Install SpotCast for Home Assistant

I was looking for a way to easily add the playback of Spotify into my automations. I struggled a little with media_player.play_media on various devices, it was just not very reliable for me. Fortunately, I stumbled upon an integration named SpotCast. SpotCast seems to have originally been intended for playback on ChromeCast devices but it seems to work quite fine for playback on any device I have that can link with Spotify.

This guide will show you how to enable and use SpotCast within your Home Assistant instance.

A couple of pre-requisites before we start:

Now lets get going.

  1. Install the SpotCast Integration

Open the Add-ons menu item from HACS

Find the SpotCast Integration

Download the Integration

The SpotCast Integration is now installed, but that’s the easy bit. Next comes the configuration.

2. Get the sp_dc and sp_key details from Spotify.

Open a new incognito window in chrome to – Log in with your Spotify account details.

Press F12 to open the developer tools option.

Find the application setting and under storage select cookies for the URL. Take a note of the sp_key and sp_dc entries. Perhaps paste them into notepad.

3. Add the keys within file editor

Open File Editor within Home Assistant

Add the following entry to config and click save

  sp_dc: !secret sp_dc
  sp_key: !secret sp_key

Now Open secrets.yaml and add the below code – replacing the sp_key and sp_dc with those you took note of earlier.

Remember to click save once completed

sp_dc: my_long_sp_dc_is_pasted_instead_of_this
sp_key: my_sp_key_is_pasted_instead _of_this

Restart Home Assistant to load the new yaml entries.

4. Add to an Automation

For this you will need to go back to and open the playlist you would like to automate to start playing.

Click the 3 dots next to the playlist name and select share > copy link to playlist. paste the link into notepad so you don’t lose it.

Create your automation. Within the actions add ‘Call Service’ and switch to yaml. Add the below code

service: spotcast.start
  device_name: mydevicename
  uri: spotify:playlist:2dzijXtMQRjE8EWRG8QoXD?si=49791c0d59aa447e
  random_song: true
  shuffle: true
  limit: 20
  force_playback: true
  repeat: "off"
  offset: 0
  ignore_fully_played: false


device_name would be the name of your spotify device. I have found all chromecast and spotify enabled speakers or media devices work for this.

The uri is the playlist you copied the link to share. Notice that you only need the end section of the shared URL. in this example the shared URL copied was I have made bold the section you need.

I have set random_song to true. if you set false the playlist will play in order. I have also enabled shuffle, you may have other requirements.

Switch back from yaml to visual editor and you should see something similar to the below. You might find this view easier to continue to tweak settings.

That’s the end of the guide. Hopefully you find this useful.
