Usage

Two nodes that get the weather report and forecast from OpenWeatherMap.

Input Node

Fetches the current weather and forecast at a location specified by name or lat,lon every 5 minutes - and outputs a msg if something has changed.

Query node

Accepts an input to trigger fetching the current weather either from a specified location name or lat,lon or passed in on

    msg.location.city and msg.location.country
    or
    msg.location.lat and msg.location.lon

Results

Both will return

• description - a brief verbal description of the current weather for human reading.
• weather - a very short description of the current weather.
• tempc - the current gorund temperature at that location in Celcius.
• tempk - the current gorund temperature at that location in Kelvin.
• humidity - the current relative humidity at the location in percent.
• windspeed - the current wind speed at the location in Metres per second.
• winddirection - the current wind direction at the location in meteorological degrees.
• location - the name of the location from which the data was sourced.

The node also sets the following properties of msg.location.

• lat - the longitude of the location from which the data was sourced.
• lon - the latitude of the location from which the data was sourced.
• city - the city from which the data was sourced.
• country - the country from which the data was sourced.

Finally, the node sets:

• msg.time - the time at which the weather data was received by OpenWeatherMap.
• msg.data - the full JSON returned by the API. This is VERY rich...
