摘要： In some embodiments, a transmitter has a first mode and a second mode. The transmitter is configured to repeatedly send discrete first wireless signals carrying transmitter identification information uniquely associated with the transmitter in the first mode and to send a second wireless signal carrying the transmitter identification information in the second mode. A receiver is configured to receive a wireless signal of the first wireless signals such that the receiver is activated by the wireless signal of the first wireless signal and, in response to receiving the wireless signal of the first wireless signals, to send a third wireless signal carrying the transmitter identification information to the transmitter. The transmitter is configured to transition from the first mode to the second mode in response to receiving the third wireless signal and determining that the third wireless signal includes the transmitter identification information uniquely associated with the transmitter.

摘要： In some embodiments, a method includes receiving a signal indicating that a timeout timer associated with a space has been has crossed a threshold in a space. If a motion sensor is disposed within the space, the method includes sending a signal to a connector operatively coupled to a light source such that the connector reverts to a default state. If (1) a motion sensor is not disposed within the space and (2) a light sensor is disposed within the space, the method includes sending a signal to the connector such that the connector is controlled by the light sensor.
