Hi,
just to confirm, this help resolve the issue with the official component forgetting the devices?
Your component looks like the missing link for us to start streaming Spotify on a Chromecast device. Nice!
I’m getting these log listings:
Setup of platform spotcast is taking over 10 seconds.
ModuleNotFoundError: No module named ‘spotify_token’
Update of sensor.chromecast_devices is taking over 10 seconds
What I did:
- Downloaded the files (as a ZIP from your Github) then copied them to /config/custom_components/spotcast/
- Added my Spotify username and password to configuration.yaml
- Restarted Home Assistant (is Hassio btw)
Can you help me on my way?
Edit: just restarted HA again and the ModuleNotFound error is gone. Now for the other warnings?
Seems your network is slow for some reason. The 10 sec warning can be ignored though
Which official component?
Plus this components main use case is to start spotify on a chromecast device…
You are right. Public Enemy is blasting from my Google Home Mini now

I think @phairplay means that this script should work (but doesn’t when the Chromecast device is off):
play_song:
alias: 'Play a Spotify track on Chromecast'
sequence:
- service: media_player.select_source
data:
entity_id: media_player.spotify
source: 'Living Room'
- service: media_player.play_media
data:
entity_id: media_player.spotify
media_content_type: music
media_content_id: spotify:track:6xFXusME7FMMyMkPrIv2WJ
But with your component this does the trick even with devices that are ‘off’:
- service: spotcast.start
data:
device_name: 'Living Room'
uri: 'spotify:track:6xFXusME7FMMyMkPrIv2WJ'
A question though: when playing a song using spotcast.start, I notice the entity ‘media_player.spotify’ changes state to ‘playing’, but the entity ‘media_player.chromecast_living_room’ remains ‘off’. Any idea why this happens? The automation to turn on my amp depends on that

Some people their spotfiy component retains the devices its can play from.i .e Google home or Google mines.
Yet mine like some others here it forgets them once the devices are off.
Before I moved home and on another wifi network I could have spotify play music directly
In short the answer is that the only way to start spotify on a chromecast device is through this component nowadays. I’m on my phone so I will not detail it but it has to do with the token for the spotify media component is not powerful enough to start the app on chromecast.
sorry to be dumb, but could you please share a working script example?
i have your component working and it sees all my cast devices
I tried this
play_song:
alias: 'Play a Spotify track on Chromecast'
sequence:
- service: spotcast.start
data:
device_name: 'Master Bedroom Speaker'
uri: 'spotify:track:6xFXusME7FMMyMkPrIv2WJ'
yet checking config kicks up an error
You need to check the log for what error it is. I suspect that it is one of the following:
- You have not installed
spotcastcorrectly. Check in devtools-> dev-service ifspotcast.startis listed as a service. - ‘Master Bedroom Speaker’ is not an exact match for the chromecast device. Check the sensor.chromecast_devices for what devices are available
- Your spotify username and or password is incorrect. These should be the same as when you login on https://open.spotify.com
- You don’t have a premium subscription

1, Yes spotcast.start does appear in the dev tool list
2, ‘Master Bedroom Speaker’ was lifted straight from the devices_json:
3, it is correct because the sensor it populated with the list of devices
4, yes I do have a premium account
using the above I posted as a script I get the following error
Invalid config for [script]: expected dict for dictionary value @ data['script']['play_song']['sequence'][0]['data']. Got None
extra keys not allowed @ data['script']['play_song']['sequence'][0]['device_name']. Got 'Master Bedroom Speaker'
extra keys not allowed @ data['script']['play_song']['sequence'][0]['uri']. Got 'spotify:track:6xFXusME7FMMyMkPrIv2WJ'. (See /config/configuration.yaml, line 176). Please check the docs at https://home-assistant.io/components/script/You need two extra spaces in front of the last 2 lines of your script. It is an indentation problem.

Amazing! Haven’t been able to try it yet but it seems my two days foray of setting up and MPD instance and Icecast server simply to start playlists in spotify (which I have used a total of 2 times) was completely in vain! 
Great! On a side note I am checking with core devs who owns media_player.py because I think these should merge. There is one problem in that the official spotify component in HA used normal clientId and client-secret from spotify dev site which is not powerful enough to initiate playback on chromecast devices (hence this small component).
If I am to take over maintenance of that I would be greatful if someone else would join me

you’re kidding me!
I fell foul of the blooming indentation ahhhh!
many thanks
@fondberg thank you for trying to help with my clear stupidity
it does work yet as already mentioned HA doesn’t detect that the google device is playing anything
I also got some, probably silly error:

1, spotcast.start does appear in the dev tool list
2, ‘Wohnzimmer’ is a name used in chromecast.sensor:
3, the sensor it populated with the list of devices (does this mean my spotify credentials are correct?
4, yes I do have a premium account
My configuration.yaml:
spotcast: username: [email protected] password: hidden
My script:
(Please don’t ask me, why sometimes I cannot post here with proper intendation, hence the screenshot)
Sorry for these beginner questions! Thank you for providing this great component!
you need one more indent from - service down
spotify:
alias: 'Spotify'
sequence:
- service: spotcast.start
data:
device_name: 'Wohnzimmer'
uri: 'spotify:playlist:37i9dQZF1DX3yvAYDslnv8'Thanks for your reply!
Added the indents, but still getting the same error.
