Abstract: This disclosure relates generally to optically switchable devices, and more particularly, to methods for controlling optically switchable devices. In various embodiments, one or more optically switchable devices may be controlled via voice control and/or gesture control.

Abstract: A network system in an enclosure includes one or more interactive targets such as tintable windows, HVAC components, sensors, computing devices, media display devices, and/or service devices. Diverse types of local and remote interfaces are employed for facilitating remote (e.g., indirect) manipulation of the interactive target(s), for example, using a digital twin (e.g., representative virtual model) of a facility and/or a mobile circuitry of a user. The environment and/or targets may be controlled according to preferences and/or requests of its user(s).

Abstract: Aspects of this disclosure concern controllers and control methods for applying a drive voltage to bus bars of optically switchable devices such as electrochromic devices. Such devices are often provided on windows such as architectural glass. In certain embodiments, the applied drive voltage is controlled in a manner that efficiently drives an optical transition over the entire surface of the electrochromic device. The drive voltage is controlled to account for differences in effective voltage experienced in regions between the bus bars and regions proximate the bus bars. Regions near the bus bars experience the highest effective voltage. In some cases, feedback may be used to monitor an optical transition. In these or other cases, a group of optically switchable devices may transition together over a particular duration to achieve approximately uniform tint states over time during the transition.
