In the previous article, Control Sonos with a easy to use API, we configured a Docker container on a Raspberry Pi 3 to run an easy to use Sonos API. I prefer this solution over writing code on the Photon to control Sonos. Now it is time to let the Photon talk to the API on the PI 3 to load a playlist and start playing or to stop playing at the press of a button.
Just create a new app with the Particle Build IDE and call the app SonosCtrl. Then add the following library: HttpClient. After adding the library, make sure you have the following includes:
To actually use HttpClient to make requests to the Sonos API, you will need some variables of specific types:
You will use the request variable to configure the request. When you configure request, you will need to specify a hostname or an IP address. I used the IP address of my RPi 3 (SonosController above).
To configure request:
The above just sets the port and IP address for the request. We do this in the setup() function. When we press a button, we toggle between playing from a playlist or pausing the Sonos:
By setting the request path appropriately, we can easily load a Sonos playlist or pause. See the GitHub page at https://github.com/jishi/node-sonos-http-api for more paths to use. There is much more you can do! Above, we target a specific Sonos Player (Living Room). As you can see, this is very simple to do and keeps the Particle Photon code cleaner. The code is kept pretty simple so no error handling, logging etc… You can find the full code in the following Gist: https://gist.github.com/gbaeke/9c185e82e7f23c0c4c9d803990d3660f. Have fun!!!
