Understanding alerts

I am trying to understand alert. Today I left the garage door open for 4 hours. Didn’t know it was, till I saw the light on inside. So my question are

  1. Can alerts be setup so it sends notice every few minutes?
  2. Will this be thru app or email alert
  3. can it also trigger thru alexa to notify every few (set) minutes?

Thanks in advance

There are options to have an alert immediately when door opens and after a preset delay if it remains open. The alerts are delivered via app push notification or email. Use web interface if you prefer email notifications: https://www.garadget.com/my/
