Centralized Lighting Control System Replacement in Houston
LiteTouch, Lutron GRAFIK Eye, Vantage Controls, and Touche are all end-of-life. One Houston LOXONE Partner (since 2015, Platinum today) replaces them — reusing your existing wiring, with admin access and no monthly fees.
Book a free 15-minute callCentralized lighting control systems — LiteTouch, Lutron GRAFIK Eye, Vantage Controls, and Touche — are discontinued and no longer supported. Grizzly Tec replaces them in Houston with LOXONE wired automation, reusing existing low-voltage keypad cable where possible. Clients receive full admin access, the design file, and zero monthly fees.
Do You Have a Centralized Lighting System? 30-Second Check
You probably have one if three or more of these are true in your home or building:
- There's a large metal panel in a mechanical room, utility closet, or basement with rows of labeled circuit cards or plug-in modules.
- Your wall keypads have multiple unlabeled buttons (often 4, 6, or 8) instead of standard rocker switches.
- Keypads run named scenes — Welcome, Goodnight, Movie, Party, Away — not just single lights.
- You can press a single button and lights in multiple rooms change at once.
- Original hardware install was anywhere between 1995 and 2015.
- You have a labeled binder, CD, or USB stick with the original programming somewhere in the house.
If that sounds like your house, you're a candidate for replacement. The next sections name the four systems we replace, what's failing about each, and what the LOXONE path looks like in Houston.
The Four Lighting Control Systems We Replace
Pick your brand for the full replacement walkthrough. Each guide covers parts availability, software status, wiring reuse, and what the cutover looks like.
LiteTouch
DiscontinuedAcquired and shut down. Thousands of Houston homes still running them; parts supply is shrinking every year and keypad failures cascade.
Typical install Homes built 1995–2015
Lutron GRAFIK Eye
End-of-life (all 4 series)Every generation — 3000, 4000, 5000/6000, 7000 — has been sunset. The 5000/6000 programming software requires Windows 98 and cannot run on a modern PC.
Typical install Estates, commercial floors, multi-zone homes
Vantage Controls
Dealer-locked, parts thinningQ-Series and legacy InFusion systems cannot be reprogrammed without an authorized dealer, and replacement modules are increasingly back-ordered.
Typical install Luxury homes, custom estates
Touche
Dissolved April 2026Company dissolved. No manufacturer support, no new parts, no firmware. Common in commercial buildings and high-end residences from the 2000s.
Typical install Commercial buildings, luxury homes

When we finish, we hand you the admin password and the complete configuration file for your system. You have full control. Future changes never depend on us: you can make them yourself, or have any LOXONE partner do it. Already have an electrician you trust? We work alongside them.
Lighting Control Failure-State Matrix
A quick side-by-side of what's actually broken in each platform — so you know how urgent your replacement decision is.
| Brand | Parts | Software | Typical install | Wiring reuse | Urgency |
|---|---|---|---|---|---|
| LiteTouch | Scarce | Limited | Residential | Often reusable | High |
| Lutron GRAFIK Eye | None new | Win 98 only (5000/6000) | Residential + commercial | Often reusable | High |
| Vantage Controls | Thinning | Dealer-only | Luxury residential | Often reusable | Medium |
| Touche | None | Discontinued | Commercial + residential | Often reusable | Critical |
Why Old Lighting Control Systems Get Replaced
- Manufacturer dead-end — discontinued products with no parts, no firmware, no support roadmap
- Programming software no longer runs on modern computers (Windows 98 / dealer-locked tools)
- Original keypad cabling can typically be reused as LOXONE Tree bus — avoiding full re-wiring
- LED retrofits often expose dimmer incompatibilities that the legacy controller cannot resolve
- No remote access, no mobile app, no integration with HVAC, audio, shades, or security
- Dealer lock-in: simple changes require a paid service call instead of self-service
The LOXONE Replacement Path
A typical residential cutover takes 3 to 5 working days. Large estates and commercial buildings phase floor by floor so the building stays operational.
Assessment
We catalog every panel, dimming module, keypad, and circuit. Photograph wiring, check labels, verify what's reusable. Quoted after the free 15-minute call or, for LiteTouch and Vantage, the $450 diagnostic.
LOXONE Config design
We model your home or building in LOXONE Config and produce a channel-for-channel replacement design. The bill of materials matches the runtime configuration exactly.
Cutover & wiring reuse
We remove the legacy panel, install the LOXONE Miniserver and extensions on the same DIN rail or backbox, and reuse existing keypad cable runs where the assessment confirmed they qualify.
Commissioning & handoff
Day-one scenes recreated under their existing names. You receive the LOXONE app, the admin password, the design file, and one year of complimentary support.
What You Get After the Cutover
- Own your system end-to-end — admin password and design file delivered at handoff
- Zero monthly fees, zero subscription unlocks, zero dealer-only changes
- One app for lighting, climate, audio, shading, security, energy, and EV charging
- Local processing on the Miniserver — works even if the internet is down
- Open API for future expansion and third-party integration
- Expandable: add zones, scenes, and adjacent systems as needs evolve

