With the inclining popularity of smart home and smart building applications, related technologies are being updated and iterated rapidly. KNX, as the world's first international standard based on smart home and building control, is integrated and standardized from the original three technical protocols of EHS, BatiBUS, and EIB, aiming to guarantee more comfortable, safer, and more energy-saving residential and building control systems. Products of different performances and manufacturers can be configured and debugged in the same software as long as they pass the KNX certification to achieve interconnection and interoperability between devices; at present, the KNX bus control system has been applied to many large public buildings in China, such as the national landmark buildings - Bird's Nest and Water Cube project, the world's largest single building --Beijing Daxing International Airport, etc. Because of the stable application of KNX in these mega benchmark projects, it has become the mainstream protocol for high-end wired smart home in China's residential smart home market.

As a Chinese manufacturer member of KNX international organization, NEXhome has many years of mature experience in KNX bus application and is the first smart home manufacturer in China to launch distributed KNX system architecture, which collects many advantages of KNX and achieves innovation in architecture to reconstruct a new face of the wired smart home system. The NEXhome KNX distributed smart home system complies with China's building electrical and mechanical design standards and is compatible with traditional electrical wiring, effectively saving project construction costs; in addition, the after-sales maintenance and upgrade of the product are more convenient and efficient, reducing customers' worries. The specific advantages of the system include the following four major aspects:

1. Down to earth and easy to construct

KNX centralized structure originates from the transplantation of large foreign intelligent building systems, which are applied to the centralized intelligent control of large facilities such as shopping malls, buildings, and stadiums, and migrate to the miniaturized intelligent home environment with high wiring costs and system complexity.

2. Simple structure, easy to expand

NEXhome distributed KNX system has the largest flat structure compared to the centralized KNX system, and like traditional home electrical, no centralized wiring is required, only a KNX special communication line is needed to realize power supply and communication, which reduces the complexity of implementation and makes upgrading and expansion more flexible. The common centralized KNX wired smart home system in the market adopts the way of centralized control, which requires control modules and control loops to be installed in the aggregate, requiring special planning of installation space and wiring methods in advance, and resulting in huge electromagnetic radiation due to the aggregation of all strong electrical lines; while the NEXhome distributed KNX structure directly adopts indoor zoning wiring, which is free of radiation troubles and more green and safe.

3. Low total cost, high efficiency

All switches in the common centralized KNX system need to be interconnected by a bus. All light control lines are connected to the strong power box, which requires the deployment of special networks and distribution cabinets for smart homes, with a large amount of server room deployment, suitable for villa use only. The wire cost and construction cost of wiring is inclined. If the centralized KNX system in the centralized control module fails, it will lead to the whole area lights are not controlled, must replace the original module to restore the use of labor costs and intelligent construction costs to be more than three times the distributed type.

NEXhome distributed KNX system does not change the existing wiring, the deployment of the server room can be reduced by 90%, and wiring space can be saved by 60%. If the distributed switch fails, the failed switch can be replaced individually, and the emergency does not affect the opening and closing of lights in other areas, nor does it affect the function of other areas. NEXhome distributed KNX system wiring is compatible with the standard wiring method, no need to train electricians to achieve rapid construction, wiring costs, and labor costs are lower than the centralized type.

4. Smart configuration, easy delivery

To simplify the debugging process of batch delivery, NEXhome for smart home batch project debugging workload, repeat labor more industry pain points, developed a special cell phone configuration APP, the same house type to generate a template can be reused to implement; construction environment miniaturization, staff only need a cell phone to achieve efficient delivery of smart home projects, greatly improving efficiency and reducing debugging costs.

After the delivery of the project, the owner can scan the central control QR code through the smart home APP to quickly complete the identity authentication, bind the whole house smart system and instantly experience the whole house smart system control.

At present, NEXhome's distributed KNX system has been seamlessly connected with smart devices of major international manufacturers and successfully applied to many head real estate smart home batch projects, empowering them efficiently and constructing new smart home systems.

NEXhome will continue to realize a more comfortable, safe, and healthy smart home life for more users with its innovative products and strong technical advantages.
