KNX smart homes are a global standard in home automation systems – with a decentralised system that communicates over multiple mediums, including twisted-pair cables, powerline, radio frequency, and IP/Ethernet.

KNX creates homes that follow your lead; from adjusting the temperature to your preferences, to playing your favourite songs and syncing your home’s lighting scheme to your circadian rhythm.

Here at Crown Electrical Solutions we are KNX Dealer in Australia can help you navigate everything from KNX lighting control to KNX security systems. We have significant experience creating tailored smart homes and can design a customised KNX system for a more connected life.

What is a KNX smart home?

KNX stands for connects. And that’s the core of it – a KNX home is a connected home.

From heating to lighting, across multiple systems, different devices and throughout your property, a KNX automation system links together to create a robust and scalable smart home solution.

How does KNX home automation work?

KNX automation operates through a decentralised system, connecting various devices and controls under a single communication protocol.

Here’s how it works:

1. Decentralised Communication

KNX uses a bus system, a dedicated green cable that connects devices independently of the home’s electrical wiring. Each device, whether it’s a sensor or actuator, communicates via the KNX protocol, enabling seamless interaction across the network .

2. Device Integration

KNX supports a wide range of devices from different manufacturers, ensuring interoperability. This means components like HVAC systems, blinds, security and KNX lighting control systems can work together efficiently, regardless of the brand .

3. Custom Programming

During installation, devices are programmed using the ETS (Engineering Tool Software). This software assigns specific functions to each device, such as triggering lights based on motion or adjusting blinds based on sunlight intensity. These configurations ensure tailored automation for the user’s needs.

4. Flexible Control Options

Users control KNX through wall-mounted keypads, touchscreens, smartphone apps and voice assistants. This variability makes KNX one of the more user-friendly smart home systems, even for non-technical minded individuals .

5. Scalability and Future-Proofing

KNX systems are designed to be expandable. Homeowners can easily add new devices or upgrade functionality over time without overhauling the existing setup. This adaptability ensures the system evolves with both its users, and changing technology.

What’s the difference between KNX and other home automation systems?

KNX is a powerful and complex system that is generally considered ideal for multi-dwelling properties, and homes with complex automation needs. Other smart home systems often offer less advanced functionality or interoperability.

KNX is also an open standard, meaning it is not owned or controlled by any one company, and KNX-compatible products can be purchased from various manufacturers and integrated into one system.

Other home automation systems are more exclusive, meaning only partner products can be used. An open standard provides more flexibility and lower costs, as well as scalability.

Installing KNX devices in your home

KNX installation requires skill, experience and precision. At Crown Electrical Solutions, our expert technicians can ensure your system is configured for your requirements – and that you receive the training to get the most out of it.

This is done in four stages :

1. Consultation

KNX installations are as unique as their users. The first step is understanding how you live, and how you plan to use your smart home. This way, your consultant can design a tailored system that matches your lifestyle.

2. Installation

This stage involves meticulous attention to detail. Our technicians are trained to handle the installation of all KNX hardware and software, ensuring each component is correctly positioned. Our professional installation guarantees an efficient setup, minimising disruptions to your home life.

3. Integration

A KNX installation wouldn’t be complete without seamless integration. At Crown Electrical Solutions, we pride ourselves on ensuring your system is working as cohesively as possible. This means testing, testing, and more testing, until we’re satisfied that the entire system is communicating effectively.

4. Training

At Crown Electrical Solutions, our service goes beyond installation. We’ll provide you with the information and tools you need to efficiently manage your new smart home.

We provide a full training session to familiarise yourself with the interface and functionality of your KNX system.

Our experts will walk you through everything from scheduling to creating specific scenes so that you can confidently control your home.

FAQ’s

1. What devices can KNX control?

KNX systems are capable of controlling lighting, heating, ventilation and air conditioning, as well as security – you can automate KNX to lock windows, monitor motion detectors and fire alarms, activate security lighting and alert residents.

Because KNX’s advanced capabilities can link multiple devices together, the possibilities for home automation are endless. Beyond lighting and heating, you can automate intercom systems for two-way communication, motor controls for curtains, blinds and garage doors, pool and spa controls, irrigation for automated lawn watering, and more.

KNX home automation system sensors are also capable of detecting environmental changes and conditions in the building – changes like temperature, humidity, light levels, and motion. The sensors transmit this data over the KNX bus so the system can adjust settings to optimise comfort and energy efficiency.

2. What are the benefits of a KNX system?

– Flexibility and Interoperability :

Unlike other, more exclusive smart home systems, KNX is an open protocol. This design allows the use of devices from numerous manufacturers, which ensures a high degree of customisation, enabling users to expand their systems over time without being locked into a single brand.

KNX can integrate with other brand solutions such as Control4 Home Automation, CBus and Crestron.

– Reliability and Scalability :

KNX uses a decentralised architecture, meaning each device can operate independently. This hardy design means the system remains functional even if one component fails. It is also highly scalable, making it ideal for both small homes and complex, multi-building installations.

– Energy Efficiency :

Because KNX smart homes ensure devices only operate when needed (based on occupancy, fluctuating temperatures, and your personal preferences), a KNX system can reduce your home’s energy usage by up to 30% annually.

3. How much does a KNX system cost?

The cost of your KNX system depends largely on the scale and complexity of your project.

Small homes or apartments with more basic automation features (like lighting and blinds) can run from as little as $10,000 to $20,000. This includes essential components, wiring, and installation services.

Larger homes with more advanced features (like integrated HVAC, security systems, and energy management) can range from $40,000 to $100,000, or more. The scale of integration and the number of devices significantly impacts overall price.

Price is also influenced by whether your KNX system is being installed in a new build, or retrofitted to an existing building. Installation in an existing home can increase costs due to the need for wireless components or additional modifications.

4. Is KNX worth it?

KNX home automation is worth considering if you prioritise a highly customisable and scalable system, particularly for larger homes or complex projects. KNX allows seamless integration of devices from multiple manufacturers, and excels in energy efficiency by optimising heating, cooling, and lighting, potentially lowering energy bills over time.

The high upfront cost may make it less appealing for smaller homes or those seeking a simpler, plug-and-play solution, but for households with significant automation needs, KNX offers exceptional value and long-term benefits.

Crown Electrical Solutions can help you decide if a KNX system is for you.
