ABSTRACT:
A visual display panel is mounted on the exterior surface of a power-operated garage door to display messages for viewing by occupants of a departing automobile after the garage door has closed. The display panel may be part of an integrated home automation system (IHAS) so that, in addition to pre-programmed messages, the operational status of household devices included in the IHAS are presented on the display panel. Actuation of the garage door operator to open the garage door can also cause the IHAS to direct changes in the operation of one or more of the included devices.
