Request to add additional attribute_templates to template-based request

Configuration
1

Hello community!

Is it possible to add additional “attribute_templates” to a template-based request?

For example, for this “rest” request:

sensor:
  - platform: rest
	name: deepl_translation_expired
	resource_template: >-
		https://api-free.deepl.com/v2/translate?text={{ states.sensor.packages_expired.attributes.packages[0].status | urlencode }}&target_lang=DE
	method: POST
	headers:
		Content-Type: application/x-www-form-urlencoded
		Authorization: !secret deepl_apikey
	payload: ""
	value_template: "{{ value_json.translations[0].text }}"
	json_attributes:
		- translations
	scan_interval: 300
	verify_ssl: true

I would like to add an “attribute_templates” similar to the one used here.

sensor:
  - platform: template
    sensors:
     morgen_abholung:
      icon_template: "mdi:delete-empty"
      friendly_name: "Morgen Abholung"
      value_template: >-
       {% set mr_states = states('sensor.tage_abholung', 'state')[0]%}
       {% if mr_states == "0" %}1{% elif mr_ststes == "1"%}1{% else %}0{% endif %}
      attribute_templates:
       nächste_abholung: >-
       {{ states('sensor.next_waste_collection_daysto') }}

Use the rest integration rather than the rest sensor platform. That way you can create as many sensors as you want from the one call to the resource.

e.g. (in your configuration.yaml file)

rest:
  - resource_template: >-
		https://api-free.deepl.com/v2/translate?text={{ states.sensor.packages_expired.attributes.packages[0].status | urlencode }}&target_lang=DE
    method: POST
    headers:
		Content-Type: application/x-www-form-urlencoded
		Authorization: !secret deepl_apikey
    sensor:
      - name: "Deepl Translation Expired"
        value_template: "{{ value_json.translations[0].text }}"
      - name: "Another Name Here"
        value_template: "{{ value_json.another.path.here }}"
      - name: "Some Other Name"
        value_template: "{{ value_json.some.other.path }}"

Thank you for the quick solution suggestion!

It’s something different that I need. I simply want additional attributes to be added for the newly created “sensor.deepl_translation_####”, which should be extracted, for example, from “states.sensor.seventeentrack_packages_delivered.attributes.packages[0].location” and added as an attribute to the newly created “sensor.deepl_translation_####”.

Your solution suggestion creates additional new sensors, which is not needed in my case. Unfortunately, your solution suggestion is not working, and errors are displayed after restarting.

The above exception was the direct cause of the following exception:

My solution does not have attributes so I have no idea why you are getting these errors:

I don’t know if I check the status with e.g. {{ states.sensor.seventeentrack_packages_delivered.attributes.packages[0].status }} check i get a positive response.

Is there any way to add more attributes?
