Abstract
An at least partially secure communication environment is provided in which accessory devices can be communicated with and controlled in the context of a movable barrier operator system. In one example approach, a gateway device can be configured to coordinate and control such communications in a secure manner. Three example approaches to such a communication environment include: a gateway device's receiving an accessory device control signal and sending a rolling code based accessory command signal to a target accessory device; receiving a rolling code based accessory device control signal and sending a command signal to an accessory device; and receiving a rolling code based accessory device control signal and sending a rolling code based accessory command signal to a target accessory device. Combinations are possible. An integrated system provides for automatic functioning of one device in response to status changes of one or more other devices.
