    • 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.
    • 提供至少部分安全的通信环境,其中附件设备可以在可移动屏障操作员系统的上下文中进行通信并被控制。 在一个示例性方法中,网关设备可以被配置为以安全的方式来协调和控制这样的通信。 这种通信环境的三个示例方法包括:网关设备接收附件设备控制信号,并向目标附件设备发送基于滚动码的附件命令信号; 接收基于滚动码的辅助设备控制信号并向附件设备发送命令信号; 以及接收基于滚动码的辅助设备控制信号,并向目标附件设备发送基于滚动码的附件命令信号。 组合是可能的。 集成系统提供响应于一个或多个其他设备的状态变化的一个设备的自动功能。
