Download the updated MQTT technical guide (form 2350) to better understand using MQTT in groov EPIC and groov RIO.

If you've been a long-time OptoBlog subscriber or have used Opto 22 groov products, you've heard about the MQTT technology included in groov EPIC and RIO.  We've even created a section of the website dedicated to MQTT Resources like white papers, videos, and technical articles to give you a better understanding of this popular protocol.

One of the resources worth referencing is the Getting Started with MQTT in groov Products technical guide.  This comprehensive, structured user's guide helps you make an educated decision about which of the MQTT clients and options in groov products are best suited for your application. The guide explains the features, differences, and configuration procedures of each. Plus, you'll find some additional resources to help you build out your MQTT network or make a pitch for using MQTT.

Just recently, the guide has been updated to include changes made to the groov Manage menu. You'll notice configuration for both MQTT and OPC UA have been moved to a new menu button called "Data Service." The guide features illustrations and more details about these recent updates.

Catch up with a successful Plugfest in episode 10 of IntegrateLive!

What happens when you take hardware from Opto 22, SignalFire, Wireless Telemetry, and Phoenix Contact, along with software from Software Toolbox 's DataHub using both legacy PLC data and new greenfield data, and then bring MQTT Sparkplug into the mix to publish the data?

See for yourself as the IntegrateLive team, along with representatives from all these companies, make magic happen in this special edition Plugfest, made possible by the Eclipse Foundation and its Sparkplug Working Group.

Watch the recording to see how Cirrus Link Solutions, Inductive Automation, HiveMQ, Canary, and Flow Software also all had important roles in this ambitious MQTT Sparkplug build-out.

Join Cirrus Link Solutions and Opto 22 in Houston for a joint exhibit showcasing solutions for the oil and gas industry.

Looking at automation to meet your challenges with wellsite applications? Come to the upcoming Onshore Wellsite Automation event. We'll be there with Opto Technology Partner, Cirrus Link Solutions. 

Join us in Houston January 31 - February 1, where you'll see live product demos using MQTT on groov EPIC and groov RIO. You'll also learn best practices to achieve data mobility and the security required for today’s industrial cyber environment. 

See how system integrators in water/wastewater, natural gas production, and manufacturing leveraged MQTT and industrial edge devices to securely access and use key data.

If your goal is to get useful data from field devices and legacy systems, you’ve probably found that putting together an IIoT system is complicated, requiring many OT and IT devices, software, and protocols.

But these 3 real-world case studies show how two tools—the MQTT communications protocol and industrial edge devices—can simplify your IIoT project. 

Join us for another episode of IntegrateLive! dedicated to the MQTT Sparkplug specification.

Kick off the new year with a discussion led by the Sparkplug Working Group in the first IntegrateLive! event of 2023. With the recent release of Sparkplug 3.0, this special edition of IntegrateLive! will offer more insight and in-depth conversation on the new spec and how to choose your next Sparkplug-compliant solution.

Opto 22 is a proud member of this Eclipse Foundation group, which is dedicated to educating others on the benefits of MQTT and Sparkplug. The Sparkplug Working Group directly impacts the future success of hundreds of thousands of automation projects by enabling "plug and play" IIoT! 

New categories and reorganization of topics are just some of the reasons to visit the OptoForums.

Whether you're new to using Opto 22 products or a long-time user, you can benefit from checking out the OptoForums. It's where engineering minds meet to post questions, answer fellow forum user questions, recommend solutions or even provide code samples—all related to Opto 22 hardware and software.

Moderated by Opto 22's Ben Orchard and Terry Orchard, the Forums are another great resource to keep bookmarked for troubleshooting or application advice.

And the Forums recently went through some reorganization, with more topics and categories added to help you find your answers more quickly and efficiently. Take a look at what's new.

Come along on a houseboat trip to Lake Powell to see what's possible when you bring a groov RIO and SpaceX Starlink on vacation.

Opto 22's VP of Product Strategy, Benson Hougland, has often described Lake Powell (which stretches from southern Utah to northern Arizona) as one of his favorite vacation destinations. A houseboat vacation has become a family tradition that always took him "off the grid" for a week. This year was a different story.

With a groov RIO edge I/O module outfitted with some temperature sensors, and the convenience of a Space X Starlink satellite internet system on board, this year's trip made for some memorable moments in remote automation.

Following the recent groov EPIC 3.4 firmware update, groov RIO offers similar updates in its 3.4 release.

Here are some exciting additions in the latest groov RIO 3.4 package. All these new features are available in all groov RIO models: MM1, MM2 and RIO EMU.

The biggest news is the embedded OPC UA server. This is a first of its kind: a fully functioning OPC UA server option for a remote, Ethernet-based input/output module.

Opto 22 Tech Partner HiveMQ hosts an all-new webinar using MQTT technology with groov RIO.

Need to push IIoT data instantly and bi-directionally between your device and your enterprise systems? 

HiveMQ shows you how to efficiently move data across networks and cloud platforms with their MQTT broker and client-based messaging platform. Key features: high availability, security, real-time troubleshooting, and management tools. 

These are just a few of the reasons Opto 22 has partnered with HiveMQ for both groov EPIC and groov RIO products.

Major release adds embedded OPC UA server, expanded MQTT/Sparkplug options, SNMP, Scratch Pad data access, and more

Everyone here at Opto is very excited to announce that the latest EPIC firmware update is now live.

Just as you update the OS on your phone to get the latest improvements in security, stability and performance, the OS on your groov EPIC is no different. It is after all, a quad core Linux computer, so updates are very important for the exact same reasons: security, stability, and performance.

And often these updates come with some cool new features. With this release, you'll find several.
