  • Publication number: 20190254146
    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.

  • Publication number: 20180103411
    Abstract: In some embodiments, a method includes receiving, at a first wireless device of a plurality of wireless devices, a data packet including an indication of a source of the data packet. In response to the first wireless device being associated with the source of the data packet, whether the first wireless device is a local repeater can be determined based on at least one of a random number or a number of wireless devices of the plurality of wireless devices. In response to the first wireless device being determined to be a local repeater, the first wireless device can be caused to be configured as a local repeater such that the first wireless device sends the data packet to at least one remaining wireless device of the plurality of wireless devices.
