I am trying to put some modbus values into a csv file but haven't been able to do this so far.
Is there anyone who can help me how to do this?
My flow looks like this I read 6 values from modbus and I am trying to put al of these values into one csv file.
Is the problem that you need to merge the data from the different sources into one message in order to build the CSV data? If so then there have been several threads here in the last two days on exactly that problem, and there is an example of how to do it in the node red cookbook site (look for joining streams).
