Notify If Door Is Open for X minutes? (2017)

First post. If this is question is inappropriate for this sub forum please forgive.

Have a garage door sensor installed and connected to ST2 hub. It’s a simple open/close device.
I need to send notifications via text if the door is open for 10 minutes. Bonus points for only notifying if my presence is not detected.
Using IFTTT the notification part is no problem. The problem is the waiting X minutes before sending the notification.
I’ve been searching for a while on how to accomplish this and haven’t found anything. It doesn’t seem like a complicated task but I’m lost.
Any advice to push me toward a solution would be appreciated.
Thanks!

CoRE (now WebCore) is a very powerful community – created rules engine for SmartThings. It allows you to set up stacked conditionals like “If A then B but only while C and not if D.” Setting it up can be quite complex, but there are many community members who will be glad to help you. For example, here is a piston that one member created to notify him if the dog had already been fed twice that day and he picked up the dog bowl for a third time. He needed this because he has a large family and people didn’t always remember whose turn it was to feed the dog.

This allows for flexibility and an architecture that requires more memory than is av…
