1. A method for determining and correcting for changing electrical attributes of a switchable optical device, the method comprising:
applying a drive voltage to a window comprising the switchable optical device to control an optical state of the switchable optical device;
measuring electrical data of the window indicative of the performance and/or response of the window at an initial point in time;
measuring electrical data of the window indicative of the performance and/or response of the window at another time later than the initial point in time;
determining a change in the electrical data based on the electrical data measured at the other time and the electrical data measured at the initial point in time, the change in the electrical data indicating a change in the performance and/or response of the window;
in response to determining the change, adjusting at least one attribute of the drive voltage provided to the window to correct for the change in the performance and/or response of the window;
determining a leakage current associated with the window at the other time based on the determined change in the electrical data of the window; and
wherein adjusting the at least one attribute of the drive voltage is performed if the determined leakage current is outside an expected performance region.
