I’ve recently turned my attention to a self hosted app that @matthew919 and I took a look at ages ago. Back then I set it up, which is usually as far as I get with these things ( eg. N8N). But on this occasion I even made use of it.
I hooked it up to prowlarr which was nifty, but I also wired it into a few of my scripts that run routinely at home, like my backups.
Anyway, the push notifications to the companion phone app are top notch and it’s very easy to implement.
If you haven’t heard of it before, I recommend checking it out.
