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.

Encrypted communications for a movable barrier environment

Encrypted communications for a moveable barrier environment

A post () for use with an automatically-movable barrier () and a motive actuator () is configured to interact with the barrier to thereby facilitate movement of the barrier with respect to the post. This post can have at least one cavity () formed axially therein and a mains-power-bearing pathway () disposed within this at least one cavity to convey mains electrical power to movable barrier control circuitry () as well as the motive actuator. Such a post can further comprise one or more integral pivot points () that are configured to pivotally engage the automatically-movable barrier such that the automatically-movable barrier can selectively pivot about the integral pivot point. By another approach, such a post can further comprise one or more rollers () that are configured to engage the automatically-movable barrier such that the latter can selectively move in a lateral direction through engagement with the roller(s).
