## How can I use this?
The way I've set it up on my Raspberry Pi 4b is absolutely cursed and there's certainly better ways to do it, but it's 04:34am as I'm clacking my keys right now and I want sleep, so here's my setup:
### TL;DR
- Set up a web server on ports 80 and 443,
- Use `index.php` for every request,
- Redirect `airable.wifiradiofrontier.com` to your proxying device (f.e. via a DNS adblocker such as Pi-hole),
- Play around with the `radios` folder next to `index.php`.
### My setup
The way I've set it up on my Raspberry Pi 4b is absolutely cursed and there's certainly better ways to do it.
- Home Assistant OS
- Yes, I know running custom software outside of addons (which are just neatly packaged docker containers with special rules) isn't supported, but if it works in such a restrictive environment, then it surely works everywhere.
- [linuxserver/nginx](https://docs.linuxserver.io/images/docker-nginx/)
- Easy to set up, supports a wide range of platforms, and I don't need any of the fancyness that comes with linuxserver/swag (certbot) as it sits in my local network.
- The default config uses `index.php` for all requests, which is exactly what we want! Yay!
- Plop `index.php` and the `radios` dir into `www` (or set up a mount for it).
- In your favourite DNS adblocker (Pi-hole or AdGuard Home), redirect `airable.wifiradiofrontier.com` to your device's IP.
- Put a web radio into the radios dir (using my existing config as an example), or create your own:
- Mounted such that `index.php` and the `radios` dir end up as `www`
- AdGuard Home to redirect `airable.wifiradiofrontier.com` to my raspi.
- desktop.json contains a stream hosted using the following:
- [Icecast](https://icecast.org/) or another web radio server
- I'm personally using [AzuraCast](https://www.azuracast.com/), which uses Icecast under the hood, but with arm64 support!
- [butt](https://danielnoethen.de/butt/)
- This is really just if you want to f.e. stream your PC audio to your internet radio.
- ???
- Profit!
**TL;DR: Set up a web server on ports 80 and 443, make it use `index.php` for every request, play around with the `radios` folder.**
## Any hints for following your footsteps?
