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.

The embodiments herein relate to methods for controlling an optical transition and the ending tint state of an optically switchable device, and optically switchable devices configured to perform such methods. In various embodiments, non-optical (e.g., electrical) feedback is used to help control an optical transition. The feedback may be used for a number of different purposes. In many implementations, the feedback is used to control an ongoing optical transition. In some embodiments a transfer function is used calibrate optical drive parameters to control the tinting state of optically switching devices.

According to an electrochromic element of the present disclosure, when maximum and minimum optical densities in a coloring region face when an inter-electrode distance is constant are ΔOD.sub.max and ΔOD.sub.min, respectively, the electrodes distance d′=d+δd (d: an inter-electrode distance when the inter-electrode distance of a pair of electrodes is constant, δd: an inter-electrode distance correction amount) at a position providing ΔOD.sub.min, and when an optimal inter-electrode distance correction amount Δd.sub.0 calculated when an optical density difference between ΔOD.sub.max and ΔOD.sub.min is completely eliminated at the position providing ΔOD.sub.min is defined as equation: δd.sub.0 (ΔOD)=d×(ΔOD.sub.max/ΔOD.sub.min−1), δd at a position providing ΔOD.sub.min is smaller than or equal to the maximum value δd.sub.0, MAX of δd.sub.0 (0<ΔOD<D) at 0<ΔOD<D and larger than or equal to δd.sub.0 (ΔOD=D) at ΔOD=D.

An electrochromic device is structured to restrict moisture permeation between an electrochromic stack in the device and an external environment. The electrochromic device includes conductive layers and one or more encapsulation layers, where the encapsulation layers and conductive layers collectively isolate the electrochromic stack from the ambient environment. The encapsulation layers resist moisture permeation, and at least the outer portions of the conductive layers resist moisture permeation. The moisture-resistant electrochromic device can be fabricated based at least in part upon selective removal of one or more outer portions of at least the EC stack, so that at least the encapsulation layer extends over one or more edge portions of the EC stack to isolate the edge portions of the EC stack from the ambient environment. The encapsulation layer can include one or more of an anti-reflective layer, infrared cut-off filter, etc.
