Get notified of motion after initial motion detected

Hey everyone, I’m trying to setup a piston that will notify me when my dogs come back to the door from outside so I know to go let them in. I’m not sure how to arrange the logic in webcore however. Basically, if I open the door (has an open/close sensor on it) and the motion sensor outside detects motion, I would would like to then get notified once the motion sensor detects motion AGAIN (when the dogs return) so that I’m not getting notified every time I open the door. Is this possible?

If your IF qualification is “Motion Sensor changes to Active AND Door is Closed” then the Piston won’t fire when you open the door and cause motion at the same time.
