all was going well with thingspeak, untill just recently when I wanted to use the last entry. the problem is because my matlab skills suck I am parsing 4 lots of data every 20 min so it updates my data one at a time. all ok but now I want the last data for gauges it shows null and then whatever it updated last.

is there any way to get the last good data reading ? instead of 



all i get is 87 for my gauge :/ any ideas that doesnt involve breaking my working matlab install?

Mr. TheRipper,

Do you want just the last entry in a field?  There is a specific REST call for last entry in a field.  As long as there is a number in the last 8000 entries, the read last field entry should work for you.

I assume you are presently reading the last entry in the feed, not the field, which is why you get all the null values.

The syntax is similar. For example,

If that's not what you were looking for, please let me know.
