Sound familiar?

Smart home systems are brilliant when they work — and incredibly frustrating when they don't. You've probably tried turning things off and on, pressed every button on the keypad, and you're still stuck. You're not alone.

Lights won't respond to keypads or the app

You press a scene button and nothing happens — or only some lights come on. Lutron keypads may flash but fail to trigger, Crestron touchscreens show 'offline,' or your Control4 app just spins.

Heating or cooling has stopped following its schedule

Your smart thermostat or HVAC integration has lost its programming. The house is too hot, too cold, or the system is stuck in a mode you can't override from the panel or app.

Blinds or curtains won't open or close

Motorised blinds have frozen mid-position, won't respond to wall switches, or have lost their calibration limits. Common across Lutron Sivoia, Crestron Shading, and Control4-integrated motors.

Touchscreens or remotes are unresponsive

Your Crestron TSR-310 remote shows a black screen, the Control4 Halo remote is stuck on 'Waiting for Network,' or your in-wall touchpanels have gone completely blank.

AV system won't turn on or switch inputs

You can't watch television because the automation won't power up the right devices, switch to the correct HDMI input, or control the volume. Everything requires manual intervention.

You've tried rebooting and it hasn't helped

You've power-cycled the processor, restarted the router, and nothing's changed. The system needs someone who can access the programming, check device communication, and trace the actual fault.

How We Fix It

A clear, structured process that gets your smart home back to normal — usually within a single visit.

1

Tell Us What's Happening

Describe the symptoms — what's not working, when it started, and whether anything changed (power cut, router swap, building work). We'll identify the likely cause before we arrive.

2

Remote Diagnosis

Where possible, we connect remotely to your Crestron, Lutron, or Control4 processor to check system logs, device status, and network health. Many issues can be identified — and sometimes resolved — without a site visit.

3

On-Site Repair

If a visit is needed, our engineer inspects the AV rack, network infrastructure, and control hardware. We test every subsystem — lighting, HVAC, shading, AV — and resolve faults on the spot.

4

Test, Handover & Protect

We walk you through everything that was fixed, test all scenes and automations with you present, and recommend a maintenance plan to prevent future issues.

“Our entire Crestron system went down on a Friday evening — no lights, no heating control, nothing. They came out the next morning, found a failed network switch in the rack, replaced it, and had everything running by lunchtime. Absolutely brilliant service.”

James P. Surrey

“We'd been living with a half-working Control4 system for months because our original installer kept fobbing us off. These guys came in, diagnosed three separate faults in under an hour, and fixed the lot. Should have called them first.”

Helen M. Cheshire

“Our Lutron lighting had been playing up for weeks — random scenes triggering, keypads unresponsive. They remoted in the same afternoon we called, identified a firmware conflict, and had it sorted by the following morning. Really impressed.”

David & Claire R. North London

Frequently Asked Questions

We specialise in the three major professional platforms: Crestron, Lutron, and Control4. These cover the vast majority of professionally installed smart homes in the UK. We also work with systems that integrate with these platforms, including Sonos, Lutron Sivoia shading, and third-party HVAC controls.

Absolutely. The majority of our repair work is on systems installed by other companies. We're fully certified across all three platforms and can access, diagnose, and reprogram any Crestron, Lutron, or Control4 system regardless of who originally installed it.

We offer same-day response for urgent issues. For non-emergency faults, we typically schedule a remote diagnosis within 24 hours and an on-site visit within 48 hours. If your heating, security, or access control is affected, we treat it as a priority.

In many cases, yes. Crestron, Lutron, and Control4 processors can all be accessed remotely if your network is functioning. We can check system logs, device communication status, and firmware versions without visiting. If the network itself is the issue, we'll need to attend site.

We provide a clear quote before any work begins. A standard diagnostic visit typically takes two to three hours. We don't charge for the initial phone consultation, and if we can resolve the issue remotely, you'll only pay for the remote support time.

We regularly work on older Crestron 2-Series and 3-Series processors, Lutron HomeWorks QS, and legacy Control4 HC-series controllers. If parts are no longer available, we'll advise on the most cost-effective upgrade path rather than replacing your entire system.

Yes. We offer maintenance contracts that include proactive remote monitoring, priority response times, and scheduled health checks. Many clients move to a support plan after their first repair to avoid future disruption. It's significantly cheaper than paying per callout.
