Mick, hold that thought.
1.006824 Path: UPS.PowerSummary.DelayBeforeShutdown, Type: Feature,
ReportID: 0x0f, Offset: 0, Size: 24, Value: 60

ReportID: 0x11, Offset: 0, Size: 24, Value: 0
Arnaud, is HU_FLAG_ABSENT the right flag here? That seems to indicate that the
variable is not actually implemented on the UPS:
drivers/idowell-hid.c:99:
{ "ups.delay.start", ST_FLAG_RW | ST_FLAG_STRING, 10,
"UPS.PowerSummary.DelayBeforeStartup", NULL, DEFAULT_ONDELAY, HU_FLAG_ABSENT,
NULL},
{ "ups.delay.shutdown", ST_FLAG_RW | ST_FLAG_STRING, 10,
"UPS.PowerSummary.DelayBeforeShutdown", NULL, DEFAULT_OFFDELAY, HU_FLAG_ABSENT,
NULL},
It is not clear how this value is being used.
