[Tweet](https://twitter.com/share) [![Node-RED logo](https://blog.opto22.com/hs-fs/hubfs/social-suggested-images/node-red-cropped-270x193-1-3.jpg?width=160&name=node-red-cropped-270x193-1-3.jpg "Node-RED logo")](http://forums.opto22.com/c/node-red)Are you wiring together devices and software using Node-RED? If you're even thinking about it, we've got a new [Node-RED OptoForum](http://forums.opto22.com/c/node-red) for you.  We announced in the last OptoNews that [Node-RED is now a built-in feature in the GROOV-AR1 *groov* Box](https://blog.opto22.com/optoblog/optonews-iiot-tool-node-red-included-in-new-groov-admin-release)! This open-source IIoT tool lets you wire together hardware devices, databases, cloud services, and APIs (application program interfaces) with simple logic flows. And it's free with your [**groov** Box](http://www.opto22.com/site/pr_details.aspx?cid=1&item=GROOV-AR1-BASE). If you already have a GROOV-AR1, just [update to *groov* Admin 45](http://www.opto22.com/site/managegroov.aspx) and you'll have Node-RED included. (Note that Node-RED is not available on the older GROOV-AT1.) [![GROOV-AR1 IIoT interface tool now includes Node-RED](https://blog.opto22.com/hs-fs/hubfs/groov_w_node-red_141x176.png?width=141&name=groov_w_node-red_141x176.png "GROOV-AR1 IIoT interface tool now includes Node-RED")](http://www.opto22.com/site/pr_details.aspx?cid=1&item=GROOV-AR1-BASE)How does Node-RED work? You build the flows using **pre-made nodes** from a hardware or software company. For example, Opto 22 provides two Node-RED nodes for accessing data in our SNAP PAC programmable automation controllers (via their RESTful API). Twitter provides a node for tweeting. Online weather services like Wunderground provide nodes to get data from their services. Mysql databases offer nodes. Hundreds of nodes are available for free. In the Node-RED web-based software, you drag and drop the nodes you need onto a workspace and then wire them together into a flow that produces the result you want. You can even add JavaScript code to a function node.  One of the cool things about Node-RED is that you can **export and import** nodes and flows to reuse and share. The Node-RED OptoForum already contains a few you can copy and import—including one of Ben's favorites, [Wunderground](http://forums.opto22.com/t/weatherundground-current-forecast-as-string/1100)—and we're sure there will be many more.  For more on Node-RED, how to use it, and how to import and export flows, see Chapter 4 in the [**groov* *Box User's Guide for GROOV-AR1](http://www.opto22.com/site/documents/doc_drilldown.aspx?aid=4441). Whether you're a Node-RED newbie or an expert, check out the new [Node-RED OptoForum](http://forums.opto22.com/c/node-red). Share your questions, expertise, and flows, and we'll all learn together.  [![See the Node-RED OptoForum](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/439485/c923e100-ae51-41c7-9a88-c9ce126014d6.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/439485/c923e100-ae51-41c7-9a88-c9ce126014d6) Topics: [groov](https://blog.opto22.com/optoblog/topic/groov), [Internet of Things](https://blog.opto22.com/optoblog/topic/internet-of-things), [IoT](https://blog.opto22.com/optoblog/topic/iot), [optonews](https://blog.opto22.com/optoblog/topic/optonews), [IIoT](https://blog.opto22.com/optoblog/topic/iiot), [Industrial Internet of Things](https://blog.opto22.com/optoblog/topic/industrial-internet-of-things), [Node-RED](https://blog.opto22.com/optoblog/topic/node-red), [OptoNews 2016-11-09](https://blog.opto22.com/optoblog/topic/optonews-2016-11-09) ### Written by [Jean Femia](https://blog.opto22.com/optoblog/author/jean-femia) Jean Femia writes about technical subjects and has focused on automation and control systems for more than 15 years.
