1. A method to control one or more functions of a spa, the method comprising:

  • receiving user input using capacitive sensing to adjust at least one spa function, wherein the capacitive sensing comprises;

    detecting when an object is in proximity of an oscillator, wherein the oscillator is operable to vibrate when an object is in proximity of the oscillator, and wherein a capacitance of the oscillator is a function of the proximity of the object with the oscillator;

    detecting a vibration of the oscillator when the object is in proximity of the oscillator;

    changing a status of a control device in response to detecting the vibration; and

    adjusting the at least one spa function based on the changing of the status of the control device.
