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; and
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, wherein measuring the electrical data comprises measuring a current response to the applied drive voltage, the measuring comprising measuring the current response to a component of a profile of the applied drive voltage.
