If the garage door is left open for more than 15 minutes, you will receive a push notification to your smartphone. You will keep receiving this notification every 15 minutes until the door is closed or you turn off the reminder from the “Settings” page.

If you don't want the App to remind you every 15 minutes that the Door is Open then you can enable Snooze Open Door Reminder and select between 1 - 12 hours to snooze the reminder.
