This multifunctional control knob is very useful for the operation of smart home devices. A simple push or turn is sufficient to manage lighting, curtains, the HiFi or air conditioning. It is easy and intuitive to use. The artistic design emulates the appearance of a large pebble. The casing is made of black plexiglass and metal which creates a striking contrast. As it comes in a variety of different colours, the knob can be combined with a wide range of interiors.
