Did you know that you can install additional gadgets to the Node-RED dashboard? Terry Orchard returns to the OptoStudio to show off the features of the ui-table node. Learn how to install the table node package and configure different kinds of tables to fit your needs, complete with several examples using live, real-world data.

What if you need to snapshot a message from a very specific part of a Node-RED flow?
For those of you who've been using the Node-RED programming tool or are just getting started, Terry's latest video provides some guidance on storing data. In a Node-RED flow, each node can add to, modify, or delete data in different ways.

OptoBlog followers are most likely familiar with Terry Orchard's Node-RED video series, and he's recently added a new video to that playlist. This time, Terry's goal is to introduce you to the JSON data format, so it's easy to understand and simple to get started with.
Machine vision systems can recognize superficial aberrations in manufactured goods—like lines, spots, holes, color discrepancies, and more—that would typically require time-consuming manual inspection. California-based Intrinsics Imaging solves this problem with its Heijunka Vision analytics-as-a-service software. But when Intrinsics was approached by a customer hoping to integrate Heijunka directly into process controls, it looked to Opto 22’s groov RIO edge I/O for a way to connect the cloud to the edge.

Hopefully, you caught our two previous related blog posts on the technical details of the groov EPIC Power Module, and the recent announcement of the new groov RIO EMU.
In this blog post, I’ll focus on the unique features of the RIO EMU as a distributed power and energy monitoring device, plus so much more.

Did you watch the Fall CODESYS Tech Talk virtual event that we shared with you last October? It demonstrated how the CODESYS runtime engine works and why it's included on Opto 22's groov EPIC.
Jared Bates, from OptoPartner Rust Automation & Controls, joined us for that presentation. He discussed a current water management application that utilizes CODESYS on EPIC, groov RIO remote I/O, and MQTT for secure data communications.
Now, we've put the story of all that cutting-edge technology into a case study, so you can dig into all the details!

Node-RED is an extremely powerful tool that we’ve featured many times on this blog and our YouTube channel, 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.

Last year, Opto 22 had the opportunity to showcase some amazing partner collaborations like our webcast with HiveMQ and Canary. The open automation ecosystem continues to explode with potential, so this year we wanted to bring you even more.
Throughout 2022, we’ll explore what’s possible when you pair Opto 22 hardware with other open automation tools. This series will include some heavy-hitters you might be familiar with as well as some new names. Hopefully at least one will turn on a lightbulb for you!
Our first guest is Tor-Inge Eriksen of Clarify, a time-series visualization platform that helps users quickly turn data into information. Tor, take it away!

Let’s take a look back at 2021 through the eyes of the OptoForums. You remember last year's top 5, right?
For starters, we had almost 200 more people sign up this year over last. (Y-Axis below is the number of daily sign-ups).

If you follow this blog closely you'll have seen the news that the groov family has had a recent firmware release—version 3.3.1 for groov EPIC and 3.3.0 for groov RIO.
This release brings a lot of great features that you can see in the OptoBlog posts linked above, but here I'd like to talk a bit more about the additional features added for Node-RED, specifically for the Node-RED Dashboard.
