Abstract: Programmable control devices that rely on time-of-day accuracy maintain that accuracy by determining their location via a global positioning system, recording and timestamping continually measured ambient light via a daylight sensor and real-time clock (RTC) of the programmable control device, determining a mid-darkness time point, comparing that mid-darkness time point with a reference mid-darkness time point for the same location for the same day of the year, and then adjusting the RTC of the programmable control device as necessary. Methods of maintaining time of day in a programmable control device are also provided, as are other aspects.

Abstract: In an approach to generating a wake-up advertisement to a remote device, a system includes: a computing device comprising communications circuitry, including an advertisement initiation circuitry; one or more computer processors; one or more non-transitory computer readable storage media; and instructions stored on the one or more non-transitory computer readable storage media for execution by at least one of the one or more computer processors. The instructions include: send one or more wake-up advertisements to one or more remote devices; receive one or more connection advertisements from the responding remote device; and responsive to receiving the one or more connection advertisements from the responding remote device, connect to the responding remote device.

Abstract: In an approach to networking devices using an ephemeral mesh network, the system includes: a plurality of devices, each device of the plurality of devices further comprising a wireless interface to communicate with a mobile device; and a controller. The controller includes circuitry configured to connect to the mobile device; authenticate the mobile device; responsive to authenticating the mobile device, establishing a mesh network of the plurality of devices, wherein each light device connects to at least one other devices of the plurality of devices to create a mesh network; and responsive to disconnecting from the mobile device, dissolving the mesh network by disconnecting each device from the plurality of devices.

Abstract: A programmable lighting control system integrates time-based, sensor-based, and manual control of lighting and other loads. The system includes one or more groups of controlled lighting areas, which may be, e.g., floors of a building. Each group may have one or more lighting zones, which may be, e.g., individual rooms or offices on a building floor. Each lighting zone includes occupancy and/or daylight sensors that may be wirelessly coupled to a gateway of the group. Each gateway is coupled to a network, such as, e.g., a local area network (LAN). Control software, residing on a computer (e.g., a personal computer or a server) coupled to the network and accessible via the network, remotely communicates with and controls the lighting zones either individually, groupwise, or globally. Each lighting zone can also be locally controlled at the gateway and can function independently of the control software and the gateway.
