Hi @TomPark
To start out - I just want to say that Zapier is an amazing platform and as an automations expert I use it for 90% of all of the client work that I do.
However - and I hope I don't get in trouble for this:
In this particular case, Amazon’s Alexa app (Which is free, and you do not need to have a physical Echo or other device to use it) is I believe your best tool here.
Inside the Alexa app you would want to create a “routine” of the type “location”. Set your home location and then a trigger for “leaves”. (When you leave the location).
From there you can setup what you want it to do - play a sound, send a message, etc.
