homebridge-rusty-spotify

Spotify plugin for Homebridge written in Rust. The plugin requires a Spotify Premium account.

Installation and Setup

1. Install Homebridge: sudo npm install -g homebridge
2. Install the plugin: sudo npm install -g homebridge-rusty-spotify
3. Register the plugin as app in the Spotify Developer Dashboard
   1. Login
   2. Select "Create a client ID"
   3. Provide a name and description in the pop-up; click "Next"
   4. Copy the "Client ID" and "Client Secret" which will be required in the following configuration step
   5. Click "Edit Settings"
   6. Add http://localhost/callback as "Redirect URI" and save
4. Configure the plugin using the generated client ID and client secret (see Configuration)

Configuration

The generate_config script can be used to generate the config. It requires for the client_id, client_secret and Spotify username needs to be set since those are required to authenticate to the Spotify Web API. To run the script, make sure to have Python 3 and the spotipy library installed.

Running the script will open a web browser asking to authenticate to Spotify which is required to retrieve the refresh_token.

$ ./generate_config --help
usage: generate_config [-h] [--client_id CLIENT_ID]
                       [--client_secret CLIENT_SECRET]
                       [--redirect_uri REDIRECT_URI] [--username USERNAME]

Script to retrieve an access and refresh token for using the Spotify API

optional arguments:
  -h, --help            show this help message and exit
  --client_id CLIENT_ID, --client-id CLIENT_ID
                        Spotify client ID
  --client_secret CLIENT_SECRET, --client-secret CLIENT_SECRET
                        Spotify client secret
  --redirect_uri REDIRECT_URI, --redirect-uri REDIRECT_URI
                        Redirect URI
  --username USERNAME   Spotify username


$ ./generate_config --client_id=<client_id> --client_secret=<client_secret> --username=<username>
  {
    "platform": "Spotify",
    "name": "Spotify",
    "service_type": "light",    // "light" or "speaker"; Speaker is not supported by HomeKit
    "client_id": "<client_id>",
    "client_secret": "<client_secret>",
    "refresh_token": "<refresh_token>"
  }

The generated config needs to copied to the Homebridge config file (e.g. ~/.homebridge/config.json). For example:

//...
"platforms": [
  {
    "platform": "Spotify",
    "name": "Spotify",
    "service_type": "light",    // "light" or "speaker"; Speaker is not supported by HomeKit
    "client_id": "<client_id>",
    "client_secret": "<client_secret>",
    "refresh_token": "<refresh_token>",
  }
]
//...

service_type specifies whether Spotify devices should use the Lightbulb or Speaker service. If service_type is not specified, "light" will be used by default. HomeKit currently does not support Speaker services and will show "This accessory is not certified and may not work reliably with HomeKit".

Usage

Add the plugin in the Home app. The plugin will automatically discover available Spotify devices and add them as accessories. Turning a Spotify accessory on will resume playing music on the device, turning off the accessory will pause the music. The accessory also allows to change the playback volume.

Accessories get refreshed every 10 seconds (or as specified in the configuration file).

Development

1. Install the Rust toolchain, wasm-pack, cargo-generate and npm by following this guide
2. Clone the repository
3. Run make
   • This will create a pkg/ directory containing all the generated nodejs files
4. Copy the generated files to a device/directory that can be discovered by Homebridge
5. Switch to the directory and run npm install to install all required dependencies
6. Run Homebridge in debug mode and specify the directory with the plugin files: DEBUG=* homebridge -D -P /path/to/plugin/homebridge-rusty-spotify
