    Abstract: A method comprises measuring a light intensity at a window; determining if the light intensity exceeds a cloudy-day threshold; operating in a sunlight penetration limiting mode to control the motorized window treatment to control the sunlight penetration distance in the space; enabling the sunlight penetration limiting mode if the light intensity is greater than the cloudy-day threshold; and disabling the sunlight penetration limiting mode if the total lighting intensity is less than the cloudy-day threshold. The cloudy-day threshold is maintained at a constant threshold if a calculated solar elevation angle is greater than a predetermined solar elevation angle, and the cloudy-day threshold varies with time if the calculated solar elevation angle is less than the predetermined solar elevation angle. The cloudy-day threshold is a function of the calculated solar elevation angle if the calculated solar elevation angle is less than the predetermined solar elevation angle.

    Abstract: A motorized window treatment system controls a plurality of motorized window treatments to maximize daylight autonomy, while minimizing cognitive dissonance. The system may include motorized window treatments, window sensors, and a system controller. Each motorized window treatment may be operable to adjust a respective covering material to control the amount of light entering a space. Each sensor may be mounted adjacent to at least one of the motorized window treatments, and may be configured to measure an amount of daylight shining on the sensor. The system controller may receive sensor readings from the sensors and may control the motorized window treatments in response to the sensors to keep the covering materials aligned when the sensor readings are within a predetermined amount. The system controller may dynamically group and re-group the sensors into subgroups based upon the sensor readings and may control the motorized window treatments based upon the subgroups.
