A method includes identifying images corresponding to sky conditions. The method further includes isolating cloud pixels from sky pixels in each of the images. Responsive to determining percentage of cloud pixels in one or more of the images meets a threshold value, the method further includes determining predicted cloud movement relative to sun position by tracking similar feature points between two or more images of the images. The method further includes causing a tint level of an electrochromic device to be controlled based on the predicted cloud movement relative to the sun position.

Cloud forecasting for electrochromic devices

A method includes receiving first dimensions of an electrochromic device and second dimensions of one or more obstructions of the electrochromic device. The method further includes generating, based on the first dimensions and the second dimensions, an obstruction map that indicates at least one of an obstructed portion or an unobstructed portion of the electrochromic device. The method further includes determining, based the obstruction map, a first desired tinting state of the electrochromic device. The method further includes causing a current tinting state of the electrochromic device to correspond to the first desired tinting state.

Automated control of an electrochromic device

A method includes identifying a plurality of images corresponding to sky conditions and isolating cloud pixels from sky pixels in each of the plurality of images. Responsive to determining percentage of cloud pixels in one or more of the plurality of images meets a threshold value, the method further includes determining predicted cloud movement relative to sun position. The method further includes causing a tint level of an electrochromic device to be controlled based on the predicted cloud movement relative to the sun position.

Automated control of an electrochromic device is described. A method includes receiving a first image captured from a first viewpoint of an electrochromic device. The method further includes identifying at least one of an obstructed portion of the first image or an unobstructed portion of the first image. The method further includes generating an obstruction map based on the at least one of the obstructed portion of the first image or the unobstructed portion of the first image. The method further includes determining, based on the obstruction map, a desired tinting state of the electrochromic device and causing a current tinting state of the electrochromic device to correspond to the desired tinting state.
