      For example, read a frequency value every minute for one hour (and add them) and then calculate the mean value (value divided by 60) and then plotting this result, thus one result per hour.


      Tnx Sven

      Hi Sven, ... There is no direct function to average those frequency readings. But you could implement a kind of integrate-and-dump filter using the

        Hi Sven,

        you asked:

        There is no direct function to average those frequency readings. But you could implement a kind of 'integrate-and-dump' filter using the conditional actions.

        Understand that abt conditional actions . Is this possible: Export a frequency value (*.txt) to Excel and do the mathematics in Excel ? /Sven

            Of course. Use a variable to hold the most recent output of the integrate-and-dump filter.
            You can either use the file commands to directly write the results into a text file (whenever the timer in the conditional actions ran off, or similar), or add the name of that variable in the 'file export' table. In fact you can write (export) anything you like this way.
            Again, it's in the manual:
