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.

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.

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:

• Using Chrome

• Open url chrome://settings/cookies/detail?site=spotify.com
• If no cookies appear go to https://open.spotify.com and sign-in
• Copy content from sp_dc and sp_key cookies

• Using another browser

• Use a browser extension like "Export cookies" and look for sp_dc and sp_key cookies

or

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

• Alternatively you can use a browser plugin like "Export cookies".

    niklas:
      sp_dc: !secret niklas_sp_dc

Use the sensor

The sensor has the discovered chromecasts as both json and since v.2.1 as 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

Sensor name

sensor.chromecast_devices

Attributes

devices_json: [{"name": "Kök", "cast_type": "audio", "model_name": "Google Home", "uuid": "xxxxx", "manufacturer": "Google Inc."}, {"name": "Högtalare uppe", "cast_type": "group", "model_name": "Google Cast Group", "uuid": "xxxx", "manufacturer": "Google Inc."}, {"name": "Vardagsrum", "cast_type": "cast", "model_name": "HK Citation 300", "uuid": "xxxx", "manufacturer": "Harman Kardon"}]
