The ability to control what the sensors do and when:
DISARMED mode: Sensors do NOT send notifications
DISARMED mode: Option to have an entry chime play on the base or doorbell when sensor is opened
Scheduled ARM/DISARM/HOME mode: Ability to set times for alarm settings to auto arm/home/or disarm
This could have easily been accomplished if they included the security monitoring into their scheduling/device trigger functionality of the app. This should have been a design requirement.
