Abstract

Controllers for providing functions for windows capable of undergoing reversible optical transitions. In some cases, the controllers have multiple features that can sense and adapt to local environmental conditions. The controllers can be integrated with a building management system (BMS) to greatly enhance the BMS's effectiveness at managing local environments in a building. For example, controllers may control one or more functions such as powering a smart window, determining the percent transmittance, size, and/or temperature of a smart window, providing wireless communication between the controller and a separate communication node, etc.
