@afelix , @TotallyInformation e @ kuema thanks for the replies!
I am very grateful for the clarification that you were able to give me about NodeRed and sorry if for some reason my question got very confused or I mixed things up at some point, but with the content you gave me I was able to understand the general idea of how you can help me all this potential of NodeRed and also motivated me to "devour " 
the documentation to start some tests.
Thank you very much, have a great day!
