If we want to use information about the weather, sunrise or sunset in the system, we can use an external website for this purpose, e.g. https://openweathermap.org/.

According to the example on: https://openweathermap.org/current, 

the API query looks like as following:
API call: api.openweathermap.org/data/2.5/weather?q={city name}&appid={your api key}.

Below is presented how we can easily obtain this information:

• Create the HttpRequest periphery object:
   
• The following parameters should be set in the HttpRequest object:
  Where:
  Host: api.openweathermap.org
  Path: /data/2.5/weather
  QueryStringParams: q=Krakow&appid={your api key}
  
  Warning! The api key is obtained after creating an account at: https://home.openweathermap.org/users/sign_up
  
  
• The next step is to create user features of the number type:
  
• Then prepare the script:
  

  local resp = GATE_HTTP->open_weather_map->ResponseBody
  
  GATE_HTTP-> owm_lon = resp.coord.lon
  GATE_HTTP-> owm_lat = resp.coord.lat
  GATE_HTTP-> owm_weather_main = resp.weather[1].main
  GATE_HTTP-> owm_weather_desc = resp.weather[1].description
  GATE_HTTP-> owm_weather_base = resp.base
  GATE_HTTP-> owm_temp = resp.main.temp
  GATE_HTTP-> owm_temp_min = resp.main.temp_min
  GATE_HTTP-> owm_temp_max = resp.main.temp_max
  GATE_HTTP-> owm_pressure = resp.main.pressure
  GATE_HTTP-> owm_humidity = resp.main.humidity
  GATE_HTTP-> owm_visibility = resp.visibility
  GATE_HTTP-> owm_wind_speed = resp.wind.speed
  GATE_HTTP-> owm_wind_deg = resp.wind.deg
  GATE_HTTP-> owm_cloud_all = resp.clouds.all
  GATE_HTTP-> owm_country= resp.sys.country
  GATE_HTTP-> owm_sunrise = resp.sys.sunrise
  GATE_HTTP-> owm_sunset= resp.sys.sunset
  GATE_HTTP-> owm_timezone = resp.timezone
  GATE_HTTP-> owm_city = resp.name

  
  
• Assign the script to the OnResponse event in the HttpRequest periphery object:
  
  
• Then, the configuration should be sent to the CLU.
• After the configuration has been successfully sent, the SendRequest method should be called in the Control tab of the HttpRequest periphery object:
  
  
• After calling the method, the StatusCode feature should receive the value 200.
  
  
• User features values should receive appropriate values:
  
• To verify received information, it is possible to paste query to an internet browser and compare:
  
  
• The obtained data can be displayed in the mobile application and Smart Panel or use to create logic in the system.
