Smart Lighting for New Builds: C-Bus vs DALI vs KNX vs Wireless
Wired systems (C-Bus, KNX and DALI) are the most reliable choice for new builds and large homes, because control runs on its own cabling and doesn't depend on Wi-Fi. Wireless smart switches and platforms such as Clipsal Wiser or Matter-compatible devices cost less and suit renovations and smaller homes. Choose before frame stage, because wired systems need their own cabling.
What smart lighting actually means
Smart lighting isn't just lights you can turn on from your phone. A proper smart lighting system gives you:
- Scenes: one button sets several lights to preset levels for cooking, dinner, movies or bedtime
- Schedules: garden, facade and security lights that follow sunset through the year
- Sensors: lights that respond to people moving through hallways, stairs and robes
- Central control: "all off" as you leave, holiday mode while you're away, and app or voice control
- Integration: lighting that works with blinds, climate, security and audio-visual systems
How reliably it does those things depends on the system underneath.
The options at a glance
| System | Wired or wireless | Open standard or brand | Relative cost | Best for | Plan at frame stage? |
|---|---|---|---|---|---|
| C-Bus | Wired (wireless option) | Clipsal by Schneider Electric | Medium to high | New builds and larger homes in Australia | Yes |
| KNX | Wired (wireless options) | Open international standard | Medium to high | High-end homes wanting wide hardware choice | Yes |
| DALI | Wired control line | Open standard (IEC 62386) | Medium to high | Precise dimming, tunable white, commercial and high-end homes | Yes |
| Integration platforms (Control4, Savant) | Mostly sit on top of a lighting system | Brand ecosystems | High | Homes wanting lighting, AV, security and climate in one interface | Yes |
| Wireless smart switches (Clipsal Wiser and others) | Wireless | Brand, some Matter-compatible | Low to medium | Renovations and smaller homes | Helpful |
| Smart globes (Hue-style) | Wireless | Brand, some Matter-compatible | Low | Lamps and a few rooms | No |
C-Bus
C-Bus is Clipsal's wired control system, used in Australian homes for decades. Keypads and sensors talk over a dedicated data cable to dimmers and relays in the switchboard. It's familiar to many Australian electricians, reliable, and integrates with blinds, fans, security and AV. We explain it in detail in What is C-Bus?
KNX
KNX is an open international standard for home and building control, supported by hundreds of manufacturers. That gives more choice of keypads, sensors and modules than a single-brand system, and it's especially strong in Europe. It needs its own bus cable and an integrator experienced in programming it.
DALI
DALI (Digital Addressable Lighting Interface) is an open standard, IEC 62386, focused on lighting. Each driver or fitting has its own address on a two-wire control line, with up to 64 devices per line. That means every light can be dimmed, grouped and scheduled individually, and it's excellent for smooth dimming and tunable white (lighting that shifts colour temperature through the day). DALI is widely used in commercial buildings and increasingly in high-end homes, often alongside another system for keypads and integration.
Integration platforms: Control4 and Savant
Platforms such as Control4 and Savant tie lighting, audio-visual, security, climate and more into one app and remote. They usually sit on top of a lighting control system rather than replacing it, so you'd still choose how the lighting itself is switched and dimmed.

Wireless smart switches and Matter
Wireless smart switches replace ordinary switches and talk to each other and a hub over a wireless network. Clipsal Wiser is a common Australian example. Many newer products support Matter, an industry standard designed to make devices from different brands work together.
Wireless is cheaper and far easier to retrofit, because there's no new data cabling. The trade-off is that reliability depends on the wireless network and the hub. For renovations and smaller homes, it's usually the practical choice. It still helps to plan neutral wiring, switch box depth and network coverage at rough-in.
What does home automation cost?
The range is wide: from a few hundred dollars for a handful of wireless smart switches to tens of thousands for a fully wired, integrated system in a large home. The main cost drivers are:
- the number of lighting circuits and how many are dimmed
- the number of keypads, touchscreens and sensors
- integration with blinds, climate, security and AV
- programming time and scene set-up
- new build versus retrofit
The most useful comparison is your own lighting plan priced two or three ways.
How to choose
Work through these questions in order:
- Is it a new build or major renovation with open walls? If yes, a wired system is worth pricing. If no, start with wireless.
- How many lighting circuits? More circuits and larger homes favour wired control.
- Do you want integration with blinds, security, climate or AV? If yes, consider a wired system plus an integration platform.
- Is precise dimming or tunable white a priority? If yes, consider DALI for those areas.
- How long will you stay? Long-term owners get more value from a wired system's reliability.
Whichever way you go, the control decision has to be made before rough-in. Our checklist of decisions to lock in before frame stage explains the timing. We design and install smart lighting through our smart LED lighting and automation service, including in Kawana Waters, and for businesses through our commercial LED lighting work.
Frequently asked questions
What is the best home automation system in Australia?
There isn't one best system. C-Bus and KNX are proven wired systems for new builds and larger homes; DALI gives the finest lighting control; wireless systems like Clipsal Wiser suit renovations and smaller budgets. The right choice depends on the home, the budget and how much integration you want.
What is DALI lighting?
DALI (Digital Addressable Lighting Interface) is an open standard, IEC 62386, for controlling lights. Each fitting or driver has its own address on a two-wire control line, so lights can be dimmed, grouped and scheduled individually. It's widely used in commercial buildings and high-end homes.
How much does it cost to automate a home?
It ranges widely, from a few hundred dollars for some wireless smart switches to tens of thousands for a fully wired, integrated system in a large home. The main cost drivers are the number of lighting circuits, keypads, dimmers, integration and programming.
Is wired or wireless smart lighting better?
Wired systems are more reliable and fast because control runs on dedicated cabling, and they don't depend on your Wi-Fi. Wireless is cheaper and easier to retrofit. For a new build, wired control is worth considering; for renovations, wireless is usually the practical choice.
What's the difference between KNX and C-Bus?
Both are wired building control systems. KNX is an open international standard with hundreds of manufacturers; C-Bus is a Clipsal product range with a long history in Australia. KNX offers more hardware choice; C-Bus is widely known by Australian electricians.
