Avoca Beach is one of the Central Coast's premium beachfront pockets — a tight strip of $1.5M-$3M owner-occupier homes wrapped around a surf break, with Copacabana to the north and North Avoca on the headland behind the lagoon. Most of our work here is full-residential installs in the $25,000-$50,000 bracket, commissioned during a renovation or a knock-down-rebuild. The Erina workshop is roughly 10 minutes away via Avoca Drive, which means we run Avoca jobs as same-day callouts and keep the spares cabinet stocked with the exact hardware these homes already use.
Three things separate an Avoca install from anywhere else we work. Salt air sits on every exposed sensor and switchplate. The houses are built for entertaining, so the audio-visual and outdoor lighting have to behave like one system. And the driveways are short and visible from the street — security has to deter rather than just record. We treat those three constraints as the design brief, and every component selection on an Avoca job traces back to them.
Salt-Air-Graded Hardware (Not Standard Smart Home Kit)
Direct ocean-facing positions at Avoca, Copacabana and North Avoca corrode standard smart-home hardware inside 12 months. Plastic-bodied PIR sensors yellow and crack, exposed contacts on cheap relays oxidise, and Wi-Fi outdoor cameras with painted aluminium housings show pitting by the second summer. We specify IP67-rated Reolink Duo 3 cameras for the high-mount coverage positions, Aqara T1 outdoor motion sensors with the metal mounting plates replaced with marine-grade 316 stainless, and Shelly Plus 1PM relays installed inside IP66 sealed enclosures rather than in the original light fittings. Every exterior cable run is in UV-stable conduit rather than zip-tied to eaves. The cost premium over a standard install runs about 12-15%, and the failure rate on a five-year horizon drops from "expect to replace half of it" to "expect one or two replacements."
Integrated AV for Beachfront Entertaining
Avoca houses get used. Friday evenings, summer holidays, NYE — these homes are entertaining venues for 15-30 people regularly, and the AV has to behave that way. We integrate the existing equipment (typically a Sonos Amp or two, a 65-75" wall-mounted display, and an outdoor speaker zone wired to a covered deck) into Home Assistant so a single "Entertaining" scene drops the inside lights to 30%, brings the deck lights up, switches the kitchen Sonos zone to the deck zone, sets the climate-control system to a higher temperature on the assumption the doors will be open, and disables the indoor motion-triggered automations so nothing turns itself off mid-conversation. The dashboard lives on a wall-mounted iPad in the kitchen, the same iPad the family uses for recipes and the school calendar — there's no separate "smart home interface" to learn.
Pool and Outdoor Lighting on One Schedule
Most full-resi Avoca jobs include a pool, an outdoor lighting circuit running 12-20 fixtures across the garden and pathways, and a heat pump for the pool. Run separately, these three systems waste meaningful energy — the pool pump cycles whenever it feels like, the lighting runs from dusk to a fixed time, and the heat pump fights against the pump schedule. We tie them together through our pool and spa integration service so the pump runs during solar peak hours, the heat pump targets a swimmable temperature only when the weather forecast supports it (no point heating the pool for a 22-degree rainy weekend), and the path lighting comes up at civil dusk based on actual sky brightness rather than a fixed clock. A typical four-bedroom Avoca install with pool and full outdoor lighting comes in around $32,000-$42,000 commissioned, of which the pool and garden circuits are roughly a third.
Driveway and Front-of-House Security
Avoca driveways are short and visible — there's no long approach to monitor, just a 10-15 metre run from the road to the garage. The security question here is "did the right person just arrive" and "is anyone loitering at the front gate", not "review yesterday's six-hour video log". We mount a single Reolink Duo 3 at first-floor eave level covering the driveway, garage door, and front path in a single frame, run the AI person-and-vehicle detection on a local Frigate instance (no cloud subscription, no monthly fee), and push notifications to the homeowner's phone only when the model is confident a person is on the property. The garage door integrates via a Shelly 1 across the existing motor's manual-button contacts, and a Reolink TrackMix on the side of the house covers the gate and pool fence. Pair this with our local detection-based camera setup and you get useful notifications instead of an inbox full of "leaf blew past camera" alerts.
Why Avoca Owners Renovate Instead of Selling — and What That Means for the Install
The $1.5M-$3M Avoca stock turns over slowly. Most of the homes we work on are owned by families who bought 10-25 years ago, renovated once in the 2010s, and are now doing a second-round refresh — adding a second storey, redoing the kitchen, replacing the pool. That means we're almost always working alongside a builder rather than on a finished house. Done right, this is the cheapest time to install a full system: cable runs go in before the plasterer, the network closet gets a proper location in the garage rather than a hallway cupboard, and the climate-control wiring lands on the right walls. We work with the builder's electrician on a structured-wiring plan in the first two weeks of site, then come back for commissioning once the trades have cleared out. Talk to us early via our free pre-renovation assessment — the difference between a 14-day install and a 4-day install is usually whether anyone called us before the gyprock went up.
Frequently Asked Questions
How far is Avoca Beach from your Erina workshop?
About 10 minutes via Avoca Drive in normal traffic. We treat Avoca, Copacabana and North Avoca as same-day-callout territory — if a sensor fails on a Tuesday morning, we can usually be there before lunch with a replacement.
Do you do partial installs, or only full-residential packages?
Both. A typical full-resi job at Avoca runs $25,000-$50,000 commissioned. But we also do single-room or single-system jobs — pool integration on its own, or a security retrofit, or a custom dashboard — starting around $2,500. The page above describes the full-resi pattern because that's the most common Avoca enquiry, not because it's the only thing we install.
Will the salt-air-graded hardware actually look different from a normal install?
Mostly no. The internal switchplates and sensors look the same as any other Aqara or Lutron install. The visible differences are at the exterior camera positions (the housings are slightly bulkier IP67 units) and the network closet (sealed cabinet rather than open shelving). Inside the wall cavities the conduit and stainless fixings aren't visible at all.
Can you integrate an existing pool heat pump or do we need to replace it?
We integrate first, replace only if the existing unit doesn't support a control interface. Most heat pumps installed in the last 8 years have either a Modbus interface or a simple 24V remote-control input that we can drive from a Shelly relay. The handful of older units that don't get a Sonoff-based override on the main contactor — not elegant, but functional, and a fraction of the cost of a new heat pump.
