My Question or Issue

Hey Everybody,

I am currently playing with some smarthome spotify integration. I am trying to connect my aux box with my network and use spotify connect. My problem is that my Network adapter does not have Support for Spotify Connect. So Therefore I wanted to ask if the interface or whatever is needed to have the adapter found by spotify connect is openly accessible. If so where can I find a specification or something? I looked through the documentation but I couln't find any Information on spotify connect.
If I am on a wrong path to solve my problem I am open to other approaches.
Thanks in Advance
