Macchiato

Macchiato is a node.js application which turns your Sonos speakers into a coffe shop. It is meant for those who prefer to code with non-disturbing background noise.

Install & use

$ git clone https://github.com/michaelmcmillan/macchiato
$ node macchiato/macchiato.js 192.168.1.229

 Macchiato

[*] uPnP: SetAVTransportURI
[*] uPnP: Play
[*] Macchiato: Streaming "audio/university.mp3" to speaker 192.168.1.229

Macchiato only takes one argument: The ip address of the speaker you want to use.

Under the hood

By using node's bundled http-library it is pretty easy to communicate with devices from Sonos. I started out by Wiresharking the network to reverse engineer the protocol. This was far from necessary due to blog posts like this. It turns out each speaker acts as a uPnP endpoint.

Macchiato spins up a static file server each time you run it on port 1337. The speakers then stream the audio files straight from Macchiato. This has several benefits: You can add your own audio files (rainy mood etc.) and it will still work without an internet connection.

To-do

If you want to help out please do a pull request. These are some of the things that needs twerking:

• Feature: Show percentage/seconds played of a track
• Improve the user experience
• Use an xml-lib to create the Soap-requests.
• Feature: Choose from a set of sounds.
• Feature: Scan the network for speakers/zones.
• Feature: Adjust volume from the command line.
• Bug: Repeat when file is finished.
