A simple way to get alerts when your doorbell is rung

I just figured out a fairly simple way to get alerts when my doorbell is rung. I have a wired 24v doorbell. I believe many others work the same way as mine: Pushing the doorbell outside triggers a magnetic coil inside that fires a pin to hit the bell. I figured if it’s using magnetic power, then it might work with a z-wave door/window sensor. I took a z-wave door/window sensor and taped it right by the doorbell’s magnetic coil. It works flawlessly. The doorbell ringing affects that coil enough to make the z-wave sensor think that it switched from open to closed. I don’t quite have the know-how to create a smartapp for this, so I just called it a door sensor and set up an alert for when the door sensor opens. So when someone rings the doorbell I get this message, “Doorbell is open”…
