    Abstract: Wireless lighting control systems and methods for controlling the illumination of one or more light fixtures are disclosed, including self-commissioning of hardware. Embodiments include a server connected to a wide area network and having software for configuring, monitoring, and controlling lighting fixtures at a site. The control system also includes a wireless gateway at the site initiating communication with the server via a cellular network. Wireless devices initiate communication with the wireless gateway via a mesh network and each wireless device can be wired to control at least one lighting fixture. Once hardware of the site system (e.g., a gateway and/or any device) is mounted or positioned in the appropriate location and powered on, the hardware will self-commission by automatically initiating communications. The gateway will initiate communication and identify itself to server system. When the devices are powered on, they identify themselves to the gateway and the gateway can inform the server system of the devices.

    Abstract: An illustrative bi-level dimming controller for coupling to a dimming control input of a lighting driver includes a dimming preset selector for setting a preset dim level, and a dimming control circuit having variable impedance and providing a constant dimming voltage output for a preset dim level, even if the current supplied to or impedance coupled to the dimming controller changes. The dimming control circuit is responsive to the preset dim level to drive a dimming voltage output proportional to the preset dim level. The dimming controller may also include a dim enable circuit responsive to a detection signal to selectively couple and uncouple the dimming signal output with the dimming control input of the lighting driver, thereby providing switching between a preset dim level and a full light level. The detection signal may be electrically isolated from the dimming voltage output.
