Wireless Load Control System

An electric load control method, comprising:

• executing, by electric load control circuitry, a timeclock schedule using internal timekeeper circuitry to control operation of each of a plurality of load devices;
• causing, by the electric load control circuitry, a communication of one or more commands to each of the plurality of load devices via a first network using a first wireless communication protocol;
• determining, by the electric load control circuitry, whether the internal timekeeper can be synchronized to an external timekeeper via a second network using a second communication protocol;
• responsive to the determination, by the electric load control circuitry, that the internal timekeeper cannot be synchronized to the external timekeeper, determining, by the electric load control circuitry, whether a temporal error of the internal timekeeper exceeds a defined temporal error threshold value;
• and
• responsive to the determination, by the electric load control circuitry, that the temporal error of the internal timekeeper exceeds a defined temporal error threshold value, ceasing, by the electric load control circuitry, execution of the timeclock schedule.

A non-transitory, machine-readable, storage device that includes instructions that, when executed by electric load control circuitry, cause the electric load control circuitry to:

• execute a timeclock schedule using internal timekeeper circuitry to control operation of each of a plurality of load devices;
• cause a communication of one or more commands to each of the plurality of load devices via a first network using a first wireless communication protocol;
• determine whether the internal timekeeper can be synchronized to an external timekeeper via a second network using a second communication protocol;
• responsive to the determination, by the electric load control circuitry, that the internal timekeeper cannot be synchronized to the external timekeeper, determine whether a temporal error of the internal timekeeper exceeds a defined temporal error threshold value;
• and
• responsive to the determination, by the electric load control circuitry, that the temporal error of the internal timekeeper exceeds a defined temporal error threshold value, cease execution of the timeclock schedule.
