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.

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!

Get a recap of the most searched topics and popular OptoForum posts of the year.

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.

In step with our recent groov EPIC 3.3 firmware release comes our groov RIO 3.3 firmware update.

Ready to hear about new features included in our popular groov RIO edge I/O module? The recently released groov RIO firmware update 3.3 is now available. Here are some reasons you'll want to update!

Several highly requested features have been added to the latest firmware update for groov EPIC PR1 and PR2.

Even with the Covid pandemic lingering on, our mostly remote team of software engineers at Opto 22 have been hard at work. As a result, we have a groov EPIC firmware update that addresses a bunch of requested features, and like any software update, some bug fixes as well.

Simply known as version 3.3.1, you can freely download and take advantage of these improvements right away.

Let's take a look at what's new...

Opto 22's YouTube channel is growing with more videos and subscribers.

What started several years ago as a platform to host a few Opto 22 product videos has now reached a new milestone. The Opto 22 YouTube channel recently reached 2 million views and is closing in on 20,000 subscribers.

Whether you're new to the industrial automation industry, or are looking for specific developer tips on using MQTT or Node-RED, the OptoVideo channel is your one stop for all things automation and digital transformation.

Sharpen your drawing tools. It's time to go to work.

Visualization for industrial automation is bigger than it’s ever been, and it’s not just about control anymore. As it becomes increasingly important to turn data into information efficiently and ubiquitously, visualization platforms deal with more data types, presentation formats, and a broader range of users and use cases. As always, Opto 22 gives you many tools so you can choose what fits your project best. Let’s take a look at some of those options.

A new video has just been added to the Node-RED developer series that takes a closer look at MySQL database nodes.

Have you been watching our Node-RED video series? If you're an NR user or want to become one, you don't want to miss out on Terry Orchard's tutorials. His latest video will unlock your honest-to-goodness Node-RED superpowers with step-by-step instructions on moving user inputs and device signal data into and out of a MySQL database.

Learn more about Time Proportional Output (TPO) and how you can use it on the groov RIO edge I/O module.

Do you need to control a digital output from an analog input?

If so, perhaps TPO is the solution you seek. Did you know that a groov RIO has 8 built-in TPO controllers and each can be configured for a different time period? We just need a little setup assistance in the form of a Node-RED flow. Before we get into that, let's talk more about just what TPO is.
