ESP8266 Parsing Library for OpenWeatherMap Site

About

Suppose you are creating a project that requires weather forecast information. For instance it can be some kind of a weather station or smart clock or something else. This library can help you complete your job supplying the interface to OpenWeatherMap data. At the moment the library supports three data forecast request types:

• current condition

• 5 day forecast (hours period)

• 16 day forecast

The library requires any version of the ESP8266 controller. To run the library you need register on openweathermap.org and get your authentication key.

Example

The library has one simple example that prints the forecasts on the serial port as follows:
