Glad you got it working. Indeed, NodeRed is a game changer in the industrial field. I have many RPis running at work doing a multitude of different things. Scanning and verifying parts to BOM from SQL, logging PLC values, charting, comm gateway for a thermal imager to a PLC, etc.
I wouldn’t say I am good with NodeRed, but Googling....that’s my skill. 
lol
