This smart switch system enables the control of curtains, lights and air conditionings with ease. Thus, users can create their own ambience. In the sleep mode, for example, the lights slowly dim, the curtains close and the room temperature is adjusted to a pleasant level. The panel comes in a range of materials and colours, which allows it to integrate well into the respective interior. A userfriendly feature is that content, size and brightness of the lettering on the switch can be customised to personal taste.
