Software applications are used for controlling the optical state of one or more optically switchable windows or other optical products installed in a structure such as building. The applications permit users to send and/or receive data and/or commands for controlling the switchable optical products. In some embodiments, the applications provide an interface with a window network controller, which directly or indirectly controls windows in a structure. Relevant processing involving the application may include user authentication, commissioning, adaptive control, and decisions on whether to permit an action or change requested by a user. In some embodiments, the application allows users to directly control the tint state of one or more tintable windows. In some embodiments, the application allows users to change a rule or property associated with controlling a switchable optical product.

Thin-film devices, for example, multi-zone electrochromic windows, and methods of manufacturing are described. In certain cases, a multi-zone electrochromic window comprises a monolithic EC device on a transparent substrate and two or more tinting zones, wherein the tinting zones are configured for independent operation.

A high-speed data communications network in or on a building includes a plurality of trunk line segments serially coupled to each other by a plurality of passive circuits configured to deliver signals to, and to receive signals from, one or more devices on, in, or outside the building, wherein the signals comprise data having a greater than 1 Gpbs transmission rate.

Disclosed herein are systems, apparatuses, methods, and non-transitory computer readable media related to a display construct coupled to a structure (e.g., a vision window such as a tintable window). The structure can be a supportive structure such as a fixture. The display construct is configured to facilitate media display and is at least partially transparent. An interactive installation software tool and process aligns a digital configuration of the display construct and/or touch screen functionality of the display construct, with its physical configuration in a matrix of display constructs.

A method of controlling tint of a tintable window to account for occupant comfort in a room of a building. The tintable window is between the interior and exterior of the building. The method predicts a tint level for the tintable window at a future time based on a penetration depth of direct sunlight through the tintable window into the room at the future time and space type in the room. The method also provides instructions over a network to transition tint of the tintable window to the tint level.

A messaging system for exchanging messages between nodes in a network via a broker that uses a publish-subscribe message protocol, which nodes have object identifications (IDs). Messages between the nodes are routed using the object IDs of the nodes. Secure communication is provided using authentication according to digital certificates being used as first and second tiers by a commissioning broker and a data broker, respectively, in which the second tier certificate used by the data broker has a shorter lived expiration time.

Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device. The applied drive voltage is provided at a level that drives a transition over the entire surface of the optically switchable device but does not damage or degrade the device. This applied voltage produces an effective voltage at all locations on the face of the device that is within a bracketed range. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term. At the lower boundary of this range is an effective voltage at which the transition between optical states of the device occurs relatively rapidly. The level of voltage applied between the bus bars is significantly greater than the maximum value of the effective voltage within the bracketed range.

Certain aspects pertain to a combination sensor comprising a set of physical sensors facing different directions proximate a structure, and configured to measure solar radiation in different directions. The combination sensor also comprises a virtual facade-aligned sensor configured to determine a combi-sensor value at a facade of the structure based on solar radiation readings from the set of physical sensors.

Techniques for transceiving radio frequency (RF) signals through a window of a building are disclosed, the window having a first surface facing an interior of the building. An antenna arrangement is attached to a building structure adjacent the first surface and the antenna arrangement includes one or more radiating elements configured to transceive the RF signals through the window. In some embodiments, the building structure is mullion. In some embodiments a window surface includes an electrochromic and/or low emissivity coating that is excluded from a region proximate to the radiating elements.

A site monitoring system (SMS) may analyze information from one or more sites to determine when a device, a sensor, a controller, or other structure or component associated with a network of optically switchable devices has a problem. The system may, if appropriate, act on the problem. In certain embodiments, the system learns customer/user preferences and adapts its control logic to meet the customer's goals. In various embodiments, the system updates a memory component associated with one or more optically switchable windows and/or controllers. The memory component may be updated to reflect an updated control algorithm and/or associated parameters in some cases.
