How TTLock, Igloohome, Yale Home, Carbine Connect and Forge Smart (Tuya) compare across architecture, security, data sovereignty and use-case fit — so you can choose the right platform before you buy the hardware.
When you buy a smart lock, you are buying two things at once: the physical hardware on your door, and the software platform that manages everything behind it. The platform determines how credentials are created and shared, whether remote access is possible, how audit trails are stored, where your data lives, and what happens when the internet goes down. Two locks that look identical on a shelf can behave completely differently because they run on different platforms.
Gold Coast Smart Locks stocks hardware across five platforms: TTLock (the Sciener cloud platform, running McGrath, Lockton, Austyle, Vault and the TTLock half of the FORGE range), Igloohome (algoPIN offline technology), Yale Home / Lockwood Home (ASSA ABLOY — one platform under two brand apps; the only one in our range with native Apple HomeKit), Carbine Connect (Bluetooth-only, no cloud), and — since October 2026 — Forge Smart (Tuya), FORGE’s own app on the Tuya platform, with Wi-Fi built into the lock. Tuya is also the platform behind most generic smart locks sold through marketplaces; the FORGE range is the only Tuya-platform hardware we stock and support. This chapter covers each platform's architecture, feature set, security profile, and data sovereignty so you can make an informed decision before committing to hardware.

TTLock passcode types at a glance:
| Type | Key behaviour | Use case |
|---|---|---|
| Permanent | Must be used within 24 hrs of generation. Then valid indefinitely until revoked. | Family, permanent staff |
| Time-Limited | Valid from/to a specified window (hour-accurate up to 1 year; month-accurate beyond 1 year). Must be activated within 24 hrs of start date. | Guests, contractors, fixed-period access |
| One-Time | Single use only. Valid for 6 hours from generation. | Delivery, tradespeople, one-off entry |
| Erase | Valid 24 hrs. When used, deletes ALL passcodes from the lock. Dangerous if shared. | Emergency full reset only |
| Cyclic | Repeats daily, weekday, weekend, or specific day. Must be activated within 24 hrs of first validity window. | Cleaners, regular visitors, office staff |
| Customised | User-defined code (4–9 digits), custom validity window. Remotely configurable via gateway. | Preferred PIN for permanent users |
In March 2024, CERT/CC published advisory VU#949046 documenting eight unpatched vulnerabilities in the Sciener firmware, TTLock app and G2 gateway that underpin TTLock, McGrath, Lockton, Austyle, Vault and FORGE’s TTLock locks. Sciener was notified in November 2023 and did not respond; as at 1 November 2026 its vendor status on the note is still “Unknown” and the note was last revised on 18 March 2024. Gold Coast Smart Locks discloses these in full below; the canonical treatment, with mitigations, is Chapter 14’s security section.
| CVE | Vulnerability |
|---|---|
| CVE-2023-7006 | unlockKey brute-forceable — no rate limiting on Bluetooth challenge requests. An attacker can cycle through challenge/response pairs to derive the unlockKey. |
| CVE-2023-7005 | Encryption protocol downgradeable — the lock can be induced to switch from encrypted to plaintext communication, exposing credentials in transit. |
| CVE-2023-7003 | AES key reuse — all locks with wireless keypads share the same AES key. A key recovered from one device applies to all. |
| CVE-2023-6960 | Deleted virtual keys persist — eKeys that have been revoked remain functional on the lock's internal store and can be reused by an attacker who captured them before deletion. |
| CVE-2023-7004 | Lock spoofing — the app does not properly verify it is talking to the expected lock, so a device spoofing the lock’s MAC address can harvest the unlock key. Bluetooth proximity required. |
| CVE-2023-7007 | Gateway impersonation at the server — the one server-side flaw: Sciener’s servers did not validate G2 gateway connection requests, so an attacker who knew a gateway’s MAC address could impersonate it and receive its messages, including the unlock key (G2 firmware 6.0.0 listed; G5 not stated). |
| CVE-2023-7009 | Plaintext commands accepted over Bluetooth — some locks process short unencrypted messages as if encrypted, letting a nearby attacker pass malicious commands. |
| CVE-2023-7017 | Unauthenticated firmware update over Bluetooth — some locks accept a firmware image without authenticating it, so an attacker within range could load arbitrary firmware. |

The table below maps common Australian installation scenarios to the platform that best fits. For complex situations — fire doors, DDA requirements, strata rules, coastal environments — the right platform depends on hardware compatibility as much as software preference. If no app is wanted at all, the prior question is answered in Chapter 16 — mechanical versus smart.
| Your situation | Recommended platform | Key reason |
|---|---|---|
| Airbnb host — 1 to 3 properties, want automated guest access | Igloohome | algoPIN + Airbnb Connect automate guest codes without WiFi at the property or a PMS subscription |
| Short-stay host using a PMS (Hospitable, Uplisting, RemoteLock etc.) | TTLock / McGrath | Native API integration with all major PMS platforms; booking-triggered code creation across channels |
| 5+ properties, multi-platform bookings, need attendance tracking | TTLock / McGrath | Scale; attendance management built in; one account manages hundreds of locks |
| Apple HomeKit home automation | Yale Home | Only platform in the Gold Coast Smart Locks range with native HomeKit; Alexa and Google Home also supported via Hub 2 |
| Want DoorSense — real-time door open/closed/ajar monitoring | Yale Home | DoorSense is built into the Yale Connect Plus Hub 2; no other platform in the Gold Coast Smart Locks range offers equivalent |
| Home or small office — privacy priority, prefer no cloud | Carbine Connect | Bluetooth-only; no event data in cloud; SilentGrid-audited; proximity management is sufficient |
| Property with unreliable NBN or no internet at the site | Igloohome | algoPIN guest codes work without internet at the property; also works at construction sites and caravans |
| Fire-rated door — requires AS1905.1 certification | McGrath (Hamilton series) or Yale (Unity DDA) | Fire-tested hardware; platform is secondary to hardware compliance. See Chapter 05 — Fire Doors |
| DDA / NDIS accessible lever — AS1428.1 compliant | McGrath (Albion/Hamilton) or Yale (Unity DDA) | Lever geometry is the compliance driver; platform is secondary. See Chapter 09 — DDA & NDIS |
| Strata building — need gateway without WiFi at the common-area comms room | TTLock / McGrath G3 | G3 gateway uses Ethernet/PoE — no WiFi required. Suitable for IT-managed environments |
| Remote holiday home with unreliable NBN but 4G coverage | TTLock / McGrath G4 | G4 gateway has 4G SIM fallback; remote access maintained when NBN drops |
| Gate or outdoor entry where Wi-Fi reaches the door, and you would rather not buy a gateway | Forge Smart (Tuya) — FORGE H100 | IP68 double-sided gate lock with Wi-Fi built in; remote passcodes and entry records with no gateway. If you need on-demand off-site unlock, take the TTLock H10D and a G5 instead |
| Want remote passcodes and entry records without a gateway, and approving a visitor’s request from your phone is enough | Forge Smart (Tuya) | Wi-Fi direct to cloud; request-based remote unlock. Not for scheduled passage mode, voice assistants or PMS automation — those are TTLock-with-gateway features |
The table below summarises the security and data residency profile of each platform. "Cloud needed for entry" means whether the internet must be live at the property for a guest or user to unlock the door — the answer is no for all five Gold Coast Smart Locks platforms, which is the minimum standard we consider acceptable for residential and short-stay use.
| Platform | CVEs published | Vulnerability scope | Data residency | Cloud needed for entry? | Independent security audit? |
