Smart buildings are no longer judged solely by how many functions they automate—they are judged by how visible, manageable, and resilient those functions are over time. As KNX installations expand across residential, commercial, and mixed-use environments, the need for reliable remote monitoring has become mission-critical.
The Jigsaw KNX Gateway (2 Users) is purpose-built to provide this visibility layer. Acting as a secure KNX/IP interface, it allows authorised stakeholders to monitor system activity, perform remote diagnostics, and maintain control without constant on-site intervention. For many small to medium KNX deployments, it represents the ideal balance between capability, simplicity, and cost.
In this extended guide, we will take a deep technical and practical look at how the Jigsaw KNX Gateway (2 Users) supports system monitoring, what makes it effective, where it fits best, and how to deploy it for maximum long-term value.
What Is the Jigsaw KNX Gateway (2 Users)?
The Jigsaw KNX Gateway (2 Users) is a KNX/IP tunnelling interface that connects a KNX twisted pair (TP) bus to an Ethernet network. Its primary purpose is to allow remote software tools—such as ETS and visualisation platforms—to communicate with the KNX installation over IP.
The “2 Users” specification indicates the device supports two simultaneous tunnelling connections, which is ideal for scenarios where:
- One user is the building owner or facility manager
- One user is the system integrator or support engineer
This focused design keeps the device efficient and cost-effective while still delivering professional-grade monitoring capabilities.
Key Roles in a KNX System
The gateway typically serves as:
- Remote programming interface
- Bus monitoring point
- Diagnostic access node
- Integration bridge to IT networks
- Support tool for maintenance teams
Because KNX systems are highly decentralised, having a reliable IP gateway dramatically improves operational visibility.

The Growing Importance of KNX System Monitoring
KNX installations are known for stability, but modern buildings demand continuous performance assurance, not just basic functionality.
Challenges Without Proper Monitoring
In unmanaged KNX environments, common pain points include:
- Faults going unnoticed for long periods
- Slow response to device failures
- Expensive and unnecessary site visits
- Difficulty verifying user complaints
- Limited energy performance insight
- Reduced confidence in the automation system
The Jigsaw KNX Gateway (2 Users) directly addresses these issues by enabling real-time remote visibility.
Operational Benefits of Monitoring
With proper gateway deployment, building operators gain:
- Faster troubleshooting
- Proactive maintenance capability
- Improved occupant satisfaction
- Lower service costs
- Better energy optimisation
- Enhanced system transparency
Core Functions of the Jigsaw KNX Gateway (2 Users)
The gateway delivers several essential capabilities that make KNX systems easier to manage.
KNX/IP Tunnelling Interface
This is the primary function. The device converts KNX telegrams into IP packets and vice versa, allowing ETS and other tools to communicate with the KNX bus remotely.
Passive Bus Monitoring
The gateway can observe bus traffic without interfering with normal operations. This is extremely valuable during commissioning and troubleshooting.
Remote Programming Support
Integrators can download applications, modify parameters, and perform diagnostics without physically connecting to the bus.
Controlled Multi-User Access
Supporting two concurrent sessions allows collaboration while maintaining predictable performance.

How the Gateway Works in Practice
Understanding the real-world data flow helps clarify why the Jigsaw KNX Gateway (2 Users) is so useful.
Step-by-Step Communication Flow
- KNX devices exchange telegrams on the TP bus
- The gateway listens to bus traffic
- Telegrams are encapsulated into IP format
- Remote client connects via tunnelling
- Software decodes and displays data
- Commands from ETS or monitoring tools are sent back via the gateway
Importantly, the gateway operates transparently—it does not become a single point of control but rather an access window into the KNX system.
Real-Time Monitoring Capabilities
One of the strongest advantages of the Jigsaw KNX Gateway (2 Users) is the depth of monitoring it enables.
Live Telegram Analysis
Integrators can view bus traffic in real time to:
- Detect communication errors
- Identify telegram flooding
- Verify device responses
- Troubleshoot intermittent faults
This significantly reduces diagnostic time.
Group Object Monitoring
Users can observe the live state of KNX group addresses, including:
- Lighting commands
- HVAC setpoints
- Blind positions
- Sensor values
- Energy data
This visibility is invaluable for both commissioning and ongoing support.
Remote Fault Investigation
Many support tickets can be resolved remotely once the gateway is in place, eliminating unnecessary truck rolls.

Benefits of the Two-User Limitation
At first glance, two users may sound restrictive—but in practice, it is often ideal.
Designed for Real-World Usage
Most KNX projects only require:
- One operator
- One integrator
The Jigsaw KNX Gateway (2 Users) matches this common need precisely.
Performance Stability
By limiting concurrent sessions, the gateway maintains:
- Low latency
- Stable tunnelling
- Predictable bandwidth usage
- Reduced CPU overhead
Cost Optimisation
Compared to large KNX servers, the two-user model offers:
- Lower hardware cost
- Simpler configuration
- Reduced IT overhead
For many projects, this is the sweet spot.
Security and Remote Access Best Practices
Because the gateway exposes KNX data to IP networks, cybersecurity must be carefully considered.
Built-In Security Features
Typical deployments support:
- Password authentication
- Session control
- ETS Secure compatibility
- Network-level protection
- VPN interoperability
Recommended Deployment Strategy
For production environments:
- Place the gateway behind a firewall
- Use VPN for remote access
- Avoid public port forwarding
- Change default credentials
- Segment OT and IT networks
- Monitor access logs
Security misconfiguration is one of the few real risks in KNX/IP deployments, so careful setup is essential.

Integration with ETS Engineering Tool
ETS connectivity is one of the primary reasons integrators deploy the Jigsaw KNX Gateway (2 Users).
Advantages for Integrators
Using ETS over IP allows:
- Remote commissioning
- Faster troubleshooting
- Reduced travel time
- Easier firmware updates
- More efficient support contracts
Remote Commissioning Workflow
A typical workflow:
- Integrator connects via VPN
- ETS discovers the gateway
- Tunnelling session is established
- Devices are programmed or monitored
- Changes are verified in real time
This dramatically improves service efficiency.
Visualisation and Building Management Integration
Beyond ETS, the gateway plays a key role in system visualisation.
Supported Monitoring Platforms
The Jigsaw KNX Gateway (2 Users) can feed data into:
- KNX visualisation software
- Smart home dashboards
- Facility management systems
- Energy monitoring tools
- Custom middleware platforms
Benefits for Building Owners
Operators gain:
- Centralised system visibility
- Real-time feedback
- Better comfort control
- Improved energy awareness
- Faster fault detection
This transforms KNX from a “set and forget” system into a continuously optimised platform.

Installation and Network Planning Best Practices
Proper deployment is critical to long-term success.
Physical Installation Tips
- Mount in a well-ventilated control cabinet
- Keep close to main KNX line where practical
- Use reliable power supply
