With the growth of the industrial internet of things (IIoT) and edge devices, are you looking for better ways to access your data? Opto 22's new groov EPIC system includes the Node-RED environment with the MQTT transport protocol for efficient publish/subscribe data communications. Watch this new video to see how it works!
The video covers:
- How the MQTT model works
- What is an MQTT broker
- Advantages and disadvantages of MQTT
- How to use MQTT to turn on a digital output
- MQTT Node-RED Node
A new video was also just added to our popular Node-RED video series. If you've watched the Intro to Node-RED videos, you'll want to check out the latest "Top 5 Node-RED Core Nodes".
Opto 22's Terry Orchard will show you how to set up a flow using all 5 of these core nodes:
- Function node
- Report by Exception node
- Switch node
- Email Output node
- Change node
Open-source Node-RED is included in the groov Edge Appliance. With Node-RED built in, you can quickly build simple logic flows to communicate with software, online services, and devices, and move data where you need it.
