Claim 0:
1. An electrical load controller comprising:
radio frequency (RF) receiver circuitry reversibly transitionable between a SLEEP state having a first duration and an AWAKE state having a second duration that is less than the first duration;
control circuitry coupled to the RF receiver circuitry, the control circuitry to, at intervals:
cause the RF receiver circuitry to reversibly transition between the SLEEP state and the AWAKE state; and
monitor for a transmitter broadcast packet received by the RF receiver circuitry while in the AWAKE state, the transmitter broadcast packet having a packet length; and
responsive to receipt of at least a portion of the transmitter broadcast packet by the RF receiver circuitry while in the AWAKE state:
cause the RF receiver circuitry to transition from the AWAKE state to a SNOOZE state having a third duration;
cause the RF receiver circuitry to transition from the SNOOZE state to the AWAKE state at the conclusion of the third duration;
maintain the RF receiver circuitry in the AWAKE state for a fourth duration to receive the complete transmitter broadcast packet; and
cause the RF receiver circuitry to transition from the AWAKE state to the SLEEP state at the conclusion of the fourth duration.
