Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: receiving at a gateway device from a user interface an accessory device control signal designed to implement a function of at least one target device, the at least one target device comprising at least one of a movable barrier operator or at least one of a plurality of accessory devices configured to operate in a movable barrier operator system and configured to communicate status information regarding the movable barrier operator system…
