where do you want to display the data ?
using node red it could be displayed on the dashboard, there would be no need for nema at all to arduino ..
you could do alarms text email ect..
sk data can be read and actions taken in N.R. and sent back to arduino to do something open close relays ect.
arduino can read analog sensors and take actions in node red , display,or other actions..
so the short answer is Node-Red..
you will need a usb hub eventually..
