New video just added to the Node-RED developer playlist covers a simple API flow using daily weather data as an example.

Node-RED is an extremely powerful tool that we’ve featured many times on this blog and our YouTube channel, and 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.

If you follow this blog closely you'll have seen the news that the groov family has had a recent firmware release—version 3.3.1 for groov EPIC and 3.3.0 for groov RIO. 

This release brings a lot of great features that you can see in the OptoBlog posts linked above, but here I'd like to talk a bit more about the additional features added for Node-RED, specifically for the Node-RED Dashboard.

The OpenJS Foundation and nodered.org have officially released Node-RED version 1.0!

Since the previous major Node-RED version v0.20, there have been big changes and improvements to both the visual editor on the surface and the runtime under the hood. These improvements are what truly make this a full version 1.0 update, and not just an iterative v0.21. This blog post will cover what has been updated or changed at a high level, and discuss the impact on users of Node-RED running on groov EPIC.

As you might have read in previous blog posts, groov EPIC runs a Linux-based operating system that supports a variety of programming and operating options, including optional secure shell (SSH) access. SSH provides root access to the tools, software, and files on the groov EPIC system.

But how does SSH access work, what is it capable of, and is it right for you? In this post I’ll go into a bit more depth about secure shell and the Linux operating system (OS) on groov EPIC and provide answers to these questions.

Have you ever been stuck on a coding problem? Unsure of which tool to use for an application? Or if you have the functionality you need to get the job done? Maybe you’ve just got a new system and need a map to help you learn the new features and functionality.
