Abstract

A method for calibrating an automated window covering includes electromechanically actuating a window covering and measuring electrical current required to actuate the window covering. The method further measures movement of the window covering, where such movement includes one or more of a change in position and velocity of the window covering. The method estimates a size (e.g., height, width, area, etc.) of the window covering and/or an amount of force required to actuate the window covering based on the measured electrical current and movement. A corresponding apparatus is also disclosed herein.
