I have been working on this for multiple years off and on. I have had other solutions that worked but nothing that satisficed my actual needs/wants. This project uses WEL Server which provides a service of download Excel files or there is an xml link for live data needs. Also he provides a web page for live data viewing on a SVG background. EX: http://www.welserver.com/WEL0827/
I have about 40 devices and have tried to keep it simple while I learn Node-RED but I seem to be missing the big picture. Any help greatly appreciated. attaching my flow with template of XML.
