[SOLVED] ISpindel calibratio

Hi,

I have calibrated my ispindel and have the formula related to its tilt and would like to create a widget for the dashboard. The guide I am following says I need to add a derived variable but I only have the option to add Raw or synthetic.

Is the derived function a premium account feature and is there a way around this?
Thanks in advance.
Harry
