Auto Close Garage Door After 15 min open?

Would you mind sharing your piston for this? I have been trying to accomplish a similar thing (reminders every 15 minutes after the first half hour), but am new to Smartthings and CoRE and haven’t been able to figure out the correct code to make it work. I was digging through the piston help thread, but with over 3000 replies and the fact that the search in thread feature appears to not work correctly for me, it has been frustrating to find the answer on my own

No problem. I’ll post it.
