Terrigal is our backyard. The Erina workshop is a five-minute drive from The Haven, so we treat Terrigal, Wamberal and Avoca Beach as local jobs — same-week site visits, no travel surcharge, and we usually batch three or four beach-suburb jobs into a single delivery run. The two customer profiles that dominate Terrigal enquiries are the resident owner-occupier with a $1.5M-$3M house wanting full coverage, and the Airbnb host running a 3-4 bedroom beach rental who needs to control the property remotely without an on-site manager.
The Terrigal Airbnb Automation Pack ($6k-$12k)
For a typical 4-bedroom Terrigal rental — the most common Airbnb stock between Pine Tree Lane and Avoca Drive — we install a defined automation pack in the $6,000-$12,000 bracket. The variance is mostly down to how much existing wiring we work with and how many cameras are needed for the property layout.
The headline pack: a Yale or Aqara smart deadbolt on the front door (managed via Home Assistant with rotating per-booking codes synced from your Airbnb calendar), a Reolink Duo dual-lens camera on the driveway with AI person and vehicle detection (no faces in the recording — guest privacy matters), three Aqara FP2 mmWave presence sensors covering the entry hall, main living and master bedroom for occupancy-aware climate, a Shelly EM3 on the main switchboard so you can see AC and pool-pump draw remotely after checkout, and a custom Lovelace host dashboard you check from anywhere with the booking calendar overlaid against actual occupancy.
The single most-requested feature: a "checkout audit" automation that runs at 11am on changeover day — it checks every door is locked, the AC is set to away mode, no taps are flowing (via the leak sensor under the laundry tub), and the pool pump is on its day cycle. If anything's wrong, you get a single phone alert before the cleaner arrives.
Hardware Spec That Survives a Terrigal Easterly
Most off-the-shelf consumer smart-home gear fails within a year on this coast. Standard zinc-plated camera mounts pit and bleed rust within a wet season. Indoor-only Zigbee sensors stuck on a verandah die in the first salt-spray storm. We pick hardware by spec, not by Amazon star rating.
For outdoor cameras, the Reolink Duo (PoE, IP67-rated housing, local NVR recording — never cloud) handles a Wamberal easterly fine, but every cable penetration gets sealed with Sikaflex and the brackets are 316 stainless. For outdoor presence sensors we run IP67-rated Zigbee2MQTT contacts on Zigbee channel 15 (avoids most local Wi-Fi interference) and we keep the coordinator radio on a Sonoff ZBDongle-E inside the house with at least two router devices in line-of-sight to extend mesh to the boundary.
Indoor: Aqara FP2 mmWave sensors at roughly $150 each are the workhorse for occupancy-aware climate and lighting — they distinguish a person from a curtain blowing in the breeze, which old PIR sensors couldn't. Smart switches behind existing wall plates use Shelly 1PM Mini (Wi-Fi, dimmable, fits a standard Aussie GPO box) so we don't rewire. All of this gets commissioned through our automation and Home Assistant commissioning service.
Pool, Spa & Hot Tub Integration
Most Terrigal premium homes have a pool or spa, and that's where the energy bill quietly bleeds. We schedule pool pumps to run on solar production windows via our energy monitoring and solar-tariff optimisation service — usually a 35-50% reduction in pool running cost compared to a fixed nightly cycle. Water temperature sensors, salt-cell health, and chlorine pump status all feed Home Assistant. For Airbnb pools, a Zigbee contact sensor on the pool gate sends an alert if the gate opens after 10pm or before 7am — useful for both safety and insurance documentation.
Spa-equipped Wamberal and Avoca properties get the same plus a remote pre-heat trigger so guests arriving Friday evening have the spa at temperature without an electrician's "always-on" 38°C standby setting bleeding power all week.
Wamberal Lagoon & Beach Erosion Awareness
The one thing Terrigal customers ask about that no other Central Coast page can honestly cover: the Wamberal lagoon and beach erosion exposure. Homes on Ocean View Drive and the Wamberal beachfront sit a few hundred metres from a coastline that has lost significant frontage in past easterly swell events. Properties backing onto Wamberal Lagoon also face occasional flood exposure when the lagoon overtops.
We can't change the geography. What we can do: install BOM weather feeds into Home Assistant that issue alerts on extreme swell forecasts (so an absent owner has a day or two of warning), pre-deploy automation that closes hard shutters on east-facing windows when wind gusts exceed a configured threshold, and run a $35 leak sensor at the lowest internal point of the garage or laundry that fires three days before water reaches the timber. These aren't crisis features, they're early-warning. We discuss them honestly with every Wamberal customer.

Frequently Asked Questions
How far is Terrigal from your workshop?
Five minutes — our workshop is in Erina, just west of Terrigal across the Central Coast Highway. We treat Terrigal, Wamberal and Avoca as local jobs with same-week site visits and no travel loading on the quote.
Can you manage an Airbnb code automation that syncs with my booking calendar?
Yes. Home Assistant pulls your Airbnb iCal feed and rotates per-booking smart-lock codes automatically. Each guest gets a unique code that activates at check-in time and expires at checkout. We've run this on Yale Assure Lock SL and Aqara U100 deadbolts with reliable results.
How does your hardware hold up to the salt air?
Outdoor camera mounts are 316 stainless steel, all cable penetrations are sealed with Sikaflex, and we only use IP67-rated Zigbee or PoE-Ethernet devices outdoors. Most installs are still on original hardware three to five years in. The exception is some early-generation outdoor Wi-Fi gear we no longer recommend — the brackets and weather seals on those failed within 18 months.
What's your response time for a Terrigal fault call?
Same-day for remote diagnosis (most issues we fix without leaving the workshop). Physical site visits within 24-48 hours for non-emergencies, same-day for active rental properties with guests on site.
