Cloud forecasting for electrochromic devices

A system comprising:

• a memory;
• and
• a processing device, operatively coupled to the memory, the processing device to:
• identify a plurality of images corresponding to sky conditions;
• isolate cloud pixels from sky pixels in each of the plurality of image, wherein to isolate the cloud pixels from the sky pixels, the processing device is to determine a cloud mask that is a binary segmentation mask and comprises the cloud pixels in a first color and the sky pixels in a second color that is different from the first color;
• responsive to determining percentage of cloud pixels in one or more of the plurality of images meets a threshold value, determine predicted cloud movement relative to sun position;
• and
• cause a tint level of an electrochromic device to be controlled based on the predicted cloud movement relative to the sun position.

A non-transitory machine-readable storage medium storing instructions which, when executed cause a processing device to perform operations comprising:

• identifying a plurality of images corresponding to sky conditions;
• isolating cloud pixels from sky pixels in each of the plurality of images, wherein the isolating of the cloud pixels from the sky pixels comprises determining a cloud mask that is a binary segmentation mask and comprises the cloud pixels in a first color and the sky pixels in a second color that is different from the first color;
• responsive to determining percentage of cloud pixels in one or more of the plurality of images meets a threshold value, determining predicted cloud movement relative to sun position;
• and
• causing a tint level of an electrochromic device to be controlled based on the predicted cloud movement relative to the sun position.
