@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!
