I have setup the below piston to automatically lock my front door 90 seconds after the door is unlock and contact sensor is closed. My understanding is that the default Task Cancellation Policy behavior is to cancel any pending on condition state changes. But in my testing, a pending wait to lock the door task was scheduled when the door is initially unlocked and the door sensor is still closed but wasn’t cancelled, as I expected, when the door sensor became open causing the scheduled task to run when the door was still opened. Am I understanding this correctly?
As a side note, I added a retry notification because my lock sometimes goes in a funky state where it would not respond to lock request until I restart my Smartthings hub.
