US Patent 10921675 Cloud-based system for controlling electrochromic devices

A system for causing electrochromic devices to be controlled is described. The system may include a memory and a processing device coupled to the memory. The processing device may receive a data stream from a driver controlling a set of electrochromic devices, transmit a first subset of the data stream to a server device, and store at least a second subset of the data stream in a data file in the memory. The processing device may receive one or more instructions from the server device and transmit the one or more instructions to the driver to cause the set of electrochromic devices to be controlled based on the one or more instructions.
