Spotcast

Home Assistant custom component to start Spotify playback on an idle chromecast device or a Spotify Connect device (thanks to @kleinc80) which means that you can target your automation for chromecast as well as connect devices.

Spotcast implements a cast platform (requires Home Assistant Core 2022.2.0 or later), which enables Google Cast media player entities to play Spotify URI as well as to browse the Spotify library.

This component is not meant to be a full Spotify chromecast media_player but only serves to start the playback. Controlling the chromecast device and the Spotify playback after the initial start is done in their respective components. Because starting playback using the API requires more powerful token the username and password used for browser login is used.

Used by Spotify-Card.

Installation

HACS

This component is easiest installed using HACS.

Manual installation

Copy all files from custom_components/spotcast/ to custom_components/spotcast/ inside your config Home Assistant directory.

Configuration

Minimum Home Assistant version

Spotcast is compatible with any version since 2021.12.0.

Official Spotify Integration

Note that as of v3.5.2 you must also have the official Home Assistant Spotify Integration installed and configured for this custom component to work. This is because it provides the correct device list which has the correct scopes in its token.

Obtaining sp_dc and sp_key cookies

Spotcast uses two cookies to authenticate against Spotify in order to have access to the required services.

To obtain the cookies, these different methods can be used:

Chrome based browser

Settings page

1. Make sure you are connected on https://open.spotify.com
2. Open the url chrome://settings/cookies/detail?site=spotify.com
3. Copy the content from sp_dc and sp_key cookies

Chrome web console

1. Make sure https://open.spotify.com is opened and you are connected

2. Press Command+Option+I (Mac) or Control+Shift+I or F12. This should open the developer tools menu of your browser.

3. Go into the application section

4. In the menu on the left go int Storage/Cookies/open.spotify.com

5. Find the sp_dc and sp_key and copy the values

Firefox based browser

Firefox web console

1. Make sure https://open.spotify.com is opened and you are connected
2. Press Command+Option+I (Mac) or Control+Shift+I or F12. This should open the developer tools menu of your browser.
3. Go into the Storage section. (You might have to click on the right arrows to reveal the section)
4. Select the Cookies sub-menu and then https://open.spotify.com
5. Find the sp_dc and sp_key and copy the values

Other methods

Incognito mode

1. Open a new Incognito window at https://accounts.spotify.com/en/login?continue=https:%2F%2Fopen.spotify.com%2F
2. Open Developer Tools in your browser (might require developer menu to be enabled in some browsers)
3. Login to Spotify
4. Search/Filter for get_access_token in Developer tools under Network.
5. Under cookies for the request save the values for sp_dc and sp_key
6. Close the window without logging out (Otherwise the cookies are made invalid)

Single account

Add the following to your configuration.yaml:

spotcast:
  sp_dc: !secret sp_dc
  sp_key: !secret sp_key
  country: SE #optional, added in 3.6.24

Multiple accounts

Add accounts dict to the configuration and populate with a list of accounts to be able to initiate playback using diffferent accounts than the default.

If you are using v3.5.2 or greater and thus also have the core Spotify Integration installed, then the additional accounts will also need to be added there as well for multiple accounts to work.

spotcast:
  sp_dc: !secret primary_sp_dc
  sp_key: !secret primary_sp_key
  country: SE #optional, added in 3.6.24
  accounts:
    niklas:
      sp_dc: !secret niklas_sp_dc
      sp_key: !secret niklas_sp_key
    ming:
      sp_dc: !secret ming_sp_dc
      sp_key: !secret ming_sp_key

Edit secrets.yaml

Please note: configuration.yaml is a plain text file and it is not recommended to store your passwords in this file.

By using the !secret tag you are directing Home Assistant to look inside the secrets.yaml file for your key instead.

For a single account add the following to your secrets.yaml file:

sp_dc: [your sp_dc here]
sp_key: [your sp_key here]

For multiple accounts add the corresponding entries to your secrets.yaml file. For example, using the same accounts as above:

primary_sp_dc: [your sp_dc here]
primary_sp_key: [your sp_key here]
niklas_sp_dc: [niklas sp_dc here]
niklas_sp_key: [niklas sp_key here]
ming_sp_dc: [ming sp_dc here]
ming_sp_key: [ming sp_key here]

Call the service

The spotcast custom component creates a service called 'spotcast.start' in Home Assistant.

