By now, you've probably heard about MQTT. Since its creation in the late '90s, it's become the most popular protocol for IoT applications, repeatedly touted by organizations like the Eclipse Foundation, big players in cloud services like Microsoft and Amazon Web Services, and influential automation vendors like Inductive Automation.

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!

A manager usually doesn’t approve a major expenditure without a detailed accounting of where the money is spent. So why isn’t energy typically accounted for in the same way?
On the OT (Operational Technology) side of manufacturing, process, and other industrial facilities, energy is often a fixed, overhead cost. The plant manager or machine operator is responsible for performance metrics like throughput and quality, while the energy bill is paid by someone in the accounting department. The implication of this lack of energy visibility is often operational costs that are higher than necessary.

Ready to write a control program for your groov EPIC, but not sure how to get started? With three options to write your control program–PAC Control, the easy-to-learn flowchart language, the Linux-based Secure Shell (SSH) to run your custom program, and CODESYS, an IEC-61131-3 compliant language–which do you choose?

Hopefully, you caught the recent blog post that announced our new 3-phase groov Power Monitoring module (GRV-IVAPM-3). In this next blog post, we’ll take a closer look at this module to help you get up to speed on how to install and configure it for your power monitoring applications.

Opto 22 engineers have addressed the Log4Shell/Log4j vulnerability recently reported in news media this week. Firmware and software updates for affected products are now available. Opto 22 urges you to apply these updates immediately, regardless of whether you're using groov View.
The Log4j vulnerability affects all products running groov View software, including:
Please see this Opto KB Article (KB90085) for more details.
Please note that the following Opto 22 products are NOT affected:

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.