The legacy system Multi-button beige keypads on the wall, a central processor and plug-in dimming modules in the mechanical room. Installed between 1995 and 2015; parts no longer manufactured.
The replacement LOXONE Touch Pure Flex keypads drop into the existing wall openings, and a Miniserver + extensions replace the central panel — typically reusing the original low-voltage cable.
What Does Lighting Control Replacement Cost?
Houston-area replacements typically fall in these ranges:
- Small residential (8–15 zones, 1 panel): $7,000–$25,000
- Large residential (20–40 zones, multi-panel estate): $25,000–$60,000+
- Commercial floor (per-floor migration in a 4–10 story building): from $25,000/floor
- Bundled retrofit (lighting + climate + shades + audio): add 30–60% to the lighting-only number
Reusing existing keypad wiring is the single biggest cost reducer. We assess reuse before quoting.

Houston-Specific: What to Expect
Original integrators who installed LiteTouch and Vantage in the 2000s have either retired or moved on, and the homes are now caught between a system that's failing and a labor pool that's shrunk.
On the commercial side, the GRAFIK Eye 5000/6000 problem is acute — the original programming software was Windows-98-era and most facilities teams can't service the system at all today. Floor-by-floor LOXONE migration during weekend windows keeps operations running.
Texas-side detail: new low-voltage runs may require a separate permit depending on jurisdiction.
Frequently Asked Questions
A centralized lighting control system runs every keypad and dimmer back to a central panel — typically mounted in a mechanical room or closet — that handles all the dimming and scene logic. LiteTouch, Lutron GRAFIK Eye, Vantage Controls, Touche, and older Crestron lighting all use this architecture. It is the opposite of distributed in-wall dimmers (each device wired only to its local fixture), and it is what makes whole-home scene control possible.
Look in your mechanical room, utility closet, or basement for a large metal panel with rows of labeled circuit cards or modules — and look at your wall keypads, which will have multiple unlabeled buttons rather than standard light switches. If your keypads run scenes (Welcome, Goodnight, Movie, Away) instead of just controlling one light, you almost certainly have one of these systems.
All four GRAFIK Eye generations are discontinued. The 3000 series ended in the early-mid 2010s, the 4000 followed, the 5000/6000 reached official End of Life in May 2014, and the 7000 received its hard sunset in December 2024. Lutron no longer supplies parts, technical support, or firmware updates for any of them. The 5000 and 6000 programming software requires Windows 98 and cannot run on a modern PC.
Yes. We've been a LOXONE Partner since 2015 and a Platinum Partner today, serving the greater Houston metro area — including River Oaks, Memorial, The Woodlands, Spring, Cypress, Sugar Land, and Katy — and legacy lighting control replacement is one of our core specialties. Every project starts with a $450 diagnostic, credited toward your project.
In most cases, yes. These systems use low-voltage cable between each keypad and the central panel, and LOXONE's Tree bus typically runs over the same cable. We confirm reuse during the assessment by checking gauge, run length, and termination. When the existing cable cannot be reused, we add new runs only where required — avoiding full re-wiring of the home.
A typical residential cutover takes 3 to 5 working days from hardware removal to a fully commissioned system. Larger estates and commercial buildings are phased floor-by-floor or wing-by-wing so the building stays operational. We schedule around your calendar and coordinate with the licensed electrician (ours or yours) on any high-voltage work.
No. Lighting control replacement swaps the control system — the panel, dimming modules, and keypads — not the fixtures themselves. Your existing recessed lights, chandeliers, sconces, and lamps stay in place. We update fixture drivers only if your current ones are incompatible with modern LED dimming, which is the most common reason older systems start to flicker or fail to dim properly.
Most residential replacements run $15,000–$30,000; the full span is $8,000–$120,000+ depending on system, zone count and scope. Commercial floor-by-floor migrations start around $25,000 per floor. Book a free 15-minute call for any brand; LiteTouch and Vantage projects go through the $450 diagnostic, credited 100% to your project.
Yes. We commission the system so every existing scene name and keypad function is recreated before we hand it over. Day-one familiarity is the explicit goal — you will not need to learn new button positions to run your home. New capability (mobile app, voice, schedules, occupancy) is layered on top as you choose to use it.
Yes. LOXONE installations transfer in full to new owners with no dealer fees, no subscription resets, and no admin lockout — every Grizzly Tec client receives the admin password. Listing agents in River Oaks and Memorial routinely highlight a working, owner-controlled smart home as a differentiator. A failing LiteTouch or GRAFIK Eye system, by contrast, is now showing up as a buyer-side inspection objection.
Yes — especially for commercial buildings and large estates. The most common phased approach replaces the central processor and the highest-traffic floor first, runs that floor on LOXONE while the legacy panel still serves the others, then migrates the remaining floors over weekends.
Both can do the job, but the ownership model is fundamentally different. LOXONE gives you the admin password and the design files on day one; you can change scenes, add devices, and integrate new systems without calling a dealer. HomeWorks QSX requires a certified Lutron dealer for any future programming change and typically carries an annual service plan. For owners who liked that their old LiteTouch or GRAFIK Eye system was theirs to manage, LOXONE is the closer philosophical match.
