If you manually change the mode after setting the schedule, then it will revert to manual mode, and ignore the schedule.
To get it back in to schedule mode, turn the schedule off, and then on again.
The mode will only change at scheduled times, and not at the application of a schedule.
If the current time is 2pm.
I am currently in away mode (receiving alerts)
I set a schedule where alerts are not sent from 8am to 5pm every day
The mode will not change to home (not receiving alerts) until the NEXT DAY when it is scheduled to change home mode at 8am.
If the schedule is manually adjusted before that (I change it to home mode), then it won’t change at all, because the schedule will be toggled off.
