The first thing to do is to use debug nodes to work out where the problem is occurring. Once you have done that, if you need further help, then post what a debug node showing what is going into the node that is not working shows and also tell us what is coming out and what should come out. If it is a function node then post the contents of the node (use the </> button when pasting it here).
If it is a function node that is failing then first look at the node red docs page Writing Functions which has help on debugging functions.
Do you mean the output of the function node is not correct? If so please read my post again. First go and read the document I linked to and attempt to debug the function node yourself. If you still cannot get it working then show us what is going into the function node, what is coming out of the function node and the code of the function node.
Can you show us again what is going into the file node please. Make it a bit bigger on the screen if possible, it was not clear on the previous one. Just what is going into the file node.
Thanks for your timely help
I have done everything as per your instruction. I am able to read many parameters in single go. But I am stuck with CSV file . I changed the flow and did some modifications too, but same error exists again.
Other part of flow for energy is running successfully.
That makes a bit more sense now, with the csv node before the file. You had the csv file after the file node before which is why I could not understand how csv data was getting into the file. I rather suspect that the debug output you showed the first time was with this flow.
So now we have to see why the csv node is not doing what you want. You need to show us how you have configured the csv node. Remember we are not telepathic so it is not possible to know these things unless you show us.
Actually, I don't think that is the problem. Having said that we are not telepathic I am now going to predict that you have provided a list of headings in the csv node (Timestamp, HV1_0, ...). The node uses those to determine which properties of the object you pass in to put into the csv data. Unfortunately none of the properties in the header list are present in the data you are passing in (except the timestamp), so the columns are all empty.
You have gone over the top now in providing data
Now we know that it is the csv node that is not behaving as you expect then that is what we need.
Did you see my reply a few minutes ago, explaining what the problem is?
Even i tried Posted my program, Notified as program exceeded the character limit.Unable to post it
You have given solution for it. sorry i didnt view it, i will check and update you
Yes Colin. i have done a same set of data with different parameters , the difference is i need that data to be sent to Cloud bd via CSV using q-gate. with your guidance i have achieved my output.
Working on this second part. got struck up with CSV file. Tried many times before raising the issue. But i couldnt solve it.
Im Seeking Help with you all. so that any1 can guide me in getting output in flow
Appreciate , your effort in notifying the issue
thank you !
As Colin predicted... In the debug you can see HAV1_0 etc. And yet in the CSV node you ask for HV1_0 etc. Which doesn't exist, so you get blanks. It is important they are the same..
