@thaliquids I would tackle this by finding a controller (here's a few examples of controllers: https://www.mysensors.org/controller) that supports Philips Hue. The controller would then get an event each time a button is pressed on the tap. Then you link a script or other action to that event which switches the tube light on or off. The advantage of using a controller is that the corresponding action can be done on a device totally different from Hue (MySensors, Sonoff, Z-Wave etc.)
