Good question @Norster! The motion schedule feature is used to prevent alerts during a designated period of time. Once you choose, save, and enable a time frame for motion scheduling, you should not receive alerts during that desired time.
If you have multiple devices or do not have a set schedule to choose from, you might enjoy the motion snooze feature which allows you to quickly snooze alerts from a device for a certain duration of time. I hope this helps!
