Abstract: Example methods and apparatus for communicating control signals in a gas grill are disclosed herein. An example user-interface assembly for use in a grill includes control knob, knob sensor to detect a user interaction with the control knob, lighting circuitry including a plurality of light emitting diodes, and user-interface controller circuitry to identify an addressing block connected via an input wiring harness, the knob controller to select an address to be used to communicate with a central controller of the gas grill.

Abstract: Methods and apparatus to indicate presence of a flame are disclosed. An example gas grill includes a burner tube having apertures to emit a fuel for combustion, an ignition element to cause ignition of the fuel emitted from the apertures of the burner tube, a flame sensor to detect the presence of a flame associated with the combustion of the fuel emitted from the apertures of the burner tube, and flame sense circuitry including a flame signal accessor to access a flame sense signal from the flame sensor, and a terminal to output an indication of the presence of the flame, the indication of the presence of the flame output without respect to an open or closed state of a lid of the grill.

Abstract: Example methods and apparatus for supplying configuration data to controllers of grills are disclosed. An example grill includes a controller and a dongle. The dongle is connectable to the controller. The dongle includes memory storing configuration data associated with the grill. The controller is to read the configuration data from the memory in response to the dongle being connected to the controller.
