Lighting System Upgrade
Lutron HomeWorks Illumination → HomeWorks QSX
115 Chestnut Street, Weston, MA
Prepared for the Glazer Family — March 2026
Executive Summary
Thank you for the opportunity to evaluate your lighting control system at 115 Chestnut Street. After a thorough on-site assessment, we have identified the root cause of the non-working lights and keypads throughout your home, and we are pleased to present our recommended solution.
The Problem
Your central processor (Lutron 8-Series H8P5) has failed. This single component coordinates all communication between wall keypads and lighting panels.
The Good News
Your dimming modules, wiring, and infrastructure are all intact and operational. The issue is isolated to the processor and communication pathway.
The Solution
Upgrade to Lutron HomeWorks QSX — the direct successor platform. Works with your existing wiring, adds modern capabilities.
What We Found
Your home is equipped with a Lutron HomeWorks Illumination system — a premium whole-house lighting control platform that was top-of-the-line when originally installed.
| Component | Details | Status |
|---|---|---|
| Central Processor | Lutron 8-Series (H8P5) with HWI-H48 Interface | Failed |
| Dimming Panels | 2x HWI-PNL-8 with RPM-4A & RPM-4E modules (64 zones) | Working |
| Breaker Panels | 2x HWBP-8D-15-120L3 (8 double-pole 15A breakers each) | Working |
| SeeTouch Keypads | 6-button keypads, bus-wired through LV enclosure | Non-Functional |
| Maestro Dimmers | Wall dimmers throughout home (wiring TBD) | Partial |
| LV Enclosure | HWI-LV32-120 (keypad bus wiring home runs) | Working |
Why a Simple Replacement Is Not Possible
The Lutron HomeWorks Illumination platform has reached end-of-life status. Lutron no longer manufactures the 8-Series processor, replacement units are unavailable, and software support has been discontinued. Lutron has designed a clear upgrade path to their current flagship: HomeWorks QSX.
The Upgrade: HomeWorks QSX
HomeWorks QSX is Lutron's flagship whole-home lighting and shade control platform. It works with your existing wiring infrastructure, minimizing disruption while adding powerful new capabilities.
What Changes
| Component | Current System | New System |
|---|---|---|
| Processor | 8-Series H8P5 (failed) | QSX Processor (HQP7) |
| Communication | RS-485 serial bus | Ethernet IP network |
| Wall Keypads | SeeTouch 6-button (bus) | Palladiom Keypads (HQWT-U-P4W-WH-E) |
| Wall Dimmers | Maestro (wired to H48) | Sunnata Dimmers (HRST-PRO-N-WH) |
| Wall Switches | Maestro (wired to H48) | Sunnata Switches (HRST-8ANS-WH) |
| Dimming Modules | RPM-4A / RPM-4E | DIN Rail Modules + Translators |
| Remote Access | None | Lutron App (phone/tablet) |
| Voice Control | None | Alexa, Google, Apple HomeKit |
What You Gain
Reliable & Redundant
QSX communicates over Ethernet with built-in failover. Faster response times and long-term Lutron support guaranteed.
App Control
Control every light from the Lutron app on your phone or tablet. Set scenes, adjust levels, and check status from anywhere.
Voice Control
Native integration with Alexa, Google Home, and Apple HomeKit. “Set the living room to movie night.”
Palladiom Keypads
Premium Palladiom keypads in architectural white matte with custom engraving. We design button layouts and scene names with you.
Wireless Flexibility
Pico remotes on bedside tables, in media rooms, or anywhere — convenient control without running new wires.
Future-Ready
Supports motorized shades, HVAC integration, and whole-home automation. The system grows with your needs.
What Stays the Same
Existing dimming panels are retained and upgraded in place. All wiring from panels to light fixtures remains unchanged. Keypad locations stay the same — only the devices are swapped. The overall look and feel of your lighting will be familiar, with significant new capabilities added.

Project Timeline
Your Lights Will Not Be Down for 8 Weeks
The majority of this timeline covers off-site preparation: design, ordering, and programming. Your home’s lighting system will only be affected during the on-site installation phase in Week 7 — approximately 3–4 days. Before and after that week, your existing lights function as they do today.
Week 1
Site Survey & Design
Detailed site survey, final device count, keypad engraving design session with homeowner, shade verification. Equipment ordered at end of week — Lutron QSX products typically have 4–6 week lead times.
Weeks 2–6
Equipment Lead Time & Off-Site Programming
While waiting for equipment delivery, QSX database is built in Lutron Designer software. All zones, scenes, and keypad assignments are programmed and tested off-site. No work at your home during this phase.
Week 7
On-Site Installation
3–4 days on-site: panel conversion, processor installation, keypad replacement, dimmer/switch installation. This is the only week your lighting system is affected. Existing wall switches continue working during this phase where possible.
Week 8
Commissioning & Training
Full system commissioning, scene refinement, app setup, and personalized walkthrough for your family. Fine-tuning of lighting levels and scene assignments to your preferences.
Estimated Investment
Based on our initial assessment, the estimated investment for this project falls in the following range. Final pricing will be confirmed after the detailed site survey.
Prices are estimates based on current Lutron pricing. Final pricing confirmed after detailed site survey. Quantities may change based on exact device counts.
Next Steps
If you would like to proceed, the next step is scheduling a detailed site survey. During this visit, we will perform a complete device count, verify lamp types, design your keypad layouts together, and provide a final fixed-price proposal.
