1. An apparatus for controlling a facility, the apparatus comprising:
an interface for communicating with window controllers that are communicatively coupled to a control network configured to control the facility; and
a network controller operatively coupled to the window controllers and to the interface, which network controller is included in the control network, which network controller is configured to cause:
(i) sending a status request from the network controller to one or more of the window controllers, the status request requesting a current tint status of one or more optically switchable devices that are disposed in the facility and that are controlled by one or more of the window controllers,
(ii) processing status information received at the network controller from the one or more of the window controllers responsive to the status request, the status information indicating at least the current tint status of the one or more optically switchable devices controlled by the one or more of the window controllers, and
(iii) sending, responsive to processing the status information, one or more tint commands via the interface to the one or more of the window controllers.
