NetRadio component for Home Assistant

This is a new Media_source for the Home Assistant home automation framework, that allows you to define a set of web radio stations (e.g., http://streams.greenhost.nl:8080/jazz) and then play them from a service call or by using a custom Lovelace card.

To install the Media Source component:

1. Create a netradio folder inside the config/custom_components folder
2. Copy \_\_init__.py, const.py, manifest.json, media_source.py, services.yaml to config/custom_components/netradio
3. Add a configuration in your configuration.yaml file like this.

• URL is the link to the audio stream.
• Name is the user friendly name.
• Icon is a link to a thumbnail image that will be shown in the browser and on the Lovelace card.

netradio:
  radios: 
    - url: 'http://streams.greenhost.nl:8080/jazz'
      name: Concertzender Jazz
    - url: 'http://icestreaming.rai.it/5.mp3'
      name: RAI Radio Classica
      icon: 'https://cdn-profiles.tunein.com/s17167/images/logoq.png?t=153677'
    - url: 'http://stream.srg-ssr.ch/m/rsc_de/mp3_128'
      name: Radio Swiss Classic
    - url: 'http://wshu.streamguys.org/wshu-classical-mp3'
      name: WSHU
    - url: 'https://streams-pfs.kqed.org/kqedradio-pfs?listenerid=cd0bc9c32b46bbe87b06480cabac29f7'
      name: KQED
    - url: 'http://kzsu-streams.stanford.edu/kzsu-1-256.mp3'
      name: KZSU

You can find a lot of network radios in directories like this one: https://www.radio-browser.info/

For added privacy, you can download the icons into a icons directory inside <config>/www and then link those icons as shown below.

netradio:
  radios: 
    - url: 'http://streams.greenhost.nl:8080/jazz'
      name: Concertzender Jazz
      icon: 'http://hassio.local:8123/local/icons/cz.png'
    - url: 'http://icestreaming.rai.it/5.mp3'
      name: RAI Radio Classica
      icon: 'http://hassio.local:8123/local/icons/rai.png'

To install the Custom Lovelace card (optional):

1. Copy netradio-card.js to <config>/www directory
2. Add netradio-card.js to your Lovelace resources (you need to activate advanced mode first), by going to Configuration->Lovelace Dashboards ->Resources->Add resource
3. add "/local/netradio-card.js" as a Javascript Module
4. Add the card in your Lovelace UI by using the following configuration example (replace your media player name):

type: 'custom:netradio-card'
entities:
  - media_player.bang_olufsen

How to use

You can play the radios from the Custom Lovelace Card, the Media Browser panel, or by calling a service:

Media browser

Service calls

There are three service calls

netradio.start_radio

Starts playing a given radio station, with parameters:

entity_id - the media player to play the radio
radio_index - the number of the radio you want to play, starting from 0, in the list above.

netradio.next_radio

Switches to the next radio in the list. Goes back to the first radio when you switch past the last one in the list.

{"entity_id": "media_player.bang_olufsen"}

netradio.prev_radio

Switches to the previous radio in the list.

{"entity_id": "media_player.bang_olufsen"}

Fixing Slow Start Time with Chromecast

If you use Chromecast as a media player for your radios, you may experience that some streams take a long time to start playing (up to 30 seconds or more). This is a bug in Chromecast that Google didn't fix despite bug reports. However there is a workaround: after starting the radio with the netradio.start_radio service, wait 2 or 3 seconds and then call the media_player.media_play service, as shown below. That will kick the Chromecast to actually start playing immediately.
