The Complete Simplification Plan

The whole-home simplification plan.

The Connaughton Residence · 145 Clyde Street, Chestnut Hill, MA

This goes beyond the room-by-room television and Sonos audio refresh on your main plan. It’s the complete path — retiring the entire Crestron and RTI control, the home network, and the whole-home audio & video distribution, replaced by one simpler, more reliable system.

Inside the Rack

What's in your equipment rack today.

A documented inventory of the existing three-bay rack — the cleanup, consolidation, and record-keeping your system has been missing. Identified from a full photographic survey; items still being confirmed are noted.

Control

Two stacked control systems running one home.

RTI XP-8 processor · Crestron 3-Series / Crestron Home processor · RTI cabinet-lock controller · in-wall & handheld touchpanels
RTI · Crestron

Video Distribution

A centralized video matrix routing every source to every TV.

AVPro Edge MXNet (AC-MXNET-1G) transmitters & receivers (~20+) · Apple TV 4K · Comcast/Xfinity cable boxes
MXNet AV-over-IP

Audio

An oversized Sonos system plus distributed-audio amplification.

~34 single-zone Sonos players (over the 32-device limit) · AudioControl Architect amps (~4) · Crestron amplifiers (~4–5)
Sonos · AudioControl

Lighting & Shades

Whole-home lighting and motorized shades on Crestron.

Crestron CLX/CLF lighting power supplies (2 wall enclosures) · lighting & shade load controllers
Crestron Lighting

Networking & Power

The backbone carrying AV, control, and the home network.

Luxul router/switch · L2/L3 PoE+ managed switches · Leviton structured-wiring patch · IP power management & PDUs
Luxul · Leviton

Telecom & Racks

Legacy phone system and the rack housing itself.

Condition & Findings

What's holding the experience back.

The hardware is largely premium and much of it still works. The problems are architectural, not cosmetic.

Two control systems, stacked

RTI and Crestron were layered over time. Two brains controlling one home doubles the failure points and the cost of every future change.

An oversized Sonos system

~34 single-zone Sonos players sit one-per-room — beyond Sonos' 32-device limit, and a textbook cause of the dropouts you experience.

A centralized video matrix

The MXNet AV-over-IP matrix is powerful but the most complex, failure-prone part of the rack — and modern streaming makes most of it unnecessary.

An unsupported cabinet lock

The RTI relay-based lock logic is no longer reliable or supported — a clear candidate for a simple modern relay replacement.

Aging displays & a wall of cable boxes

Multiple TV generations and stacked cable boxes create inconsistent picture quality and HDMI signal instability.

An overcrowded, undocumented rack

Dense cabling and obsolete processors make the rack hard to service and impossible to hand off cleanly — which this assessment begins to fix.

The Decision

Two ways forward.

Both retire the dual-control complexity and the oversized Sonos count. They differ mainly in how lighting, shades, and control are handled.

Path A · Consolidate in place
Standardize on Crestron Home

Keep the Crestron infrastructure — lighting, shades, and amplification — and migrate the whole home onto the modern Crestron Home OS. Retire RTI entirely.

  • Reuses existing Crestron lighting & shade hardware — lowest disruption to the walls.
  • One modern control OS replaces the RTI/Crestron tangle.
  • Single premium app for the whole home.
  • Still a dealer-programmed platform — every change is a truck-roll.
  • Retains the most moving parts, and higher ongoing complexity, long-term.
Path B · Simplify & modernize
Lutron + Sonos + Apple TV RECOMMENDED

Retire RTI and Crestron. Move lighting & shades to Lutron, standardize AV on Sonos audio and Apple TV 4K at every display, all on a dedicated AV network — Josh.ai-ready for natural voice control.

  • Fewest moving parts — the most reliable long-term outcome.
  • Lutron is the gold standard for lighting & shades; serviceable for decades.
  • Apple TV at each TV removes the video matrix and most cable boxes.
  • Sonos consolidated under 32 devices with multi-channel amps — fixes the dropouts.
  • Intuitive, room-based control anyone can use; far less custom programming.

Our recommendation: Path B. It produces the simplest, most reliable home with the lowest long-term support burden — and it aligns with the modernization direction across the rest of your plan (Sony displays, Sonos, Apple TV, dedicated AV network, Josh.ai-ready). Lutron brings the same effortless reliability to lighting and shades. Path A remains a valid lower-disruption alternative if reusing the Crestron lighting investment is the priority.
Scope Direction

What the modernization includes.

Path B at a glance. A detailed room-by-room equipment schedule and pricing are developed in the engineering phase.

Retire legacy control

  • Remove RTI throughout; remove the redundant Crestron control layer.
  • Eliminate the MXNet centralized video matrix.
  • Replace the unsupported cabinet-lock logic with a modern relay solution.

Lighting & shades → Lutron

  • Replace Crestron lighting/shade control with Lutron keypads and load control.
  • Lutron motorized shade control, whole-home, on one reliable platform.

Audio & video → Sonos + Apple TV

  • Consolidate the ~34 single-zone Sonos players with multi-channel amps; back under 32 devices.
  • Evaluate and remove legacy in-wall volume controls.
  • Standardize Sony displays and Apple TV 4K at every TV; Comcast wireless cable where live TV is wanted.

Network, rack & documentation

  • Dedicated AV network/subnet tuned for Sonos and Josh.ai.
  • Remove obsolete hardware and reorganize the rack.
  • Add the home to the Boston Automations homeowner documentation portal.

Ready when you are.

Next step: a field verification visit to confirm the remaining items and capture exact rack positions, followed by the engineering phase — a room-by-room equipment schedule, final audio consolidation plan, and pricing, reviewed with you before any work begins.
