KNX SERVER, the customized visualisation solution

DIVUS KNX SERVER is the core of the web technology based visualization solution of DIVUS for KNX systems, which gives you full control over the functions of your home. KNX SERVER has been refitted and now provides – among a noticeable performance boost – the new OPTIMA interface for creation of design-oriented visualizations.

From the KNX-M-SERVER to the KNX-E-SERVER – scaleable visualisation solutions

Our new KNX SERVER family covers the whole gamut of requirements in this sphere, from a cost efficient basic server that is an ideal entry-level gateway to the world of visualisation up to a server where the sky’s genuinely the limit, which can be used for large-scale projects and adapted to required needs.

*Support of selective import: select and import only the group addresses really needed for visualisation!


The KNX-M-SERVER (Mini-SERVER) operates in concert with mobile devices in the Apple domain (iPhone, iPad and iPod), as well as with Android devices such as myriad smartphones and tablet computers from vendors such as Motorola, Acer, Huawei, and many more.

And when it comes to stationary operation, the KNX-M-SERVER can communicate with our Android-based DIVUS TOUCHZONE. For all supported Android products, in addition to access to KNX visualisation a SIP-based door communication app is available that can be used via our INTERCOM UPGRADE, also with our KNX-M-SERVER. This in turn allows the DIVUS TOUCHZONE to become an indoor-station for door communication. In addition to our own OPENDOOR outdoor station, those of Siedle, Jung, Gira, TCS and many other vendors are supported as well.


Our next-largest server, the KNX-H-SERVER (Home-SERVER) is a must when it comes to meeting customers’ ever growing expectations as regards functionality and design. These solutions are increasingly coming into use in middle to upper class private-sector real estate (apartments and homes), as well as in smaller commercial properties such as medical practices, retail stores, offices, and production facilities.

Our KNX-H-SERVER not only offers an expanded range of functions, but also supports a full graphics mode, which allows for placement of system functions right on the background image. Both classic layout plans as well as actual images of a given space can be used as background. Depending on the functions an object supports, having been put in position it can be either activated directly or can serve as a gateway to extended entry options. The onscreen menu bar allows for user friendly navigation and features a tree view of the relevant spaces (for rapid opening of the desired pages) as well as dedicated areas for the management of functions such as light, climate, shading, security and the like.

KNX Advanced SERVER & KNX Enterprise SERVER

This menu also provides access to various plugins that allow for management of additional functions such as scenarios and provides access to web content, weather reports, news tickers, and message boards. The next step up – our KNX-A-SERVER (Advanced- SERVER) – is designed for use in large private sector properties or commercial buildings. The only difference to the KNX-H-SERVER is the higher limitation for group addresses and energy counter creation.

Our top of the line server, where the sky’s genuinely the limit, is our KNX-E-SERVER (Enterprise-SERVER), which can be used for large-scale projects and adapted to their requirements.

DIVUS Project Development Kit

With the new PDK, DIVUS offers you a powerful software tool for the products of the KNX CONTROL family, which can be used in many ways:

  • Create projects for KNX SERVER / KNX SUPERIO directly on the own PC, without connection to the hardware itself
  • Become acquainted with the functionalities of the new OPTIMA interface
  • Use the tool as demo software for product presentations


DIVUS OPTIMA – the interface to your system

Both KNX SERVER and KNX SUPERIO will show the functions of your system in a stylish and intuitive way: through the OPTIMA interface.

Thanks to the integrated web support, the interface can be shown on all kind of devices with a compatible browser and will automatically adapt its contents to the different conditions (resolution, size …). The use of the interface has been optimized for devices with touchscreen and – beneath the control of the KNX system – offers a huge amount of additional functionalities.



In DIVUS OPTIMA it is generally possible to record electrical loads graphically. The UP-DATALOG-SW extends this feature, so that a free configuration of graphs of arbitrary values, such as temperatures, brightness, status feedback, percentage values etc. is possible. Various types of graphical representation are available, whereby the respective graphical output may be optimally adapted to the respective purpose. This allows the user to gain the easiest and fast way an overview of the current situation.

INTERCOM-Software Upgrade

In the standard version of DIVUS OPTIMA the Intercom support is limited or not available (KNX-M-SERVER) depending on the specific KNX CONTROL product. With the UP-INTERCOM-SW the Intercom support can be extended in DIVUS OPTIMA to 20 internal units and 10 external units. This is necessary especially in larger systems, for example if multiple entrances are provided with a door station or numerous indoor units are present in the installation.

The KNX-M-SERVER has no intercom support in the basic edition. Nevertheless, if the intercom functionality is needed, with the UP-INTERCOM-SW also on the KNX-M-SERVER the intercom support for 10 external units and 20 internal units can be enabled.


INTERCOM-Hardware Upgrade

For the integration of analog door communication systems in OPTIMA, the special bundle UP-INTERCOM-HW was created, which includes the required hardware (Videophone-Box) and the UP-INTERCOM-SW. With this special package supported analog door communication systems can therefore be used in conjunction with KNX SERVER or KNX SUPERIO.


Thanks to the use of NFC technology (Near Field Communication) the control of smart homes is even easier and more comfortable now. DIVUS SMART-ITs can be stuck anywhere (hidden or visible) in the house. In combination with a smartphone, different home control functions can be activated in a quick and uncomplicated way.

It is very easy to configure the little smart tags, which contain an ultra-thin chip. Various commands can be created and saved in just a few steps.
Before going to sleep, hold the smartphone close (max. 3 cm distance) to the SMART-IT with the programmed function “Good Night” and the alarm system will be activated automatically, the blinds lowered and all the lights switched off in the house except of the the bedside lights.
Or when entering the living room, move the smartphone over the SMART-IT called “Feel good”, immediately your favorite music will be played, the lights dimmed and a comfortable temperature reached.

The system integrator programs the SMART-ITs in the administration menu according to customers’ wishes. The customer needs only to decide where to place the SMART-ITs in the house. With a NFC-enabled smartphone and the app of DIVUS, desired commands can easily be activated. The shortcuts saved on the NFC-chip are sent from the smartphone to the server and executed automatically when activated.


With this upgrade, the KNX SERVER can send and receive SMS messages. Depending on freely definable events, the
user can easily be informed via SMS about various circumstances. Furthermore it is possible to remotely activate
actions via SMS through the KNXSERVER. In this way, you stay always connected to your home.
*The UP-SMS is available for KNXSERVER only


With UP-MODBUS-SW, the KNXSERVER can be connected via modbus protocol with other modbus devices. Thereby
it is possible to establish the connection by cable or by modbus TCP/IP via the local network. In this way, third-party
systems can be implemented via the modbus standard into the visualization.
