need to know how to retrieve local outdoor temperature in Celsius from say "openweathermap.org" or similar so that Thingspeak/MATLABThingspeak/MATLAB can use it to analyze ideal humidity?

Thank you

在 MATLAB Online 中打开

Try weather.gov and passing in decimal degrees location for your city.

natickWeather = webread('http://forecast.weather.gov/MapClick.php?lat=42.2834300&lon=-71.3495000&FcstType=json');
humidity = str2double(natickWeather.currentobservation.Relh)

True. This a United States government feed. I do not know of any one that covers the world. What locations do you need covered?

Canadian cities, for example Calgary, Alberta. If there is a service that allows access to the weather data using Thingspeak or MATLAB?

As you mught guess, I am new at this Thingspeak/Matlab application. I can get my data to display on my channels, and I would like to do some calcs based on changing barometric pressure, outdoor temperature, e.g. for weather changes and for ideal humidity, and to Email/Txt alerts.
