After Stringify went defunct, I was never particularly happy with how this project functioned. IFTTT was pretty rough at best (it frequently took a while for notifications to arrive, which kind of defeated the whole point of getting/sending them). After IFTTT started charging for more than a couple integrations, I stopped using this project.

THEN I stumbled upon Home Assistant and saw where I wanted to take this and several other projects I have. Took me FAR longer than I would have liked (funny how being responsible for multiple kiddos makes these kind of projects fall by the wayside), but I finally got this project setup with my instance of Home Assistant and it's working smoothly again! Unfortunately my Arlo cameras don't really play nice with Home Assistant, so I can't integrate them as I could with Stringify, but notifications on my phone are completely instant and I'm able to include flashing some lights to get my attention as well. Because I'm using a Xenon and Argon with my setup, the base code on the Xenon didn't really change but I had to add code to my Argon since it's the only one actually on my local network (the Xenon is a Bluetooth only device). I've included that code on Github (I had to manually pair down the code, as I use my Argon for several other projects too). I think it should be functional as-written, but it's always possible I messed up.

While my use of Home Assistant is still somewhat limited, I'm slowly working on using it to replace how I interact with other things in my house (be that purchased 'smart' items or my own creations).
