Controlling Sonos from a Particle Photon

Now for something fun! Let’s control a Sonos from a Particle Photon and a connected button. I connected a Grove Button to the Particle with simple male-to-female wires. The SIG line on the button should go to a digital port (D0 in my case). When the button is pressed, the port will read HIGH and otherwise LOW.

Controlling Sonos is another matter though. Sonos should really make simple APIs available and/or provide access through IFTTT and similar services. Until they do that, you will need to control Sonos the hard way, by connecting directly to it from the Particle and sending commands over their HTTP interface. Luckily, the people from Hover Labs, have some code on GitHub that you can build upon. I simply copied their code in my Particle app and removed references to the Hover device. By the way, the Hover is a cool device in its own right that you should definitely check out as well!

In the above snippet, you see part to the loop() code that checks for a button press. Since we want to toggle between Sonos PLAY and PAUSE, there’s some code for that. The hard work is done by the sonos() function which takes commands like PLAY, PAUSE, NEXT, PREVIOUS. You can check out the full code in the following gist: https://gist.github.com/gbaeke/240fb221204ff828dec06150014ec5fd. Note that the code also contains the LED and photoresitor code from earlier examples. The Sonos control is also very basic as it only implements PLAY and PAUSE so you need something in the queue. But at least you have a start to create more complex interactions.

You could also create a Particle Function that executes the Sonos code which would enable you to control your Sonos from the cloud and even connect this with other services via IFTTT. For instance, you could start playing your Sonos when you are arriving home.

Have fun controlling Sonos from your Particle!!!
