How can I realize schedules that work over midnight?

FAQ #101821

When you use BACnet Schedule objects you have to know that the Present Value will be set back to "Schedule Default" at midnight.

This is defined in the BACnet Standard.

The FAQ describes how to deal with that.


The Present Value property will be assigned the value of the Schedule_Default property at 00:00 of any day,
unless there is an entry for 00:00 in effect for that day.

If a scheduled event logically begins on one day and ends on another, an entry at 00:00 shall be placed in the schedule that is in effect for the second day, and for any subsequent days of the event's duration, to ensure the correct result whenever Present_Value is calculated
