blueprint:
  name: WUnderground upload
  description: >
    Upload data from Home Assistant to WUnderground.

    Config:
      The station_id and station_key variable must be fetched from WUnderground.
      The sensor_* variables are the sensors whos data will be uploaded
      The trigger_entities variable specifies the entries to trigger state changes on (this could be a list)
      The curl_command_service variable specifies the CURL-service to execute.
      The refresh_frequency variable specifies the frequency the sensors update their data
      The dewpoint temperature can be calculated based on the outdoor temperature and the outdoor humidity.
        By default, it will be calculated, to disable this set calculate_dewpt to false.

    The CURL-service must exist in Home Assistant.
    This can be configured with the following YAML
      shell_command:
        curl_get: 'curl -X GET {{ url }}'
