  • Patent number: 10149370
    Abstract: 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.
