The KNX IP BAOS 777 is the logical continuation of the proven KNX IP BAOS series including the KNX IP BAOS 771 and 772. The device is based on a completely newly developed platform with a new design.
Not only the functions and resources of the BAOS protocol were extended, but also a web server was integrated which allows the visualization and control via a Web browser. Thus, the KNX IP BAOS 777 performs the leap from application-specific interface for comprehensive IP Gateway for KNX installations.

   Powerful and universal

The KNX IP BAOS 777 is a very compact (2TE) and yet very powerful IP device for the KNX bus. Despite the small installation width, the device features a graphic display with menu navigation.

The KNX IP BAOS 777 combines the function of a KNX IP interface with the function of a universal IP gateways for building control. It connects the KNX bus with the existing IP infrastructure. The integrated web server enables the visualization and control of buildings, rooms and functions via a standard web browser on a PC or mobile devices such as smartphones and tablets. The configuration is done with the ETS software.

Via the BAOS protocol (e.g. via Web services), the device also enables a technical interface to the KNX installation. This allows the rapid integration of non-KNX devices in a KNX network.











   Programming Interface

The KNX IP BAOS 777 can be used as interface to the KNX Bus on the telegram level. It is compatible with the KNXnet/IP specification and can be used as bus interface for ETS® or other programs that support the KNXnet/IP Tunnelling. It supports up to 8 simultaneous connections.


   Visualization and Control

The KNX IP BAOS 777 has an integrated web server that allows access to the device settings in a web browser on a PC or a mobile device such as a smart phone or a tablet:

Web interface desktop  Web interface mobile  Web interface tablet
With the help of the ETS product entry with building structure and the integrated web server the device also offers visual representations of the entire KNX installation. The data from the residential gateway are graphically displayed in the browser and the functions can be operated directly. Timers are also available via the web server.

   Residential Gateway

The KNX system is based on a specific protocol that is difficult to implement for non-KNX devices. The KNX IP BAOS 777 maps KNX data to an IT-friendly API (Application Programming Interface). It greatly reduces the effort to connect e.g. control or visualization tools to KNX. Also helpful is the storage of all data point values – even if the client device is not connected.

The KNX BAOS architecture not only allows access to the run-time data, but also to the structure of the KNX installation. All information about rooms in a building and the available functions can be read as metadata from a client. With the ETS, the rooms and the functions are defined, which should be available to the user.


KNX IP BAOS protocol

available in three different versions:

  • KNX IP BAOS Binary: A binary protocol that is especially suitable for small microcontroller.
  • KNX IP BAOS Web Services: A URL-based protocol with JSON syntax compatible with KNX IP BAOS 771 and 772.
  • KNX IP BAOS RESTful Web Services: A URL-based protocol with RESTful JSON syntax, which can be integrated into browser-based web applications.

The KNX IP BAOS 777 also has time and recording functions available on the BAOS protocol.


   Application specific Gateway

To connect to non-KNX systems, the KNX IP BAOS 777 can be used as an application specific Gateway (e.g. to connect heating devices, audio applications and many more). In this case the generic ETS product entry (with up to 2000 data points) can be used for development purposes. Of course, individual product entries can be developed. The datapoint types can be individually configured via ETS parameters.



Both for the use of the KNX IP BAOS 777 as a residential gateway as well as for the development of application-specific solutions the BAOS protocol must be implemented in the client. For a quick and easy integration of BAOS Binary Services a free SDK is available. More information about the BAOS SDK and the free download can be found here.



  Weinzierl BAOS CSV Importer


For all Weinzierl BAOS modules and devices, a generic ETS entry is available. It contains a list of all available data points. You can select a data point type and enter a name for each data point. In addition, a so-called DCA (Device Control App) is now available with the Weinzierl BAOS CSV Importer. The Weinzierl BAOS CSV Importer is available for all Weinzierl BAOS devices with a generic ETS product database and is an easy way to export the existing configuration of a generic BAOS database into a CSV file and import it into another project. Thus, a tedious configuration by hand is spared.

The Weinzierl BAOS CSV Importer is available as a free download in the online store of the KNX Association under Shop / ETS-Apps (Creating a user account is necessary). After adding to the shopping cart and check-out you will receive the download link for the Weinzierl BAOS CSV Importer within "My account / Products". You can also download the Weinzierl BAOS CSV Importer here.

Installation instructions and usage documentation are also available here.

Please note: the Weinzierl BAOS CSV Importer requires a commercial license of ETS 5.5 or higher.
