Overview

  • The aim of this lesson is to learn how to retrieve weather data from the Bureau of Meteorology (BOM) using an API (Application Programming Interface).
  • An API is simply a URL that will automatically request data from a server.
  • In this example we will extract rain data from the daily weather forecast.
  • The daily weather forecast includes rain forecast data up to 7 days in advance.
  • We will use this data for our smart rainwater tank.
  • Smart rainwater tanks need to know rain events up to 7 days in advance so that they can discharge tank water before a storm arrives.

Learning Objectives

  • Learn how to use the Developer tools in a Web Browser to find an API
  • Learn how to use an API with HTTP Request node in Node-Red
  • Learn how to extract data from a larger data sets using the function node
  • Learn how to prepare data for a chart node
