. (AsRock Z86 Pro3 (manuals))
I wonder if I can access these sensors in other ways or if they are just not supported by the board but still active in the chipset. I know how to hide the entries in lm_sensors, that should not be the issue here.
