Скачать или смотреть How to use APIs with Node-RED: OpenWeatherMap Example

One very common use of Node-RED is to use application programming interfaces or “APIs” to move data between devices and/or services that would otherwise be totally disconnected.

To help you get started using APIs with Node-RED if you’re unfamiliar with these tools, we’ve just made a new video about how to build a simple API flow using an example web service for daily weather data.

This data is used to do some basic control on a groov RIO (although the steps are the same on any device running Node-RED, including groov EPIC). Watch the full video tutorial.
