OptoNews: New Node-RED examples for developers

Node-RED logoIf you're using Node-RED and the nodes for SNAP PACs and groov—or if you're thinking about it but haven't startedcheck out our new Node-RED examples on developer.opto22.com

Node-RED is the open-source tool for digitally wiring together hardware devices, cloud services, databases, and more in simple logical flows.

Because you construct your flows with free, pre-built, reusable nodes, a lot of the programming is already done for you. It's an easy way to start seeing the power and usefulness of the Internet of Things. 

Node-RED nodes are available for both Opto 22 SNAP PAC programmable automation controllers and our groov mobile operator interface tool. For convenience, Node-RED is built into the GROOV-AR1 groov Box.

We have 3 examples for you:

  • Read and write to Opto 22 digital I/O modules (uses a Raspberry Pi)
  • Get a controller’s WAN IP address and write it to a tag in PAC Control
  • Use a switch node to perform an action based on the value of a property

Besides the examples, the Node-RED section on our developer site walks you through getting started with Node-RED, either on the groov Box or on your computer. And you'll find resources to learn more.

Also, be sure to check out the Node-RED category on the OptoForum. It's a friendly place to share flows and ask questions.
