A Hawaii residence asks the same questions of a Crestron and Lutron system as a mainland estate — control, lighting, shading, networking, security — but the island environment changes where equipment can live, which hardware classes hold up outdoors, and how procurement has to be sequenced. These are design questions worth resolving before a rack room is framed or a shade order is placed, not after.
Where the control equipment actually lives
Crestron's own automation enclosures, the CAEN series used to house CLX lighting modules and 4-Series DIN processors, are rated for 10% to 90% relative humidity, non-condensing, and an operating temperature range of 32°F to 104°F (CAEN-2X1). The DIN-AP4 processor carries a similar humidity spec of 10% to 90% RH, non-condensing, with a tighter temperature window of 41°F to 113°F (DIN-AP4). Non-condensing is the operative phrase for Hawaii: a closet or equipment room on an exterior wall, or any space without reliable dehumidification, can see condensation swings that these ratings don't cover. That's a reason to ask your contractor where the rack room sits relative to exterior walls, and whether the space has independent climate control rather than relying on whatever HVAC zone happens to reach it.
This matters more on an island property than it would in a climate-controlled Northeast basement, because a rack room that drifts outside the non-condensing range on a humid night is a rack room that can start throwing faults long before anyone notices a leak. Ask about a dedicated mini-split or dehumidifier for the equipment space as part of the mechanical plan, not an afterthought.
Lighting and shading control: Lutron inside Crestron Home
Cave Group designs around Crestron for whole-home control paired with Lutron for lighting and shades, and the two platforms are built to integrate rather than compete. Lutron HomeWorks QSX, RadioRA 3, RA2 Select, and HomeWorks QS processors all pair natively into a Crestron Home system, and HomeWorks QSX specifically adds support for Ketra tunable-white loads alongside standard switched and dimming circuits (Pair and Configure a Lutron System with a Crestron Home System). For shading, Crestron Home documentation lists both Crestron's own QMT-series shade motors and Lutron shade hardware as supported devices, with Lutron shades excluded from Crestron's own shade groups — Lutron shade groups are set up in Lutron's own Designer software instead (Shading | Crestron Home OS Documentation). That division of labor is worth settling at the design stage: which rooms get Crestron-native shade control, which get Lutron, and how scenes that span both are built, since the two don't merge into a single shade-group list automatically.
A homeowner building or renovating in Wailea, Kahala, or along the Kohala Coast should ask specifically how indoor-outdoor rooms — lanais, pool pavilions, covered terraces that are functionally part of the living space — get assigned between the two platforms, since humidity and salt exposure differ sharply between an interior room and a covered but open-air one.
Networking hardware built for outdoor, salt-exposed mounting
Island properties lean more heavily on outdoor Wi-Fi coverage than a typical mainland estate — pools, lanais, docks, and detached structures all need signal, and that pushes access-point selection toward hardware rated for the exposure. Ubiquiti's outdoor UniFi access-point line includes models built to an IP67 weatherproofing rating in a rugged metal enclosure, such as the U7 Industrial and U7 Pro Outdoor, versus the lighter IPX6 rating on some mesh-oriented outdoor models (UniFi Outdoor WiFi Access Points). IP67 and IPX6 are not interchangeable specs — IP67 covers temporary submersion, IPX6 covers powerful water jets but not submersion — and that distinction is worth raising explicitly when choosing hardware for a covered lanai versus a fully exposed pergola or dock mount.

Sequencing procurement against shipping, not a truck route
A mainland project can often swap a shade motor or add an access point within a week of discovering a gap. On an island, ordering runs through ocean freight, and lead time has to be built into the schedule rather than treated as a buffer. That means finalizing shade motor counts, keypad models, and network hardware models earlier in the design process than a comparable mainland project would, since a mid-construction change order carries a shipping delay on top of the usual lag. Worth asking any contractor bidding island work: what their standard order-to-site timeline looks like for Crestron, Lutron, and networking hardware, and whether they stage spares on-site for components most likely to need field replacement.
Questions to settle before rough-in
A few decisions are worth locking before conduit and low-voltage wiring are set: where the equipment room sits and how it's climate-controlled independent of general HVAC; which rooms route lighting and shade control through Lutron versus native Crestron shade hardware; which access points need IP67-class outdoor ratings versus a lighter indoor-rated unit in a covered space; and how far in advance of construction milestones hardware needs to be ordered to clear ocean freight. Cave Group designs residential systems around Crestron for control and Lutron for lighting and shading, and pairs that with UniFi networking sized to the property — a framework that holds whether the house sits on Long Island or on Maui.
