Hi, I would like to use this sensor on a different machine but how do I reset all data output in the displayed data from previous machine?
restart node red and old values will go away
Is it possible for me to download the data? If yes, how do I download it?
You could only display the data if you had your Node-Red flow logging the data to something like a CSV file. To my knowledge there is not a way to download the data being displayed on the line graph in Node-Red, however it could be possible and I just do not know where it is stored. I would recommend googling about node-red-dashboard graph node data storage.
