I created a package file to bundle up all of the sensors plus device tracker automation I’ve created, based on the information provided in this thread, and tossed it up on GitHub as a Gist.
The markdown file explains how to install it, and how to enable the Package function in Home Assistant if you haven’t already.
I figure this is the next best thing to an actual integration in Home Assistant, since I keep bouncing off the Python every time I try to write one. I can’t quite wrap my head around dealing with asyncio objects.
