1. A load control system for controlling an amount of power delivered to a plurality of lighting loads, the plurality of lighting loads including a first lighting load and a second lighting load, the load control system comprising:a load control device configured to control the amount of power provided to the first lighting load; and
a master device configured to:
determine an on/off state of the plurality of lighting loads;
store the on/off state of the plurality of lighting loads;
receive an indication to change the on/off state of at least one of the first or second lighting loads;
determine, from the previously stored on/off state of the plurality of lighting loads, that the on/off state of the first lighting load and the second lighting load are out of synchronization; and
transmit, to the load control device, a command that is configured to synchronize the on/off state of the first lighting load and the second lighting load.
