1. A motorized window treatment system, comprising:
a plurality of motorized window treatments, each disposed proximate a window on a single façade of a building;
a plurality of daylight sensors, each of the plurality of daylight sensors associated with a respective one of the plurality of motorized window treatments, each of the plurality of 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;
motorized window treatment control circuitry coupled to each of the plurality of motorized window treatments and coupled to each of the plurality of daylight sensors, the motorized window treatment control circuitry to:
receive, from each of the plurality of daylight sensors, the output signal indicative of a level of light incident on the window proximate the respective motorized window treatment;
dynamically form a plurality of daylight sensor subgroups responsive to changes in the respective sensor reading received from each daylight sensor included in the plurality of daylight sensors, 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 output signals 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;
determine whether the brightness value is at or above a defined light override mode threshold value; and
determine whether the brightness value is at or below a defined dark override mode threshold value.
