1. A load control system, comprising:
a control-target device configured to control an electrical load associated with one or more of a lighting system, a heating and air conditioning (HVAC) system, or a motorized window shade system;
at least two control-source devices for sending control instructions to the control-target device to control the electrical load, wherein each control-source device has been associated with the control-target device; and
a system controller configured to:
listen for and determine that a message has been sent by at least one of the control-source devices directly to the control-target device;
determine a content of the message; and
determine to update information stored at the system controller based on the content of the message without querying the control-target device.
