The Complete Guide to Replacing Your LiteTouch System (2026)

LiteTouch lighting systems were discontinued in 2015 and are no longer supported — parts, keypads, and processor boards are increasingly unavailable. The most practical replacement is a modern wired automation platform like LOXONE, which can reuse most existing LiteTouch low-voltage wiring. Here’s everything you need to know about the replacement process, costs, and options.

If you’re reading this, you probably already know something is wrong. A keypad stopped responding. A dimmer flickers. Your installer says the part doesn’t exist anymore. You’re not alone — thousands of homes across Houston and the rest of the country were built with LiteTouch systems, and every one of them is now running on borrowed time.

What Happened to LiteTouch?

LiteTouch was a centralized lighting control system popular in custom homes from the late 1990s through the early 2010s. The system used low-voltage wiring to connect keypads throughout the home to a central control panel, allowing whole-home dimming, scene control, and scheduling from elegant wall stations.

In 2012, Savant Systems acquired LiteTouch. Rather than continuing the product line, Savant absorbed the technology and customer base, positioning its own platform as the upgrade path. By 2015, LiteTouch was fully discontinued — no new hardware, no firmware updates, no replacement parts.

Today, the situation is straightforward: LiteTouch is a dead platform. Existing inventory of replacement parts has dried up. Third-party repair options are limited and unreliable. Every LiteTouch system still running is one component failure away from partial or total loss of lighting control.

This isn’t a scare tactic — it’s the reality we see on service calls every month in the Houston area. The question isn’t whether your LiteTouch system will fail. It’s when.

What Are the Components in a LiteTouch System?

Understanding your LiteTouch system helps you understand what needs to be replaced and what can be preserved. Here are the main components:

Central Control Unit (CCU): The brain of the system. This processor handles all commands from keypads and executes scenes. When the CCU fails, the entire system goes down. Replacement CCUs do not exist.

Dimmer Modules: LiteTouch used several dimmer types — 8-channel, 6-channel, and Quad II modules. These control the actual light output for each circuit. Dimmer modules are the second most common point of failure after keypads.

Relay Modules: For non-dimmable loads like exhaust fans, garbage disposals, or outdoor lighting on simple on/off circuits. These are more robust than dimmers but still age out.

Keypads: The wall-mounted control stations throughout your home. LiteTouch keypads connected via low-voltage wiring back to the central panel. Keypads fail due to age, LED burnout, and internal component degradation. These are typically the first components to fail and the most noticed because they’re the daily touchpoint.

Fan Speed Controllers: Dedicated modules for ceiling fan control. Less common but present in many installations.

Data Input Modules: Used for integration with other systems — security panels, sensors, or timers. These are the least likely to fail but also the least useful once the system is being replaced.

What Fails First?

In our experience across hundreds of LiteTouch service calls in Houston:

1. Keypads — LED backlights die, buttons become unresponsive, communication drops
2. Dimmer modules — Channels stop responding or produce flickering output
3. CCU — When this goes, everything goes
4. Relay modules — Generally the most reliable component

The pattern matters because a single keypad failure is often the first domino. By the time you notice one keypad issue, other components are aging at the same rate.

How Do You Assess Your LiteTouch System Before Replacing It?

Before any replacement project, you need a clear picture of what you’re working with. Here’s what to inventory:

Count your panels and modules. Open your LiteTouch enclosure (usually in a utility closet, garage, or media room) and count the number of dimmer modules, relay modules, and any specialty modules. Each module represents a set of circuits that need to be controlled by the new system.

Count your switches and keypads. Walk the house and count every LiteTouch keypad. Note the number of buttons on each — this tells us how many scenes or zones are controlled from each location. A typical 4,000 sq ft Houston home might have 15-30 keypads.

Identify your wiring type. LiteTouch systems used low-voltage wiring from keypads to the central panel. The two common types are:

• 3-wire (common in older installations): Signal, common, and ground. Works with LOXONE Tree technology in most cases.
• 4-wire (more common in later installations): Adds a power conductor. Ideal for LOXONE Tree — no additional wiring needed.

Check wiring condition. Age, rodent damage, and poor original installation can compromise wiring. During our assessment, we test continuity and insulation on each run. In the vast majority of Houston-area homes we’ve assessed, the wiring is in good condition and fully reusable.

Document your zones and scenes. Note which keypads control which lights and what scenes are programmed. This information guides the new system design and ensures you don’t lose functionality you rely on daily.

If this sounds like a lot, don’t worry — Grizzly Tec handles the entire assessment during a site visit. We document everything and provide a detailed report before any work begins.

What Are Your Replacement Options?

You have several paths forward. Here’s an honest comparison of the leading professional platforms that can replace a LiteTouch system:

Feature	LOXONE	Lutron HomeWorks	Vantage InFusion	Crestron
LiteTouch wiring compatible	Yes (Tree bus)	Yes (designed for it)	Partial	Partial
Homeowner admin access	Full access	Limited	Limited	None
Monthly/recurring fees	None	None	None	Possible
Programming changes	DIY or dealer	Dealer only	Dealer only	Dealer only
Beyond lighting	Full automation	Lighting + shades focused	Lighting + shades	Full automation
Cost range (typical home)	$10K-$40K	$15K-$60K	$15K-$50K	$20K-$70K
Local processing	Yes	Yes	Yes	Yes
Ownership model	You own everything	Dealer-dependent	Dealer-dependent	Dealer-dependent

A note on Lutron HomeWorks: Lutron HomeWorks is a strong platform, and it’s fair to acknowledge that it was specifically designed to accommodate LiteTouch wiring. If your primary concern is lighting control and you want a proven luxury brand with excellent reliability, Lutron HomeWorks is a legitimate option. The tradeoffs are higher cost and dealer dependency for programming changes.

