My wife and I use it for our private discussions. We have a high functioning disabled adult daughter which can not live on her own. Anyway, as her caregivers, it gives us a platform to privately discuss different areas which are necessary, but at the same time triggering to her. (For example, she’s very afraid and severely anxious about fire so if we talk about a fire in a business or in the news, it’s there).

Overall, It’s worked perfectly and no issues!

There are other services which should work for you as well. I use one which never requires a regular check in. They even ofter a command line curl or other methods to send your updated IP to it. Think Home Assistant, via a curl or if you have a router with Freshtomator or other which supports such curl, it will work as well.

I’ve been using them for a few years now and never ever had an issue with uptime or otherwise. My use is just as a backup in the event my VPS goes down which hosts Pangolin (VPS).

Others such as noip.com and such do work well also.

I don’t use this software, but if you don’t mind a little local LLM (or a paid one if that’s your thing), this seems to be a pretty nice one:

It does use icecast for the back end.

I use the docker version of the Joplin Server, it syncs with everything I’ve thrown at it which is a laptop, my Android Phone(s) over the years and my Desktop with no issues. It’s super basic so you just set up an account in the self hosted server and then proceed to login using the Synchronization settings in your Joplin App.

If you have any existing data, Make sure to Back it up First!

This is my compose I use. Sub with your values obviously.

And then in the settings for the sync in the app:

To get there, Go to the Tools > Options > Synchronization

Hopefully this will help. :)
