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: Example methods and apparatus for controlling gas flow in grills based on position data detected via rotary encoders. An example grill includes a burner valve, a rotary encoder, and a controller. The burner valve is movable between an open position and a closed position. The rotary encoder includes a rotatable portion and a fixed portion. The control knob is mechanically coupled to the rotatable portion. The rotatable portion is rotatable relative to the fixed portion. The rotary encoder is to detect a rotational position of the control knob. The rotational position of the control knob corresponds to a rotational position of the rotatable portion relative to the fixed portion. The controller is in electrical communication with the rotary encoder. The controller is to determine a target position of the burner valve based on the rotational position of the control knob. The controller is to instruct the burner valve to move to the target position.
