Sensational Sonos Sensor Synchronization

Introduction

Wouldn't it be nice to come home and have your music on automatically? And what if you could control the speaker easily, just using your voice?

With such title, you probably have big expectations! It's a relatively simple project though, and the idea was to provide good documentation so anyone with the required hardware could replicate it at home

Well, it's still a work in progress!
But meanwhile you can see this video (recorded after some Spanish wines), in which we explain briefly how it works:

ScreenShot

This project is mainly divided in two parts:

  • The first one consists on running a local API on a Linux-based single-board computer, and fire HTTP requests to the Sonos local API depending on the readings comming from different sensors. The speaker can then play music (or shuffle songs, or change the volume, etc.) based on these events.

  • The second makes it possible to control the speaker using voice commands from an Amazon Echo device.

Requirements

First Part

To trigger actions in your Sonos speaker using data from sensors you will need:

  • Sonos speaker (see the "Notes About the Requirements" below).
  • A WiFi development kit (see the "Notes About the Requirements" below).
  • Grove PIR sensor.
  • Magnetic switch (optional).
  • Orange Pi set, consisting on:
    • Orange Pi One single-board computer
    • 4GB SD Card (8GB is strongly recommended)
    • A decent 5V/2A USB power supply (like this one)
    • A USB to 4.0x1.7mm DC jack cable (like this one)

A developer account on the relayr cloud platform (free) is required to onboard the WiFi sensor node.

Second Part

To control the Sonos speaker using your voice, you will need:

To create and deploy the Alexa skill, a developer account on Amazon (free) and an account in AWS (free but requires confirmation via credit card) are needed.

Notes About the Requirements

This project will work great with any Sonos PLAY:1, PLAY:3 or PLAY:5. It has not been tested in other Sonos devices, but it will likely work well.

As for the single-board computer, the first version of this project has been deployed in an Orange Pi One, but it may work in other Armbian-based boards. More boards will be added soon, including the Raspberry Pi.

Regarding the WiFi development kit, almost any ESP8266-based board will do. In the first version of this project, a WeMos D1 mini has been used due to its low price tag. The codes for the Particle Photon will be added in the future as well.

Installation & Configuration

Single-board Computer

As said, in this project we will be using a Sonos HTTP API (more info on the specific tutorials below), as well as a script to read data from the sensors.

Select your board from the list below, and follow the corresponding tutorial:

  • Orange Pi One (it will probably work with most Armbian-based systems as well)
  • Raspberry Pi (NOT AVAILABLE YET - it will probably work with most Raspbian-based systems as well)

Sensor Node

The next part consists on configuring the sensor node, i.e. a WiFi development kit connected to a set of sensors. In this case, we will use two: A PIR sensor, which detects presence, and a magnetic switch, which will be triggered when the door opens. This node will send the readings to the cloud, so the script running on the single-board computer can retrieve them remotely an fire HTTP requests to the Sonos speaker.

Select your WiFi devkit from the list below, and follow the instructions:

Amazon Echo / Alexa Integration

-----WORK IN PROGRESS-----

To Do

  • Add WeMos D1 mini tutorial on the "sensor node" section.
  • Add Particle Photon tutorial on the "sensor node" section.
  • Add Raspberry Pi tutorial on the "single-board computer" section.
  • Add Amazon Echo / Alexa integration tutorial.
  • OPTIONAL: Create the project structure.
  • OPTIONAL: Create the solution architecture.
