Multiple location load control system

An electric load control method, comprising:

• receiving, by control circuitry, a first input indicative of a zero crossing of the AC supply from operatively coupled zero detect circuitry;
• causing, by the control circuitry, operatively coupled power supply circuitry to charge using an alternating current (AC) supply for a first portion of a half cycle of the AC supply responsive to receipt of the first input;
• receiving, by the control circuitry, a user input indicative of a first target electric load output parameter value for an electric load device operatively coupled to a controllably conductive device disposed in a remote electric load controller;
• generating, by the control circuitry, a first message that includes data representative of the first target electric load output parameter value responsive to receipt of the user input;
• providing, by the control circuitry, a buffer period for a second portion of the half cycle of the AC supply after passage of the first portion of the half cycle of the AC supply;
• and
• causing, by the control circuitry, a transmission of the generated first message during a third portion of the half cycle of the AC supply after passage of the second portion of the half cycle of the AC supply via the AD communication interface circuitry.

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

• receive a first input indicative of a zero crossing of the AC supply from operatively coupled zero detect circuitry;
• cause operatively coupled power supply circuitry to charge using an alternating current (AC) supply for a first portion of a half cycle of the AC supply responsive to receipt of the first input;
• receive a user input indicative of a first target electric load output parameter value for an electric load device operatively coupled to an controllably conductive device disposed in a remote electric load controller;
• generate a first message that includes data representative of the first target electric load output parameter value responsive to receipt of the user input;
• provide a buffer period for a second portion of the half cycle of the AC supply after passage of the first portion of the half cycle of the AC supply;
• and
• cause a transmission of the generated first message during a third portion of the half cycle of the AC supply after passage of the second portion of the half cycle of the AC supply via the AD communication interface circuitry.
