Next up in the Node-RED videos series is a tutorial about using Swagger to help set up API calls.

In under 20 minutes, this new developer video from Terry Orchard will take you through all the steps you need to get a solid understanding of using Swagger UI pages to create API calls you can bring into Node-RED. Using them together, you can control all sorts of APIs from your groov device, both getting and posting data, using simple Node-RED.

Next up in the Node-RED developer video series, this tutorial makes it easy to create your own HMI or dashboard.

When we first introduced the Node-RED developer video series a few months ago, we started off with how to "Set up groov I/O nodes." Once you've installed and configured them, it's time to do something interesting with your data.

This new video does just that. Next up in the Node-RED video series is the Basic Node-RED Dashboard UI Tutorial.

Waiting to dip your toe into the MQTT pool? Jump into this new user guide, and get started with MQTT and Sparkplug B on your Opto 22 groov products.

If you're already an OptoBlog subscriber, chances are you've become familiar with the MQTT protocol. We understand it can be a little daunting to take the leap into a new approach, though, so we expanded and revised our popular four-part MQTT blog series to create a complete guidebook for lightning fast MQTT publication on Opto 22's groov EPIC and RIO.

Topics: IIoT, Node-RED, MQTT, Ignition Edge, groov EPIC, groov Manage, groov RIO

Get an up-to-date overview of the groov EPIC system in only two minutes with this new video.

Since its release in 2018, groov EPIC has continued to evolve, with new features that make it an even stronger choice for your IIoT and automation applications.

Take advantage of a new section of Opto 22's website devoted to groov RIO resources and tools.

As an OptoBlog subscriber, you've heard us talking about our latest edge I/O offering, groov RIO (GRV-R7-MM1001-10). It's I/O for the IIoT™. We've previously shared a press release, video, webinar, and a white paper resource for this exciting new product. And now there is one place to go for all your groov RIO questions...

Our MQTT series continues with a deep dive into groov EPIC’s (and now groov RIO’s) features for high-reliability MQTT networks.

At its heart, MQTT was designed for unreliable networks. Back in the ’90s, ConocoPhillips (now Phillips 66) was looking for a way to improve telemetry reporting over its low-bandwidth dial-up and costly VSAT (small satellite dish) SCADA network. IBM partnered with system integrator Arcom Control Systems (now Cirrus Link Solutions) to develop a minimalist communication protocol that could gracefully handle intermittent network outages and high latency among many distributed devices over TCP/IP.

In part 2 of our series, we look at how to set up groov Manage and Ignition Edge for publishing with Sparkplug B payloads.

MQTT is the darling of enterprise IoT because of its efficiency, simplicity, and flexibility, which makes it ideal for use in applications that communicate with resource-constrained edge-of-network devices. After being nurtured for years within IBM, and incorporated into their smart energy, health, and utilities solutions, MQTT has become the chosen messaging protocol across all the major cloud IoT platforms as well as highly scalable applications, like Facebook Messenger.

Wondering how to implement MQTT with groov EPIC? Follow along with this series, starting with basic string publishing.

Ever since ‘00, when the next year rolls around I think, “Welcome to the future!” Every year it feels much truer, and how could 2020 be any less? (UPDATE: 🤦) I’m excited about what we have planned for you this year. Among other things, we’re upping our commitment to MQTT in a big way. Stay tuned for announcements on that in the coming months.

For the moment, though, I want to address the current feature set groov EPIC offers for MQTT, the lightweight pub-sub communication protocol for IoT. With so many ways to do it—via groov Manage, Node-RED, or Ignition Edge—you may be wondering which, if any, is right for your application. In this series, I’m going to look at different scenarios where you might want to use MQTT, then show you how to get started.
