  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 whose 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 in configuration.yaml:
      ```yaml
      shell_command:
        curl_get: 'curl -X GET {{ url }}'
      ```
