Sending a character string ?

Is it possible to send a character string (non-numeric) in a field? Of course, no numerical analysis would be possible and it would not be possible to plot the data in a graphic, but I would need that as sort of a log file for special events.

You can send strings. As you said, the automatic field plots wont work but string data is accepted. To read the data in MATLAB, use thingSpeakRead(...'outputformat','timetable') to get the string data. When you read with the REST API, no modification is required for the string data.

Write the data to the status field (...&status=myStatus... ), and then set 'show status" in your channel settings.
