As a user, I can pass a variable { input_text.some_text} in the resource field of the REST sensor in my configuration.yaml so that I can make the integration more dynamic with HA
Below is a concrete example:
Current situation:
I am having a REST sensor that fetches the information about the gasoline station in a certain radius around my home’s position where the price is the most affordable.
I can’t seem to be able to pass any variable in the query parameters of the resource endpoint.
- platform: rest
name: Cheapest Diesel around me
unique_id: cheapest_diesel_around_me
resource: https://data.economie.gouv.fr/api/records/1.0/search/?dataset=prix-carburants-fichier-instantane-test-ods-copie&q=&sort=-prix_valeur&facet=id&facet=adresse&facet=ville&facet=prix_maj&facet=prix_nom&facet=com_arm_name&facet=epci_name&facet=dep_name&facet=reg_name&refine.prix_nom=Gazole&geofilter.distance=XXX%2CYYY%2C5000
json_attributes_path: "$.['records'][0].fields"
json_attributes:
- adresse
- com_name
- dep_name
- geom
value_template: "{{ value_json['records'][0].fields.prix_valeur }}"
unit_of_measurement: "€"
Expected situation:
I would like to be able to do something a bit like this (see the end of the resource URL)
- platform: rest
name: Cheapest Diesel around me
unique_id: cheapest_diesel_around_me
resource: https://data.economie.gouv.fr/api/records/1.0/search/?dataset=prix-carburants-fichier-instantane-test-ods-copie&q=&sort=-prix_valeur&facet=id&facet=adresse&facet=ville&facet=prix_maj&facet=prix_nom&facet=com_arm_name&facet=epci_name&facet=dep_name&facet=reg_name&refine.prix_nom=Gazole&geofilter.distance=<MY_VARIABLE>
json_attributes_path: "$.['records'][0].fields"
json_attributes:
- adresse
- com_name
- dep_name
- geom
value_template: "{{ value_json['records'][0].fields.prix_valeur }}"
unit_of_measurement: "€"
In the above, I am adding a variable as the value of the query parameter “geofilter.distance” so that I can adjust the value in Home Assistant, and have the sensor respond accordingly.
For example, I can easily adjust the radius (in meters) around which I am looking the cheapest gasoline station
XXX%2CYYY%2C5000 => XXX%2CYYY%2C10000
That would be really grateful of the REST integration properly supports variables like this.
Thanks
