I currently have a shell command that gets a playing status from a music streamer and wanted to know how I could parse the url to the album art image to display it on my lovelace dasboard.

#

shell command:
  cider_now_playing: "curl -X GET 'http://192.168.1.177:10767/api/v1/playback/now-playing' -H 'apptoken: ew6k8q2vdql4c2ewg6pey7r6'"

output

Can you capture that JSON output in a variable eg. value_json? Then the path to the URL would be value_json.info.artwork.url.

#

Looks like you need a REST sensor

#

What would the config look like for that. I was having issues getting the template right

fast storm Mar 17, 2025, 6:53 PM

#

docs that explain are here: https://www.home-assistant.io/integrations/sensor.rest/

#

specify the resource, the headers, and the template in value_template as mentioned above

bitter karma Mar 17, 2025, 8:44 PM

#

I have an entity with attributes now but am having issues specifying the right attribute, when I ue this I get null and get a result type of dictionary ```{{state_attr('sensor.cider_now_playing', 'attributes') }}

#

Here is my sensor.yaml config ```yaml

platform: command_line
name: Cider Now Playing
command: >
curl -H "Authorization: {{ states('input_text.cider_token_macbook_pro') }}"
-H "Content-Type: application/json"
http://192.168.1.177:10767/api/v1/playback/now-playing
value_template: "{{ value_json.is_playing }}"
json_attributes:
- info
platform: template
sensors:
cider_album_art:
friendly_name: "Cider Album Art"
value_template: >
{% if state_attr('sensor.cider_now_playing', 'info') and
state_attr('sensor.cider_now_playing', 'info').artwork %}
{{ state_attr('sensor.cider_now_playing', 'info').artwork.url }}
{% else %}
None
{% endif %}

#

The album art url oneisn't getting anything just yet

fast storm Mar 17, 2025, 8:46 PM

#

That's not a rest sensor

#

But okay

#

Does that attribute have the fields you're referencing?

bitter karma Mar 17, 2025, 8:48 PM

#

I think so

fast storm Mar 17, 2025, 8:51 PM

#

I suggest trying it in devtools -> Templates

#

and states can only be 255 characters

bitter karma Mar 17, 2025, 8:52 PM

#

Ok

#

I wonder if it would be better to not have a sensor and just have an automation use a template to download the image

fast storm Mar 17, 2025, 8:54 PM

#

I don't see how you could do that

bitter karma Mar 17, 2025, 9:16 PM

#

  name: Cider Now Playing
  resource: "http://192.168.1.177:10767/api/v1/playback/now-playing"
  method: GET
  headers:
    Authorization: "{{ states('input_text.cider_token_macbook_pro') }}"
  value_template: "{{ value_json.status }}"  
  json_attributes:
    - info``` I tried giving my hand at a rest sensor but I only get a friendly name attribute

fast storm Mar 17, 2025, 9:21 PM

#

you were passing the content-type before, and now you're not

#

I don't know if that matters, but it's different

#

you can also review the HA logs

#

comment out the second template sensor while you're working on the REST sensor

bitter karma Mar 17, 2025, 9:25 PM

#

ok

#

i tried to give them both unique ids, so I could see them both but that wasn't working quite right

fast storm Mar 17, 2025, 9:28 PM

#

you also said this in the beginning:

-H 'apptoken: ew6k8q2vdql4c2ewg6pey7r6'"

#

you're not using that
