I am trying to find a way to display the last meaningful value of a Pi tag (sample of a line), but I cant. What I am trying to do pretty much is to update my spreadsheet with today's date and the sheet to look back in the last meaning full value and display it excluding all the others. Can you please help? if I try to get all the data it shows "I/O Time" and at some point one value.
Many thanks for your help