Vantage InFusion offers elegant keypads and good lighting control but is less versatile for whole-home automation and has a smaller dealer network.

Crestron is powerful but complex, expensive, and entirely dealer-dependent. It’s typically overkill for a LiteTouch replacement unless you’re building a commercial-grade media or conference room.

Why Is LOXONE the Best LiteTouch Replacement?

We install LOXONE — so take this section with appropriate context. That said, here’s why we chose LOXONE as our platform after evaluating every major option:

Tree bus technology reuses LiteTouch wiring. LOXONE’s Tree bus communication protocol runs on the same low-voltage wiring that LiteTouch systems use. In most homes, we connect LOXONE Tree devices to existing wire runs without pulling a single new cable. This dramatically reduces installation time and cost.

Full ownership with admin access. When we hand over your LOXONE system, you get the admin password. Period. You can open LOXONE Config and make changes yourself — rename rooms, adjust scenes, add schedules. You can also hire any LOXONE partner to service your system. There is no dealer lock-in.

It goes far beyond lighting. LiteTouch was a lighting system. LOXONE is a full automation platform. From day one, your lighting replacement can also control:

• Climate (thermostats, zone dampers, humidity)
• Audio (multi-room music, intercom, doorbell integration)
• Motorized shades and blinds
• Security sensors and cameras
• Access control (smart locks, gate controllers)
• Pool and spa equipment
• Irrigation

You don’t have to add all of this on day one — but the infrastructure is there when you’re ready.

No monthly fees. Ever. LOXONE core automation runs locally on the Miniserver in your home. There is no cloud subscription, no recurring license, no “premium tier” to unlock features. You buy the system, you own the system.

Over 300,000 active installations worldwide. LOXONE is not a startup or a niche product. It’s a mature platform with active R&D, annual product releases, and a growing global network of certified partners. Grizzly Tec is a LOXONE Gold Partner serving the greater Houston area.

What Does the Replacement Process Look Like?

We’ve refined the LiteTouch-to-LOXONE process over hundreds of projects. Here’s what to expect:

Step 1: Assessment (1-2 hours on-site)

We visit your home, open the LiteTouch panel, and document every module, circuit, keypad, and wire run. We test wiring condition and identify any areas that may need new cable. You walk us through your daily routines so we understand which scenes and controls matter most.

Step 2: Design (1-2 weeks)

We create a detailed system design — what LOXONE hardware is needed, where new keypads or touch panels will go, and how the system will be programmed. You receive a proposal with itemized costs, a timeline, and a clear scope of work.

Step 3: Install (3-5 days typical)

We remove the LiteTouch equipment from the central panel and install LOXONE Miniserver, Tree Extensions, dimmers, and relay modules. At each keypad location, we replace the LiteTouch keypad with a LOXONE Touch or LOXONE Keypad. We phase the work room by room so you’re never without lighting in the whole house simultaneously.

Step 4: Program & Commission (1-2 days)

With hardware installed, we program scenes, schedules, and integrations. We test every circuit, every keypad button, and every scene. We verify dimming curves work correctly with your specific fixtures and bulbs.

Step 5: Train & Handoff

We sit down with you and walk through the LOXONE app — how to control your home, how to adjust scenes, how to use scheduling. We hand over the admin credentials and make sure you’re comfortable. Our support doesn’t end at handoff — Grizzly Care plans are available for ongoing assistance, but they’re optional, not required.

Typical timeline from first call to completion: 4-8 weeks, with 3-5 days of on-site work for an average-sized home. Larger estates or whole-home automation projects may take 1-2 weeks of on-site work.

How Much Does It Cost to Replace a LiteTouch System?

This is the question everyone asks first, and the honest answer is: it depends on your home. But here are the factors and ranges to help you plan.

Cost Factors

Number of lighting circuits. More circuits mean more LOXONE dimmer channels. A home with 30 circuits is different from one with 120.

Number of keypad locations. Each LiteTouch keypad location gets a LOXONE replacement. LOXONE offers keypads at different price points — from simple rockers to full-color touch panels.

Wiring condition and compatibility. If your existing LiteTouch wiring is in good condition (and it usually is), the cost is lower. If sections need new cable, that adds labor.

Scope beyond lighting. Replacing LiteTouch with LOXONE for lighting only is the baseline. Adding climate, audio, shading, or security increases the project scope and cost.

Home size and complexity. A 3,000 sq ft home with 25 circuits and 15 keypads is a different project than a 10,000 sq ft estate with 80 circuits, motorized shades, and a pool.

Typical Ranges

• Lighting-focused replacement (smaller home, 20-30 circuits): $7,000 - $15,000
• Mid-range replacement (average home, 30-60 circuits, some extras): $15,000 - $30,000
• Whole-home automation (large home, 60+ circuits, audio, shades, climate): $30,000 - $60,000+

Important: Hardware is one part of the equation. Professional installation and programming typically adds 40-60% on top of equipment cost. This covers labor, electrical work, programming, commissioning, and training. Any quote that lists only hardware cost is leaving out the majority of the project.

Making the Decision

If your LiteTouch system is still running, you have a window to plan a controlled migration on your schedule — rather than scrambling when a critical component fails. The replacement parts market will only get worse from here.

We’ve helped hundreds of Houston-area homeowners move from LiteTouch to LOXONE. The most common reaction after the transition: “I wish I’d done this sooner.”

Here’s what we recommend:

1. Book a free assessment. We’ll evaluate your system and give you a clear picture of its condition and your options.
2. Get a detailed proposal. No pressure, no obligation. You’ll know exactly what the project involves and what it costs.
3. Decide on your timeline. Some clients move forward immediately; others plan for a few months out. Either way, you’ll have a plan.
