I went around trying to get a cookie cutter way to get a notification when my cat was at the door using a motion sensor. But since I don’t want to be flooded with notifications I want to make it so the notification is only sent when the door is closed. If the door is open, the cat can come and go as she pleases and I don’t want to have a notification, but if the cat is at the door, I’d like to be notified so I can open the door and let her in. I have no experience programming so I got stuck following the tutorials because I found no way to have the two conditions met before the message being pushed. This is what I have right now. > /\*\* > > - Pet Doorbell > - > - Copyright 2016 Rodrigo Carvajal > - > - Licensed under the Apache License, Version 2.0 (the “License”); you may not use this file except > - in compliance with the License.

You should probably take a look at Rule Machine: > [@Rule machine - as per the app developer, this app is no longer available for new installs, distribution, or support](https://community.smartthings.com/t/release-rule-machine/28730): > > Rule Machine is no longer available. This would be easy using a “Triggered Rule”: Set “motion occurred” as a trigger Set “door closed” as a condition Set “Push message” as the action when true ---
