Knx Ip Baos 777 Update De 2020 003

The KNX IP BAOS 777 is a powerful universal device for KNX installation: Thanks to the integrated web server, the device enables the visualization and control of buildings, rooms and functions in a standard web browser on a PC or mobile devices such as smartphones and tablets.

The new, integrated e-mail function allows individual notification of several recipients, e.g. in case of status changes or an alarm. The integration of a Date & Time Server (NTP) makes it possible to obtain the date and time automatically via the Internet and to synchronize one’s own KNX installation. Extensive time functions allow the realisation of a powerful KNX time switch with weekly function.

The configuration is done exclusively with the ETS software – no extra software or tool is required.

The device also offers the function of a KNX IP interface (KNXnet/IP), for example as a programming interface for the ETS. Developers can access all functions via an API with BAOS RESTful Web Services. This allows the device to be used as an application-specific gateway, connecting the KNX bus to the existing IP infrastructure.

Best in Class: the KNX IP BAOS 777 represents a powerful residential gateway for building control with smallest size and minimal power consumption.

NEW: Visualization and Control

The KNX IP BAOS 777 has an integrated web server that allows access to the visualization and device settings via a web browser. The modern interface of the visualization allows the control of the entire KNX installation divided into the individual rooms and functions.

The configuration is done easily and consistently via the parameter dialogues of the ETS. The visualization is generated dynamically and automatically in the device after each download via the bus or network. No additional tool or app is required.

The newly designed user interface of the device (free download of the latest firmware) is not only visually refreshed, but also offers numerous new functions. For example, alarms are now displayed via the animated function icons as well as via notification icons in the main view of the visualization.

Also new: a filter function allows quick and targeted finding of individual functions and timers in the installation.

Visualisation Alarm

Supported Functions

The data is displayed graphically in the browser and the functions can be operated directly – optimized for use on touch interfaces.

The following functions are supported:

NEW: Email Notifications

E-mail notifications now allow immediate information about the current status and changes in the KNX installation.

The easy-to-configure e-mails are always sent when the value of the selected data point meets the configured condition.


In the web interface, the individual email notifications can be shown or hidden for a better overview.

NEW: Date & Time

DaThe current date and time of the device – these can now be set either manually or via an NTP (Network Time Protocol) server.

Settings Date Time1

With this feature the whole KNX installation can now be supplied with the manually set or externally synchronized time. 

Programming Interface

The KNX IP BAOS 777 can be used as an 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 the ETS® or other programs that support KNXnet/IP tunnelling. It supports up to 8 simultaneous connections.

Residential Gateway

The KNX system is based on a special protocol that is difficult to implement for non-KNX devices. Using Weinzierl’s BAOS architecture, the device maps KNX data to an IT-friendly API (Application Programming Interface). This considerably reduces the effort to connect external applications such as control systems or visualizations with KNX.

The KNX BAOS architecture allows not only access to the runtime data but also to the structure of the KNX installation. All information about rooms of a building as well as the available functions can be read out by a client as metadata. With the help of ETS, the rooms and the functions that should be available to the user are defined.

Info1KNX IP BAOS Protokoll

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 device also offers time and recording functions, which are available via the BAOS protocol.

Application Specific Gateway

The KNX IP BAOS 777 can be used as an application specific gateway for connection to non-KNX systems. It can be used, for example, to integrate heating systems or audio applications with ETS integration into the KNX system. For development purposes, the generic ETS product database is available, which offers up to 2 000 data points as a flat list. The data point types can be configured individually via ETS parameters. Of course, own ETS product entries can be developed.


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.
