A gas barbecue having a cut-off valve situated between a gas inlet and a gas burner. According to some implementations the cut-off valve has a control knob moveable to a first position and a second position, in the first position of the control knob the cut-off valve is maintained in an open position, in the second position of the control knob the cut-off valve is placed under the control of an electrical control unit that acts upon an electromagnet assembly of the cut-off valve to control the open and close position of the cut-off valve. When the control knob is in the second position the electrical control unit is able to wirelessly exchange information and/or instructions with a remote control unit, whereas when the control knob is in the first position the electrical control unit is unable to wirelessly exchange information and/or instructions with the remote control unit.
