I need some help with a couple of rules that perform as I expect most of the time.
The descriptions below are as I think things will work but clearly there are things that I do not understand and wish to get a better understanding of.
The UtilityFanSch app is intended to enable the switch UtilityFanAuto between two configurable times and for the UtilityFanControl to automatically control the fan when humidity is outside the parameters set.
This has worked well until yesterday when:
UtilityFanAuto was switched off at 18:30:00.432
UtilityFan was switched on at 18:30:01.007 and 18:30:01.013
UtilityFanAppOn was switched on at 18:30:00.841
The result being that the utility fan stayed on (uncontrolled) until my system changed to Night mode at 23:00.
Looking at the UtilityFanControl app I guess that it was about to switch on the fan when UtilityFanAuto was switched off.
How can I change the rules to be more defensive or in fact 'correct'.
Many thanks for all advice.
Chris
