How to access data no matter where your Node-RED server is running

The Node-RED how-to video series continues with some tips on using certificates. Recent videos in the series covered why you should run Node-RED on groov devices, and how to install and configure Opto 22 Node-RED packages for PAC Control, groov I/O and groov View.
Now Terry Orchard is back at the demo desk to show you how to use both self-signed and Certificate Authority certificates to help move data between groov RIO and EPIC, no matter where your Node-RED server is running.
