    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.

    Abstract: A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

    Abstract: A system includes a window treatment adjacent to a window of a room. At least one motor drive unit is associated with the window treatment, for varying the position of the window treatment. A sensor measures a light level (e.g., an outdoor light level) at the window. A controller provides signals to the motor drive unit to automatically adjust the position of the window treatment so as to control a penetration distance of sunlight into the room when the window treatment is partially opened. The controller is configured to position the window treatment in a bright override position if the measured light level is at least a bright threshold value. The controller is configured to select the bright threshold value from among at least two predetermined values. The selection depends on an angle of incidence between light rays from the sun and a surface normal of the window.
