C-Bus Repairs & Fault Finding

We troubleshoot the full C-Bus “chain” — power supplies, network health, keypads, dimmers/relays, sensors, interfaces and programming. We aim to restore stability first, then optimise how it runs.

Common repair jobs

• Lights won’t turn on/off or dim properly

• Keypads not responding / dead buttons / LED issues

• Flickering or unstable dimming

• Random dropouts or “some rooms work, others don’t”

• Scenes not triggering, schedules/timers not working

• After-renovation problems (circuits moved, devices replaced)

• Replacing failed dimmers/relays/power supplies

C-Bus Programming & Reprogramming (Changes + Cleanups)

Want changes without ripping everything out? We can:

• Add/rename scenes (e.g., Evening, Entertain, All Off)

• Fix confusing keypad layouts

• Re-map circuits after electrical changes

• Add schedules, timers, and “welcome home” logic

• Document your setup so future changes are easier

Schneider Electric provides C-Bus training/resources for electricians and integrators, and we follow best practice around documenting and maintaining systems. Schneider Electric+1

C-Bus Upgrades (Modern usability without replacing everything)

If you have an older system and want it to feel “current”, we can advise on upgrade paths: replacing tired modules, improving keypad usability, improving reliability, and (where suitable) adding app/automation integrations.

New C-Bus Installations (Renovations + New Builds)

If you’re building or renovating, we can design a C-Bus lighting control layout that scales (circuits, scenes, sensors and keypads), then install and commission it cleanly.

 

Typical C-Bus problems we fix

​

“My C-Bus system is doing weird stuff”

C-Bus is a networked lighting/automation system used to control lighting and other electrical loads in buildings and homes. 
When something is off, it can be hardware, network health, or programming. We’ll isolate the cause and recommend the minimum-change fix.

Examples of symptoms

• Some lights respond, others don’t

• Scenes work sometimes

• A single keypad causes multiple rooms to misbehave

• New LED loads don’t dim smoothly

• System got worse after electrical work

 

How our service works

• Quick triage (phone/photos) – what’s happening, what changed, any patterns

• On-site diagnosis – confirm network health, identify failed devices, check programming state

• Backup + document – protect what you already have

• Repair/replace – fix the root cause (not just symptoms)

• Test + handover – verify scenes/circuits, provide a simple “what we changed” summary
