Inspired by the Listening report of Last.fm, I want to build my own dashboard of streamed music with the help of Spotify and the last.fm Api, since the last.fm sensor from Home Assistant is not really reliable for me (get a lot of unknown states) and the lastfm Api can grab a lot more information for example the genre of each played song and/or artist. I created two sensors so far that will get me the genre of each Spotify artist that is streamed:
- platform: template
sensors:
get_artist:
friendly_name: Get Spotify Artist
value_template: >
{% if states('media_player.spotify') != 'playing' %}
Pause
{% else %}
{{ states.media_player.spotify.attributes.media_artist |urlencode }}
{% endif %}
And then another sensor that grabs the genre from the last fm API, triggered by an automation when the artist changes on the spotify media player:
- alias: Update Track Genre
trigger:
platform: state
entity_id: sensor.get_artist
action:
- service: homeassistant.update_entity
entity_id: sensor.get_the_genre
- platform: rest
resource_template: http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist={{states.sensor.get_artist.state}}&autocorrect=1&api_key=MYLASTFMAPI&format=json
name: Get The Genre
method: GET
timeout: 60
scan_interval: 86400
value_template: >
{% if states('media_player.spotify') != 'playing' %}
Pause
{% else %}
{{ value_json.artist.tags.tag[0].name | title}}
{% endif %}
All that works fine so far, and I already displayed it in grafana with the really nice discrete plugin:
As far as I know, that’s the only way to display different string states of one sensor in grafana, but now I’m looking for a way to not show this states in a timeline, but in a graph or pie chart like this here:
Does anybody know if that is possible? One way via Home Assistant would be to create a history stats sensor for each genre
- platform: history_stats
name: Genre Heavy Metal
entity_id: sensor.get_the_genre
state: 'Heavy Metal'
type: time
start: '{{ now().replace(hour=0, minute=0, second=0) }}'
end: '{{ now() }}'
but of course, that would be a lot of work since there are thousands of genres listed…
Hope somebody can help! Thanks
