A little help with my first SmartApp please

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.

You should probably take a look at Rule Machine:

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


It’s called a Conditional Trigger, and that’s the way you find it in the app.


I second Rule Machine !

I used to write my own smart apps, not anymore :slight_smile:

Just tied it, it’s amazing.
