With SmartThings transitioning everything to their new app, there have been quite a few changes lately. For example, many of the SmartApps in the old Classic app are missing.
In my latest video, I give an example of a SmartApp that alerts you when a door is left open. Let’s use this example to show how to find and add this extra SmartApp.

After doing all these steps once it’s much easier to add more smart apps this way. I hope SmartThings improves this.
I didn’t go into detail in the video about all of these steps in case SmartThings does change it soon.
Now you can be notified if a door is left open, and even receive ongoing reminders until the door is shut, which is great.
Hope this helps!
