Visible light sensor configured for detection of glare conditions
A device may be configured to detect a glare condition and may comprise a photo sensing circuit and a visible light sensing circuit. The photo sensing circuit may be configured to periodically generate an illuminance signal that indicates an illuminance value. The visible light sensing circuit may be configured to periodically record images of the space at an exposure time. The device may receive an illuminance signal from the photo sensing circuit and determine a present illuminance based on the illuminance signal. The device may adjust the frequency at which the visible light sensing circuit records images based on the present illuminance. The exposure time may be determined based on the present illuminance and a glare condition type. An image recorded at a respective exposure time may wash out pixels above a certain illuminance value. The device may detect a glare condition at the location of washed out pixels.

Automated commissioning of controllers in a window network
In one aspect, a method, system, and/or computer program product is described for generating a graphical user interface for providing information and controlling optically switchable windows connected by a network. Windows are graphically represented using interactive smart objects that are placed within views of the graphical user interface in a manner corresponding to their physical location. In another aspect, a method, system, and/or computer program product is described for associating network IDs of optically switchable windows with the locations at which the windows are installed. Window locations are determined by analyzing received wireless transmissions that are sent from transmitters associated with each of the optically switchable windows. The determined locations are then compared with a representation of the building that provides the window locations. Upon comparison, the network ID of each window, which is communicated through eh window transmissions, is associated with the appropriate window location on the representation of the building.
SELF-CONTAINED EC IGU
Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.
