Remote access in the context of KNX projects
The requirement for remote access to KNX installations is now standard in most projects. Clients expect to operate their systems while away from the building, operators require transparency regarding system status, and system integrators need secure access for service and diagnostics. In many cases, a visualisation server is specified for this purpose. Such systems offer extensive functionality but introduce a separate configuration environment, additional software expertise and dedicated hardware infrastructure.
In small and medium-sized projects, it is therefore appropriate to question whether the functional and economic effort of a conventional KNX visualisation system is always justified. Not every installation requires individually designed graphical user interfaces, complex logic functions or a server-based architecture with advanced user management.
Consistent configuration within ETS
The Zennio RemoteBOX ZSYRBOX follows a deliberately streamlined approach. It enables remote access via the Zennio Remote platform without introducing additional visualisation software. All configuration is performed within ETS. Communication objects are parameterised as usual and assigned to the required controls. Duplicate data maintenance or synchronisation between different project files is avoided.
For system integrators, this results in direct integration into established workflows. No training in a separate visualisation tool is required and the system architecture remains clearly structured. The RemoteBOX manages up to 100 controls as standard, distributed across a maximum of 12 configurable pages. This allows a typical residential installation or a small commercial building to be represented in a clear and practical manner.
Relying exclusively on ETS as the central configuration platform reduces interfaces and potential sources of error. Changes within the KNX structure can be implemented without detours, which is advantageous both during commissioning and in later extensions.
Cost efficiency and scalability
Economic considerations are a key factor. By eliminating the need for a dedicated visualisation server, not only hardware costs but also engineering and commissioning effort are reduced. Project timelines remain manageable and the solution can be calculated transparently. For integrators, this means a clear quotation structure without additional software licences or complex server configuration.
At the same time, the system remains scalable. Optional licences allow activation of up to 80 additional controls. An extension to voice control via ZenVoice is also available. This modular structure enables project-specific adaptation without altering the underlying architecture.
The RemoteBOX is particularly suitable for single-family homes, smaller commercial units or existing installations requiring structured remote access without the need for a fully customised visualisation with an extensive logic engine. For large-scale and complex projects with detailed visualisation concepts, a dedicated visualisation server remains the appropriate solution. The RemoteBOX therefore bridges the gap between a pure KNX project and a comprehensive visualisation system.
Technical integration
The device is designed for DIN rail mounting and occupies 2 modular units. Connection is provided via an Ethernet RJ45 interface with 10/100 Mbit/s. Power is supplied externally with 24–29 VDC. An integrated KNX BCU (TP1) together with support for KNX Data Secure allows integration into existing KNX architectures in line with current security requirements. Ten logic functions are available to implement simple linkages directly within the device.
