Legacy & inherited systems
The system you inherited, made dependable again.
Plenty of fine Sydney homes run on C-Bus, Dynalite, KNX or an HPM Oscar iControl panel that nobody services any more. We assess what is there, get it working, and only then talk about replacing it.
The idea
Assess first. Rip out last.
An older lighting or automation system is usually salvageable in part. Field wiring, dimmer racks and switch plates often stay; the brain and the interfaces are what date.
We document what exists, tell you plainly what is worth keeping, and stage the work so the house keeps functioning throughout.
Repair & support
Faults traced, not guessed.
Most legacy call-outs are a failed dimmer channel, a lost program file or a dead panel, all findable with the right tools and records.
- Clipsal C-Bus, network faults, dimmer failures, missing project files, key programming.
- Dynalite, controller and ballast faults, scene levels reset properly.
- KNX, bus diagnostics and re-commissioning of existing devices.
- HPM Oscar iControl, replacement paths for panels no longer supported.

Upgrade paths
Keep the wiring. Change the intelligence.
Where an old platform is genuinely past it, the existing cabling usually lets us modernise without opening walls.
- Bridge C-Bus, Dynalite or KNX into Control4 so one interface runs everything.
- Or replace the control layer entirely and reuse existing lighting circuits.
- New engraved keypads in place of dated plates, room by room.
- Staged over weeks, with the house lit and usable every night.

In detail
What an assessment covers
01
Site audit
Every panel, controller and circuit identified and photographed.
02
Documentation
A record of the system as it exists, often the first one the home has had.
03
Options
Repair, bridge or replace, with the trade-offs written down.
04
Handover
Programming files and documentation left with you, not held hostage.
Questions
What homeowners ask us
- Our C-Bus, Dynalite or KNX system is failing. Do we have to replace it?
- Not necessarily. We first assess what is installed, identify the faults and get the system working. Replacement is discussed only once it is stable and you can weigh the options.
- Can an older lighting system be controlled by Control4?
- Often, yes. Many C-Bus, Dynalite and KNX installations can be integrated so Control4 provides the interface while the existing lighting hardware keeps working, allowing a staged upgrade.
- There is no documentation for our system. Is that a problem?
- It is common in inherited homes. Part of the work is surveying the system, recording what each circuit and device does and leaving you with documentation and a backup.
