(Solved) REST sensor gives no result

Configuration
1

I tried to config a rest sensor to monitor the availability of a EV charging station.

In my sensors I made a REST call:

  - platform: rest
    scan_interval: 1000
    method: POST
    name: ev_charger_sensors
    resource: "https://www.oplaadpalen.nl/api/maplist/location/6b3cb1b0-4e72-11e8-b8dc-42010a840002"
    headers:
      Connection: keep-alive
      Content-Length: 0
      Accept: application/json, text/plain, */*
      Origin: https://www.oplaadpalen.nl/

      DNT: 1
    json_attributes:
      - status_code
      - status_message
      - data
      - chargingstation
      - chargingspots
    value_template: 'OK'

But the values/attributes stay empty, in the log, no errors.

when curl from home assistant commandline, I get a JSON reply:

In the end, I only want the results of the “changringspots”-topic, but now i get only an empty response.

Where do I go wrong in this?

You can simplify your configuration a lot.
The URL does not appear to work with POST, but only GET. And I don’t know why you would need to define all those headers.

sensor:
  - platform: rest
    scan_interval: 1000
    method: GET
    name: ev_charger_sensors
    resource: "https://www.oplaadpalen.nl/api/maplist/location/6b3cb1b0-4e72-11e8-b8dc-42010a840002"
    json_attributes:
      - status_code
      - status_message
      - data
      - chargingstation
      - chargingspots
    value_template: 'OK'

OMG, it was that easy…

Thank you for the response.
I copied the header info from an other existing rest call, (tha obviously needed it, I had to login).

Thank you for this easy and quick fix!
