I have a motion detector on my front porch so I know when someone (or something in the case of our cats) is at the front door. The problem I have is that the SmartThings detector (latest one) detects motion/no-motion very quickly such that I get multiple notifications within a minute when people come to the door or leave. I would like to reduce the number of notifications to one per configurable time (a minute or two). I can think of two ways to do this, either change the sensor itself or via a SmartApp. Does this exist, or am I forced to figure out how to write a SmartApp to do this?
