It’s important to be able to manage Node-RED projects for recovery, version control, copying flows to other devices, and sharing code. There are several ways to do this, but what should you be aware of and what are the best practices for doing this on a *groov* device?  [Read More](https://blog.opto22.com/optoblog/node-red-configuration-nodes-and-project-management) 2 Comments [Click here to read/write comments](https://blog.opto22.com/optoblog/node-red-configuration-nodes-and-project-management#comments-listing) Topics: [Node-RED](https://blog.opto22.com/optoblog/topic/node-red), [MQTT](https://blog.opto22.com/optoblog/topic/mqtt), [groov EPIC](https://blog.opto22.com/optoblog/topic/groov-epic), [groov RIO](https://blog.opto22.com/optoblog/topic/groov-rio) ## [groov RIO Ignition Exchange Project Spotlight](https://blog.opto22.com/optoblog/groov-rio-ignition-exchange-project-spotlight) Posted by [Terry Orchard](https://blog.opto22.com/optoblog/author/terry-orchard) on Aug 30, 2022, 8:00:00 AM - [Tweet](https://twitter.com/share) [![](https://blog.opto22.com/hubfs/MartinCSIRealTimeData.jpg)](https://blog.opto22.com/optoblog/groov-rio-ignition-exchange-project-spotlight) ### See how to quickly read *groov* RIO data into the Ignition Exchange tag database With software-configurable I/O, like that on the [*groov* RIO](https://www.opto22.com/products/groov-rio) MM1 and MM2, it’s easier than ever to instrument all your devices for control and reading back real-world data. To help you take the next step of getting that data somewhere meaningful, this post will summarize a new Ignition Exchange project for reading data from one or more *groov* RIO modules into your Ignition tag database. Posted by [MartinCSI](https://www.opto22.com/community/opto-partners/martin-control-systems), an IoT-certified OptoPartner, this project makes it trivial to dynamically get tag data into the Ignition tag database, display it on Vision pages, and link it to other projects and providers where you can then do whatever you need.

Node-RED is an extremely powerful tool that we’ve featured many times on this blog and our [YouTube channel](https://www.youtube.com/c/OptoVideo), 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.

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.

SSH provides root access to the tools, software, and files on the [*groov* EPIC system](https://www.opto22.com/products/groov-epic-system).
