A graphical user interface enables a user to create and modify graphical schedules for a wide variety of devices that may be controlled by a programmable multimedia controller. A graphical schedule graphically depicts a relationship between time and at least one user-selected condition to be satisfied or at least one user-selected action to be taken. The user may create or modify graphical schedules using familiar techniques such as taps and swipes, drag and drop and the like. In another aspect of the invention, a graphical schedule is simultaneously displayed to a user along with pertinent historical information.
