Weather Data Receiver

The open_weather_api data receiver reads current weather data from the OpenWeather API.

Example:

If we want to receive weather information, our configuration will look like:

{
  "data_receiver": [
    {
      "data_receiver_name": "weather_receiver0",
      "protocol": "open_weather_api",
      "connections": [
        {
          "latitude": 42,
          "longitude": -31,
          "appid": "app_id_goes_here"
        }
      ],
      "streams": [
        {
          "asset": "Weather",
          "stream_type": "climate"
        }
      ]
    }
  ]
}

Configuration:

Required and optional properties that can be configured for an OPC UA receiver:

• data_receiver_name: Unique name of the data receiver. This name will be used to track the progress state of the data stream.

• protocol: Protocol to be used. Should be set to open_weather_api.

• connections: How to connect to the weather API. A connection has the following configurable settings:

  • latitude: Latitude of the location to get the weather for.

  • longitude: Longitude of the location to get the weather for.

  • appid: Authentication token given by Open Weather – look for it in your OpenWeather account page: https://home.openweathermap.org/api_keys

• streams: List of data streams. Each input stream has the following configurable settings:

  • asset: Asset identifier.

  • stream_type: Type of data stream.

• poll_interval: The number of seconds to wait between attempts to fetch new data from the weather server.
