A garage door opener system having a garage door opener and a remote input device electrically connected to the garage door opener by an electrical conductor. The remote input device receives power by the electrical conductor. The remote input device includes a device controller to communicate an event message, monitor for an acknowledgement message within a time period, and repeat the event message when the acknowledgement message is not received within a time period. The garage door opener includes a master controller. The master controller receives the event message and communicates the acknowledgement message in response to receiving the event message. Also disclosed is a method of operating the garage door opener system.

A rear door control system includes an electronic controller connected to a rear door movement device, a keyfob sensor array, a movement detection sensor, and a projector. The electronic controller determines whether or not a movement gesture made by the individual standing within a prescribed location relative to the rear door is a conforming gesture, and in response to determining that the movement gesture is a conforming gesture, the electronic controller operates the rear door movement device to open the rear door in further response to a determination that the authorized keyfob is present. As well, in response to determining that the movement gesture is not a conforming gesture, the electronic controller operates the projector to project an image indicating that the movement gesture is not a conforming gesture, leaving the rear door in the closed orientation.
