I am one of the few(?) that still uses Squeezebox at home.
Squeezebox is still in active development because of open source and I love the concept and hardware for it. Now it is time to give something back
My HA installation is running on a Intel NUC and has plenty power for other activities such as audio playback.
I have never created an plugin for HA so this is my first. I took the great Spotify connect addon and created the Squeezelite standalone addon.
Note: The plugin does not install Squeezebox server you have to run that somewhere else. Squeezebox server usually runs on a machine that contains all your music, usually that is not your HA-hardware
Add this url to your hass.io addons repos (Supervisor -> Add-on store -> three dots upper right): https://github.com/large/hassio-addons
Reload addons list (three dots upper right).
Install Squeezelite (Shown under Lars Werner Hass.IO Addons Repository).
Due to the lack of script skills, the plugin is only supported with x86/x64 at the moment.
Squeezelite does support ARM so I will update it when I get my hands on a Raspberry PI to test it on.
If you have issues or other comments, please let me known in the issues section!
TIPS if your audio is not correct:
Install Alsa & PulseAudio Fix from resp https://github.com/OPHoperHPO/hassio-addons
Stop your player, start the plugin one time and try to play again. Works fine on my NUC.
