Flexible, low-cost water monitoring with edge I/O

Posted by Janice Colmer on Feb 11, 2022 7:30:00 AM

Remote I/O over MQTT helps Rust Automation deploy affordable remote monitoring in a challenging environment.

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!

New REST API Node-RED Video

Posted by Terry Orchard on Jan 26, 2022 7:11:10 AM

New video just added to the Node-RED developer playlist covers a simple API flow using daily weather data as an example.

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.

The Art of the Possible: Collaborative data management

Posted by Josh Eastburn on Jan 18, 2022 3:12:56 PM

Get everyone on the same page with data tools that help you distinguish the signal from the noise. Tor Eriksen of Clarify explains how.

Clarify helps people turn data into good decisions

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!
