Hello,
Im doing a project where I need to log temperatures into a file so that I can later make a model from it. This is my first time ever using Node Red/programming. Right now my flow produces the information I need and puts it in a .csv file, but it doesn't always put it in the right order. The correct order of things is the following picture:
This sometimes does happen, but it is inconsistent. Sometimes it shows temperature 4 first and then time and so on.
I've searched quite a bit and found something about msg.parts, though im not sure if this would help nor how it works since i know basically nothing about coding.
Im wondering if someone has a solution for my problem so that the data stays consistent. Following is a picture of my current flow:
