This is a neat way to use the PI, if you want to avoid BT all together and have access to a web browser on the PI you could also login to Spotify.com and use your phone / watch to manage what is playing but have the output set to the web browser on the PI. This assumes you use Spotify of course =)

I have a similar setup in my workshop and it has been solid for years.

You don't even need a graphical user interface, a web browser or the official Spotify app to accomplish this either - you can use open source projects that use the official Spotify API to create an extra Spotify speaker you can control from Spotify on another phone or PC.

There are loads of these projects, often in docker containers you can launch with a single command:

> https://hub.docker.com/r/flaviostutz/rpi-spotify

> https://github.com/qSharpy/raspotify-docker-compose

> https://github.com/Spotifyd/spotifyd

etc etc.

I've several speakers integrated with various Spotify API based solutions around my home running on various RPi hardware. Some of these projects do even more, like add Airplay streaming too.

Interesting! Combine this with the product(s) from hifi berry and you can relatively cheaply turn any high quality speaker into a standalone. Who needs Sonos.

I'm actually using HifiBerry! They provide a great OS built in partnership with B&O that supports Spotify/Airplay with their devices out of the box:

Check out HiFiBerryOS with their DSP hat and a calibration mic.

Pi + DSP Hat + AIYIMA A07 + decent speakers + Roon (or other) = A fantastic and inexpensive sound system. You could spend 50x as much and not get as good sounding system.

DSP hat + calibration mic is exactly the approach I went with, agreed it is an incredible setup for the money.

All of those use reverse engineered APIs, particularly for playback. Spotify's APIs only support playback through a Web browser (that supports their DRM).

Better yet would be to use spotifyd[0] for this. I tried to set this up with my RPi a while ago but was defeated by Linux audio. Instead I just bought a Sonos. Oh, well.
