• circuitry couplable to each of a plurality of motorized window treatments, each of the plurality of motorized window treatments disposed proximate one of a plurality of windows on a single façade of a building;
• circuitry couplable to each of a plurality of daylight sensors, each of the plurality of daylight sensors associated with a respective one of the plurality of window treatments, each of the two or more daylight sensors to provide an output signal indicative of a level of light incident on the window proximate a respective one of the plurality of motorized window treatments;
• and
• motorized window treatment control circuitry to:
• receive an output signal from each respective one of the plurality of daylight sensors, each output signal indicative of the level of light incident on the window proximate the motorized window treatment associated with the respective daylight sensor;
• form a plurality of daylight sensor subgroups, each of the plurality of daylight sensor subgroups having a different defined light level range and including two or more daylight sensors, each of the two or more daylight sensors having an output signal indicative of a light level within the defined light level range of the respective daylight sensor subgroup;
• and
• for each of the plurality of daylight sensor subgroups:
• determine a brightness value representative of the level of light incident on the two or more daylight sensors included in the respective daylight sensor subgroup;
