Abstract
A method of operating an electrochromic device comprising: coupling a logic device to the electrochromic device; applying a voltage to the electrochromic device; receiving a current from the electrochromic device in response to the provided voltage; and with the logic device, determining an exact operating condition of the electrochromic device from the received current. A method of operating a plurality of electrochromic devices comprising: adjusting a frequency of voltage applied to the plurality of electrochromic devices, wherein each of the plurality of electrochromic devices is adjusted by a different frequency; measuring a duration of time required to change tint states of each of the electrochromic devices; and identifying a location of each of the plurality of electrochromic devices in response to the measured duration of time required to change the tint states of each of the electrochromic device.
