1. An electric load controller, comprising:
filter circuitry;
receiver circuitry operatively coupled to the filter circuitry, the receiver circuitry reversibly transitionable between a lower power consumption sleep state and a higher power consumption active state;
controller circuitry operatively coupled to the receiver circuitry, the controller circuitry to:
cause the receiver circuitry to transition from the sleep state to the active state at each of a plurality of sleep intervals; and
responsive to the transition to the active state:
sample a filter output signal for a sampling interval; and
detect a presence of a first of a plurality of signal packets transmitted by a wireless device;
wherein each of the plurality of signal packets are separated by a packet break interval;
responsive to detecting the presence of the first signal packet:
cause the receiver circuitry to transition to the sleep state for a snooze interval;
wherein the snooze interval is less than or equal to the packet break interval and greater than the sleep interval;
cause the receiver circuitry to transition from the sleep state to the active state at the conclusion of the snooze interval; and
receive a second signal packet transmitted by the wireless device.
