So this is more of a heads up - as of today, 22/May/2024, the TuneIn part of the README is not applicable for newer TuneIn and Sonos App versions. TuneIn removed the ability to add your own radio.
The workaround is to create the station in the web app and add it to Favorites, as explained here:
The Custom URL feature allows you to listen to a private streaming URL, most likely not in the TuneIn directory, using the TuneIn and Sonos app.
To add a custom URL to your Sonos:
Ensure that TuneIn (new) is added on your Sonos app
Log into the iOS or Android TuneIn app using the same TuneIn credentials you use on Sonos
On the TuneIn app, navigate to Library
Tap on customURL and enter the desired stream URL
While listening to that stream, tap the favorite (heart) icon on the now playing screen
Select “favorite station”
Enter a name for the custom stream
Return to TuneIn (new) on your Sonos app, and you should now see that station in your favorites gallery there.
