Detailed description

Energy Efficiency

The usage of automated functions already save energy in every installation. Especially the usage of KNX has a lot of potential for further energy savings, which can contribute to a better environmental footprint. Be extending KNX to more functions and applications, energy savings of up to 60% can be realised. Thanks to the flexibility of KNX, these functions can easily be implemented in this installation


Smart homes and buildings are always an upgrade in comparison to a conventional installation. Not only automated functions and a higher level of comfort contribute to a higher living standard, but also the possibility to be ready for coming innovations. Thanks to the usage of KNX, the door has been opened to integrate new innovative solutions, using the worldwide STANDARD for home and building control.

Ease of Use

By integrating KNX, we automatically experience a higher energy efficiency and comfort. Furthermore, by the possibility to use further devices, in order to make the usage of the project easier, we can look at further opportunity to even make the whole installation easier in usage.

Customer's description

SUMAMO co., Ltd one of the first KNX integration companies in Japan. we have been using KNX since 2016 and wanted to make something big in the Automation industry in Japan. so we have decided to open The first KNX showroom to be the smartest building in All Japan. the challenges weren't easy, especially that we have decided to control almost everything in the building starting from light to the TVs and camera. to do so we have used KNX as the backbone of the building for other systems like DALI, DMX Philips, and so on. after a long time of planning, we have reached our goal to control lighting, blinds, HVAC, AV, IP cameras, intercom, all kinds of sensors through KNX. in addition to the normal wall switches, we are controlling the building through motion sensors and voice control by SIRI, Alexa, and google assistant. also, we connected all the buildings to an AI server with cameras to get a notfiv\cation and open the door for the building members automatically.
