1. A handheld control device to control light intensity in a space, comprising:
electrical load controller control circuitry to:
determine a location of the handheld control device;
receive, from a communicatively coupled sensor, a signal that includes data representative of a measured ambient light intensity in the space;
determine a difference between the measured ambient light intensity in the space and a target light intensity;
responsive to the determination that the ambient light intensity differs from the target light intensity by greater than a defined threshold value:
adjust the ambient light intensity within the space by adjusting at least one of:
an artificial light source disposed in the space; or
a natural light control device disposed in the space.
