I'm trying to determine the date of the first channel entry point. This would seem a simple exercise, but there are problems. For example, downloading the channel yield a 500 mb file which is impossible to open. Using thingspeak read with a broad range of dates yields only the ending points. If the dates are both prior to the channel start, an error is generated. What do I do?
It would be really helpful for thingspeak read to have the ability to return points by index value.
If have the file on a Linux computer, you can use the head command. If you are on Windows, you will need to open up a powershell and execute
get-content c:\path_to_file\your_file_name -totalcount 10
to get the first 10 lines.
Out of curiosity, of this 500MB of data how much of it is critical to you and how do you use it?