Start playback on Spotify connect device

{
  "spotify_device_id" : "ab123c5d7347324c2b1234567890f8d6dc40350",
  "uri" : "spotify:playlist:37i9dQZF1DX3yvAYDslnv8",
  "random_song": true
}

Start playback on a device with default account

{
  "device_name" : "Kök",
  "uri" : "spotify:playlist:37i9dQZF1DX3yvAYDslnv8",
  "random_song": true
}

where:

• spotify_device_id is the device ID of the Spotify Connect device
• device_name is the friendly name of the chromecast device
• uri is the Spotify uri, supports all uris including track (limit to one track)
• search is a search query to resolve into a uri. This parameter will be overlooked if a uri is provided
• category let spotify pick a random playlist inside a given category
• country restrict country to use when looking for playlists inside a category
• limit restrict number of playlists to return when looking in a category. Note that only a single playlist will be chosen randomly from them.
• random_song optional parameter that starts the playback at a random position in the playlist
• repeat optional parameter that repeats the playlist/track
• shuffle optional parameter to set shuffle mode for playback
• offset optional parameter to set offset mode for playback. 0 is the first song

Optionally you can specify the entity_id of an existing Home Assistant chromecast media-player like:

{
  "entity_id" : "media_player.vardagsrum",
  "uri" : "spotify:playlist:37i9dQZF1DX3yvAYDslnv8"
}

Find Spotify Device ID

To use the Spotcast service with a Spotify Connect device, you need the spotify_device_id. To find the spotify_device_id, multiple option are available.

With Spotify developper portal

1. Go to Spotify developper console
2. Click GET TOKEN
   
3. Select user-read-playback-state as a scope
   
4. If prompt give permission to your Spotify profile
5. For chromecast devices, make sure to play media on the device prior to checking the logs as they will not show unless active
6. Press the option Try it
7. Read the result in the console in the right.
   

Through Spotcast log

1. Enable the debug logs (instructions are in section Enabling Debug Log in this README)
2. Reboot Home Assistant
3. Go to Configuration >> Logs >> Load Full Home Assistant Log.
4. For chromecast devices, make sure to play media on the device prior to checking the logs as they will not show unless active
5. Find the log entry get_spotify_devices and look for the device ID.

Sonos Device ID

1. Open the Spotify Web Player and sign in if needed
2. Make sure you see your Sonos devices in the Connect popup
3. Open your browser's DevTools (F12 for Chrome)
4. Navigate to the Network tab
5. Connect to the desired Sonos device in the Web Player
6. Find the associated request in your DevTools
7. The request URL looks something like this: https://gew1-spclient.spotify.com/connect-state/v1/connect/transfer/from/my_web_player_device_id/to/my_sonos_device_id
8. The my_sonos_device_id is the spotify_device_id you are looking for.

Transfer current playback for the account

Omitting uri will transfer the playback to the specified device.

{
  "device_name" : "Högtalare uppe"
}

Use the parameter force_playback to continue the user's playback even if nothing is currently playing.

{
  "device_name" : "MultiRoom",
  "force_playback" : true
}

where:

• device_name is the friendly name of the chromecast
• force_playback (optional) true or false, true to continue the user's playback even if nothing is currently playing

Start playback on a device with non default account

{
  "account":"niklas",
  "device_name" : "Kök",
  "uri" : "spotify:playlist:37i9dQZF1DX3yvAYDslnv8"
}

where:

• account is the name of account key in the accounts dictionary in the configuration
• device_name is the friendly name of the chromecast
• uri is the Spotify uri, supports all uris including track (limit to one track)

start podcast playack

Play the latest episode of a given podcast show.

{
  "account":"niklas",
  "device_name" : "Kök",
  "uri" : "spotify:show:6PeAI9SHRZhghU7NRPXvT3",
  "ignore_fully_played": true
}

where

• account is the name of account key in the accounts dictionary in the configuration
• device_name is the friendly name of the Chromecast
• uri is the spotify uri, (podcasts use the 'show' uri)
• ignore_fully_played (optional) true or false, true to ignore already fully played episodes (defaults to false and play the latest released episode)

Use the sensor

The sensor has the discovered chromecasts as both json and an array of objects. Since v3.4.0 it does not do its own discovery but relies on data from core cast. Add the following to the sensor section of the configuration:

sensor:
  - platform: spotcast
    country: SE

The country tag was added in v3.6.24. This tag is optional. If ommited or if you haven't updated the configuration since the update, it will default to "SE" (which it always did before)

Sensor name:

sensor.chromecast_devices

Attributes

devices_json: [
  {
    "name": "Kök",
    "cast_type": "audio",
    "model_name": "Google Home",
