Beszel v0.11 has switched to a maintained version of shoutrrr. Just saw the update on github.

I’ve tried them all and I found tandoori worked the best, especially if you want mobile apps. There are a couple options and untare works on both iPhone and Android. It’s what I use daily and my gd can add recipes she likes, and add items to the shopping list.

Shoutrrr works perfectly well with beszel.
