I think it is all going to depend on your original source for your stream. Are you going to use something external like Logitech Media server or are you trying to use the Built in Alexa Spotify?
Either can work But they both have advantages/disadvantages
Here’s an easier way:
There is an existing Alexa service on IFTTT that you can use as your “If this”. Just select “Say a specific phrase”. You must have the IFTTT skill enabled on your Alexa for this to work.
You can then use the Webhooks service to trigger whatever it is you want to do in HA. You just pass it through a URL.
Here’s some more documentation on this: https://home-assistant.io/components/ifttt/
It’s a bit outdated (maybe I can figure out how to edit it and update it sometime this week). Just know that the “maker” service no longer exists, it’s now split into two different services, one of which is Webhooks.
Edit: I should also note that you need to be able to securely access your HA server remotely for this to work.
My first choice is Built in Alexa Spotify… but there is no possibility, I can choose local stream, Logitech Media Server or Plex… I also read something about PiMusicBox (Mopidy).
How can I do this? Do you have any idea?
I’m totally knackered so I may have totally misunderstood what you’re asking, so I won’t be offended if you tell me to shut up…
8 steps of happiness :
Yes. That’s what I wanted but how I can stream Spotify on CC? Can you help me with a script example or something?
are you planning on using 1 Alexa device to control all of them or are you trying to use 1 alexa device as the main “music hub”. This is how I did it. Just so you know the only real downfall is that there is about a 3-6 second lag depending on how you have it setup.
With either way you are going to need access to a media server:
If you are going to control the Spotify playlist from your phone of from Logitech media server then all you will need is a streaming URL with an MP3 or OGG section.
so just to recap, to use home assistant with chromecast audio you NEED some type of streaming URL that is in an audio format (MP3 ,OGG, etc…) and then there are multiple ways to execute, but first see how you want to implement the url.
This is what I ended up with
https://community.home-assistant.io/t/need-help-chromecast-audio-media-center-plex-kodi/12361
or
I don’t use Spotify, but this thread is possibly relevant…
What are you using instead Spotify? Maybe I can adapt it somehow… 
Radio stations and local mp3’s.
Can you give me please an example of configuration for 2 streams (localstreams)? I’am interested specifically in how I cast the stream to Chromecast…
I don’t understand what you mean by local streams, but my configuration is all on my GitHub. The package for the chromecast radio is probably the best example,which was adapted from this thread…
I tried different settings to setup a radio stream (http://80.86.106.143:9128/rockfm.aacp) for 1 chromecast but the HomeAssistant is crashing. Can you please help me with the configuration for this radio stream?
My chromecast entity_id is codis_chromecast and I want to create a stream called ‘Rock Stream’.
This is my configuration.yaml, and the HASS is down… it can’t be accessed anymore.

Thanks!
^ what he said, spacing on the script is way out.
Plus you need to ensure that you have the relevant automations in your automations.yaml file.
Hope this helps.
What should I have in automation.yaml? Now is empty… just ‘[]’.
You need an automation that triggers when the input_select is selected, that fires the script.
You may also need one that changes volume, depending on how you’re setting up your player.
Thanks for your reply. I have intended properly the code in this section. But I still have an error:

you need to use the spacebar and not use the tab button for all of the coding you do in home assistant
I recommend simplifying first, that case you can expand your script piece by piece and find out were it goes wrong.
If I understand correctly, you only have 1 Chromecast device? If yes, you can lose the if statement on the entity_id part.
Start with this:
script:
radio538:
alias: Play Radio on Chromecast Audio
sequence:
- service: media_player.play_media
data_template:
entity_id: media_player.codis_chromecast
media_content_id: >
{% if is_state("input_select.radio_station", "Rock FM") %} http://80.86.106.143:9128/rockfm.aacp
{% elif is_state("input_select.radio_station", "Radio ZU") %} http://77.81.25.2:9123/radiozu.aacp
{% endif %}
media_content_type: 'audio/mp4'You did setup your input_select.radio_station correctly?
How do you execute your script? Manual through the frontend?
Hi, many thanks for your help. Currently, I want to execute the script manually through the frontend, but I will want to create an automation to open the chromecast and start the stream.
Here is my setup for input_select:
input_select:
radio_station:
name: 'Select Radio Station:'
options:
- Rock FM
- Radio ZU
chromecast_radio:
name: 'Select Speakers:'
options:
- Livingroom
initial: Everywhere
icon: mdi:speaker-wireless
