    Abstract: Various embodiments herein relate to power distribution networks for optically switchable windows. In some embodiments, a system for monitoring and maintaining a power distribution network of optically switchable windows of a site is provided. The system includes a control panel monitor which is configured to determine a control panel voltage and current at a terminal of a control panel. The system further includes sense circuitry which is configured to determine a first window controller voltage and current for a first window controller of a plurality of window controllers. The system further includes one or more controllers which are configured to generate voltage network data based on a combination of the control panel voltage and current and the first window controller voltage and current. The system then determines an error condition in the power distribution network based on the voltage network data.

    Abstract: A site monitoring system (SMS) may analyze information from one or more sites to determine when a device, a sensor, a controller, or other structure or component associated with a network of optically switchable devices has a problem. The system may, if appropriate, act on the problem. In certain embodiments, the system learns customer/user preferences and adapts its control logic to meet the customer's goals. In various embodiments, the system updates a memory component associated with one or more optically switchable windows and/or controllers. The memory component may be updated to reflect an updated control algorithm and/or associated parameters in some cases.

    Abstract: This disclosure relates generally to optically-switchable devices, and more particularly, to systems, apparatus, and methods for controlling optically-switchable devices. In some implementations, an apparatus for controlling one or more optically-switchable devices includes a processing unit, a voltage regulator and a polarity switch. The processing unit can generate: a command voltage signal based on a target optical state of an optically-switchable device, and a polarity control signal. The voltage regulator can receive power at a first voltage and increase or decrease a magnitude of the first voltage based on the command voltage signal to provide a DC voltage signal at a regulated voltage. A polarity switch can receive the DC voltage signal at the regulated voltage to maintain or reverse a polarity of the DC voltage signal based on the polarity control signal. The polarity switch can output the DC voltage signal at the regulated voltage and at the polarity based on the polarity control signal to power the optically-switchable device. In some other implementations, the apparatus includes a processing unit, an energy storage device, and first and second voltage regulators.
