REST API command/platform fails on POST to external URL (solcast)

[safepay (Richard Mann)]

Hey Tom,

I don’t use the template sensor data for the graph. I use the Rest sensor value. This was my mod from the original (and brilliant!!) idea.

@safepay

sensor:
  - platform: rest
    name: "Solcast Forecast Data"
    json_attributes:
      - forecasts
    resource: https://api.solcast.com.au/rooftop_sites/SOLCAST_RESOURCE_ID/forecasts?format=json&api_key=SOLCAST_API_KEY&hours=72
    method: GET
    value_template: "{{ value_json.forecasts[0].pv_estimate|round(2) }}"
    unit_of_measurement: "kW"
    device_class: power
    scan_interval: 00:30
    force_update: true

Here is the raw sensor data from today:

And the corresponding graph:

Doesn’t give me any problems.

Worth a try.
