Design and materials
Theben's KNX push button. One base unit has 8 buttons, and the rockers you fit (1, 2 or 4) make 2, 4 or 8 of them work. Each button has an RGB status light, and its brightness can follow the room light. The base measures the temperature, the humidity, the light and the indoor air quality, and it senses when someone comes near. It has its own thermostat for heating and cooling, and it takes its power from the KNX bus.

Brushed metal or silky matte
Four brushed finishes: aluminium in grey or black, brass and stainless steel. Six silky-matte finishes: aluminium painted in several layers and sealed, for a soft feel.
A light on each button
Each button has an RGB status light in one of seven colours. Its brightness follows a setting or the light of the room.
It measures the air
The base measures the indoor air quality from the CO2 of the room, in five levels, with the temperature and the humidity. It can send an alarm when a value passes a set threshold.
Where it goes
By the door of each room, on the latch side; Theben advises 1.10 to 1.20 m from the floor.
