Door Sensor Trigger SMS/Email alert

I just installed a door sensor to my garage door so I can tell if it is open or not, eventually I am going to add a relay to be able to access it remotely. For now I just want to be notified if the door is left open over an hour. I know how to set up the scene with the trigger of it tripped but when I add in a delay of the scene I have no way of calling a notification action except when the trigger is called but that is at the time of the sensor trip and not after the delay.

I search around google and this forum and I couldn’t find anything about the notification piece, any help would be appreciated.
