Thank you, that is really helpful. It appears that the Chromecast devices are not registered with Spotify Connect ZeroConf, as proven by the IP address of localhost and the IsDynamicDevice = true.
Supporting Chromecast will require similar processing as I do for Sonos devices, which will be a big effort to implement and support. This is not something I would attempt without having a device to test with.
@thlucas I ask you because you have always been kind in helping me. You are doing a great job, and for months I have switched to using Spotify Plus as well as Soundtouch Plus. Now I am confused again. I see updates on Spotcast, and on the original Spotify applications. I have generated many duplicate things, I wonder what is the best solution for me. In the end I am simply interested in being able to start music from spotify on google home, for a lullaby routine for my daughter, everything else I do by voice. I think that only spotcast allows me this, right? Sorry for the trivial question and outside of your automation, but if I understood correctly, this possibility is not on spotify plus, in fact after deleting spotcast, I could no longer obtain this. Correct?
For the same reason, even your beautiful new spotify card, does not show me the google home devices, but only those associated with spotify connect, right?
@Diegocampy Not a problem, happy to help.
Chromecast devices are currently not fully supported by the SpotifyPlus integration. You can perform player functions (e.g. pause, resume, next track, etc) if the device is the currently active player, but you can’t wake up a device or initiate play of tracks / context.
This has been one of the most requested features, and I would love to provide support for these devices. The problem is that I do not have any Chromecast devices to test with, so I am not able to develop a solution.
If it were me, I would continue using the SpotCast features. I saw a post on the community forum about SpotCast V5 that might be of interest to you as well; it sounds like it’s a new version of SpotCast, though I am not familiar enough with SpotCast to know what it adds or replaces.
Hope it helps!
yes i saw it and i’m trying it. Now i remember how i got to spotify plus, it was the only way to continue playing spotify from my account on my bose soundtouch.
For my needs i will have to continue using spotify plus, spotcast, and soundtouch plus 
maybe i will be able to abandon the official version of spotify one day, just in case i leave it there now
When i use Get Current Users Profile, i always get Login ID as my username as string. It is not canonical (like 31l77y75hfnhk79f7gk6jkk878mg) as you mentioned. It is only the username without the @ mail address part. Should i use this username as my LoginID?
@febalci
Note that for some Spotify accounts, the LoginId and Username values are the same. Not sure why that is, as it’s a Spotify internals kind of thing.
The LoginId value can easily be found using the Spotify Developer Web portal, using the Get Current Users profile service. Click on the Try It button, then find the id response value.
The id response value will be the LoginId value.
@thlucas as mentioned earlier in this thread, I have an entirely Chromecast-based ecosystem. I have been looking for this type integration and dashboard panel for Spotify since I started using Home Assistant 4+ years ago. You noted that you do not have any Chromecast devices, however, depending on your model, the Bose Soundtouch may already support it: Chromecast Built-in FAQ | Bose. If you do work on Chromecast support at any point, I’d be glad to help with testing. Thanks, again, for developing this amazing and much needed integration.
Hello everyone, joining this thread as I’m currently struggling with my Spotify Connect integration.
But it’s not clear to me if Spotify Plus integration can solve my issue. I need advice from you, the awesome community
I’m running my HA on a RPI, with a Jack cable connected to my sound system. My goal is to see my HA instance/RPI as a Spotify Connect device. Thus, it would allow me to play music from Spotify Connect directly on my sound system.
Is it something doable with Spotify Plus?
Thanks a lot for your help
@rml
Chromecast is only supported on the newer Bose Smart products; it is not supported on the older SoundTouch line of products, which is what I have.
Thanks for the info though-good stuff to know.
@Thompop
Check out the SpotifyConnect AddOn, which does exactly what you are asking for.
That should make your RPi show as a Spotify Connect device, which can be controlled by SpotifyPlus, HA Spotify, or even the Spotify mobile / desktop apps.
Hope it helps!
Sorry folks, but I have some disappointing news from the Spotify Developer API camp. It turns out Spotify has decided to remove the following functionality without any sort of warning or grace period. This was announced on the Spotify Developer Forum Blog on Thursday November 27th 2024 (US Thanksgiving holiday - definitely nothing worth giving thanks for IMHO!).
The Spotify Web API will no longer be able to access or use the following endpoints and functionality in third-party applications (SpotifyPlus being one of them):
SimpleTrack object)What these changes mean for the SpotifyPlus Integration and SpotifyPlus Card Dashboard users is that the corresponding functions that access the above features will no longer work, and in most case will return an error message.
You can make your voice and opinion be heard by posting a reply on the Spotify Community Forum. Let them know that this change is not acceptable and how disappointed you are. Please be respectful in the process; scream and shout with your internal voice if you have to (like I did). 
I currently have no plans to try an re-implement the affected functionality, as the deprecated Spotify Web API functions were the only way to retrieve the information. It’s proprietary data, and if they don’t want to share then that’s their prerogative.
Spotify is still a great platform for music streaming, but they lost a lot of respect from me today as a Spotify Champion and user of their Spotify Web API. As a developer of numerous API’s myself, it’s unheard of to simply shut off a feature or endpoint without giving some sort of notice or grace period; and we definitely don’t make major changes like this over a major holiday! IMHO, they totally dropped the ball on this one, not to mention dropped the hammer on numerous developers!
Just thought that you would want to know, and sorry to be the bearer of bad news. I will cross-post this in the SpotifyPlus Card community forum post as well.
FYI - just released a new version of the SpotifyPlus integration
Be sure to check out the SpotifyPlus Card Dashboard as well.
[ 1.0.67 ] - 2024/12/02
spotifywebapiPython package requirement to version 1.0.22.spotifywebapiPython package will now return an exception due to the functions being deprecated by the Spotify development team. More information can be found on the Spotify Developer Forum Blog post that was conveyed on November 27, 2024. The following methods will now raise a SpotifyApiError exception due to the Spotify development team changes: GetArtistRelatedArtists, GetTrackRecommendations, GetTrackAudioFeatures, GetFeaturedPlaylists, GetCategoryPlaylists, GetGenres. The following properties were also marked as deprecated for the same reason: TrackSimplified.PreviewUrl.SpotifyClient.GetPlaylist and SpotifyClient.GetPlaylistItems methods for Spotify-owned / generated content (e.g. “Made For You”, etc). A 404 - Not Found error will be returned when trying to retrieve information for these playlist types.
