Multi Zone Chromecast Web Radio

Configuration
1

I am fairly new with all of this and I have come to a roadblock with my limited experience.

The idea is to have two input_selects, one to pick the location of the chromecast and one to pick a radio station to stream

Untitled.png1005×675 27 KB

My input-selects looks like this

radio_station:
  name: Radio Station
  options:
    - "-"
    - Hot108
    - The Beat
  initial: "-"
  icon: mdi:radio

radio_station_location:
  name: Radio Location
  options:
    - Kitchen
    - Backyard
  initial: "Kitchen"
  icon: mdi:radio

and my radio automation looks like this:

alias: Radio
trigger:
  platform: state
  entity_id: input_select.radio_station
action:
  - service: script.turn_on
    data_template:
      entity_id:
        - service: media_player.play_media
          data_template:
            entity_id: >
              {% if input_select.radio_station_location == 'Kitchen' %}
                media_player.kitchen
              {%-elif input_select.radio_station_location == 'Backyard' %}
                media_player.backyard
              {% endif %}
            media_content_id: >
              {% if input_select.radio_station == 'Hot108' %}
                "http://jbmedia-edge1.cdnstream.com:80/hot108"
              {%-elif input_select.radio_station == 'The Beat' %}
                "http://live.leanstream.co/CKBTFM-MP3"
              {% endif %}
            media_content_type: 'audio/mp3'
  - service: input_select.select_option
    data:
      entity_id: input_select.radio_station
      option: "-"

and when I attempt to actually use it I see a large error:

I have hit a complete road block as to what the next step is.

Use:
{% if is_state('input_select.radio_station_location', 'Kitchen') %}

Edit:
Go to your_ip:8123/dev-template to validate and debug a template

This is my script (which works well):

Like Daniel said, your “IF/ELSE” statement is implemented wrong.

Thank you for the help everyone. I have made a bunch of changes and I have had some good luck. Switching the location and picking a radio station plays the first selection “hot108” no matter what radio station I pick. Both locations are like this.

trigger:
  platform: state
  entity_id: input_select.radio_station
action:
  - service: media_player.play_media
    data_template:
      entity_id: >
        {% if is_state('input_select.radio_station_location', 'Kitchen') %}
          media_player.kitchen
        {% elif is_state('input_select.radio_station_location', 'Backyard') %}
          media_player.backyard
        {% endif %}
      media_content_id: >
        {% if 'input_select.radio_station', 'Hot108' %}
          http://jbmedia-edge1.cdnstream.com:80/hot108
        {% elif 'input_select.radio_station', 'The Beat' %}
          http://live.leanstream.co/CKBTFM-MP3
        {% endif %}
      media_content_type: 'audio/mp3'

I am soooo close haha.

Does it help if you use " instead of ’ ?

Update: looks like you didn’t change your if/else syntax on the media_content_id part (is_state):wink:

You guys are beautiful.

          media_player.kitchen
        {% elif is_state('input_select.radio_station_location', 'Backyard') %}
          media_player.backyard
        {% endif %}

        {% endif %}
      media_content_type: 'audio/mp3'

This works fantastic.

You should do a full write up of your configs in the Share Your Projects section. I’m sure people will love it; I know I would.

I’m going to give something like this a try in the near future, just from seeing it. I never thought about doing the input switch in the same framework as the streaming source. Really makes sense.

I cant seem to get the radio working on my chromecast A, is there something special I need to do?
(Im thinking that my rasp is on wired network, thats causing the problem?)

My pi is also wired and I have had no issues in that regard. I have auto discover turned off but made sure I set a static IP in my router to each Chromecast audio. Then just added the typical lines to my config

platform: cast
host: 192.168.X.X

I made my chrome static, and it seem to work, thanks, great radio :smiley:
