BBC Weather Forecast component

Easily allows you to collect observed weather metrics for your area using the BBC Weather data service. Supports temperature and humidity etc. for your selected area. Also available are Wind Direction, Wind Speed and Air Pressure but please note these are not always available depending on your selected area. This component is used for data gathering from the internet.

Examples

Here is a basic example to read the three day forecast data and report the information on a graphical display.

BBCWeatherForecastDemo

The location can be set by adjusting the BBC Weather location property, see the component property tooltips for more information on how to do this.

Here is an example of a next-day weather predictor that also shows the current-day weather for a ESP32 embedded device
