I am uploading data to a ThingSpeak channel from a Arduino MKR1010. When I run my Matlab Analysis script from the Apps window it runs correctly reads and displays output and generates an Alert email. I have set a React condition to a numeric field being uploaded. When this field data meets the React condition the Last Ran time shows that the React file did run but it does not appear to run the Matlab Analysis script or if it does the script does not generate a Alert email.

Hi Team, I have a channel with data in field1 to field6. Now I want to use these data points to calculate the values for field 7. But I can't write the data with the exact same timestamp as the values of field1 to field6. I know, I could write the calculated data into a new channel, but I think this is a rather inelegant solution. One workaround is to add one second to the timestamps. But again, I would prefer a cleaner solution. Is there a way to do this properly?
