Hello,
I am trying to learn from the weather data example but I can't get it to work: Analyzing Weather Data from an Arduino-based weather station
I get this as an error:
'downsample' is used in Automatically Tune Filter to Track Maneuvering Targets.
Is downsample included with the ThingSpeak Visualization tool?
Thanks

No — downsample is not part of the ThingSpeak Visualization tool. It's a MATLAB function, and ThingSpeak supports MATLAB code, but it depends on what toolboxes are available in your license.

In particular the Mathworks downsample() function is part of the Signal Processing Toolbox
