Does Home Assistant support Apprise notifications? For my automation system I have a box where you can enter an Apprise target, and get notified with the nfty.sh app.

It's really nice because the channel name is the password, there's no API key or sign up needed.

I like Zrok a lot for true remote access, it seems to do something similar to what tailscale is doing there, but it's powered by some decentralized tech that seems to leave open the possibility of having the tunnel endpoint in a phone app so it still works on isolated LANs.

Of course this is all theoretical, since in practice I keep my personal everyday practical tech a bit more off the shelf, I just put a YoLink vibration sensor on the dryer.
