Nuki's entry-level 5th-gen lock is officially Works with Home Assistant certified via Matter over Thread and clamps onto your existing key & knob cylinder with no drilling — ideal first smart lock for UK uPVC/composite doors, though multipoint doors need the handle lifted before it can throw the deadbolt. At £139 it sits between the Aqara U200 Lite (£128, not HA-certified) and Yale Linus L2 (£189, Matter over Wi-Fi). Unlike the pricier Nuki Pro (£229) and Ultra, the Go runs on 4 replaceable AA batteries with a single-speed brushed motor, and dedicated remote access costs extra rather than being included.
What can Home Assistant control on the Nuki Smart Lock Go?
| Control | Type | What it does |
|---|---|---|
| Lock | Lock | Primary lock entity — supports lock/unlock/open and reports locked, unlocked, locking, unlocking; jammed states aren't surfaced due to the current HA Matter mapping gap. |
| Battery | Sensor (%) | Battery percentage from the Matter power-source cluster; over-frequent HA polling of lock status has been reported to measurably shorten battery life. |
| PIN codes / access schedules | Unsupported | Not exposed via Matter — PIN credential management stays Nuki-app-only, so no HA entity or service exists for this. |
| Auto-lock / auto-unlock config | Unsupported | Configured only in the Nuki app; automations must replicate the behaviour externally (e.g. HA-side geofencing or timer-based lock calls) rather than toggle a native config entity. |
| Door position sensor | Unsupported | Not available on the Go hardware; no binary sensor for door-open/closed state is created by the integration. |
Matter over Thread on the Go exposes only a bare lock entity (locked/unlocked/locking/unlocking) plus a battery sensor — PIN code management and auto-lock/auto-unlock scheduling stay app-only and never surface as HA config entities. Commissioning goes through the Nuki app's share-to-fabric flow into an existing Thread border router rather than a direct HA QR scan, and community threads report lock/unlock state-change events firing unreliably as automation triggers, so treat them as best-effort rather than guaranteed. A known HA/Matter gap compounds UK multipoint use: the door lock cluster can report a jammed state when the deadbolt can't throw because the handle wasn't lifted first, but HA's Matter integration currently maps that straight to unlocked instead of a distinguishable jammed state — so a lock-failed automation has to watch for the state staying unlocked a few seconds after a lock call, rather than for a jammed state that never appears.
Specs
| dimensions | 110 x 60 x 60mm; official weight not published by Nuki |
|---|---|
| battery life | Not officially published by Nuki for AA operation on the Go — expect noticeably shorter runtime than the ~6 months quoted for rechargeable rivals like the Aqara U200 Lite or Yale Linus L2, since the Go also uses a single-speed brushed motor rather than the Pro/Ultra's more efficient brushless motor |
| battery type | 4x AA batteries (replaceable, included in box); Nuki's rechargeable Power Pack is a separate optional add-on |
| connectivity | Built-in Wi-Fi and Thread (Matter certified); Bluetooth for app pairing/setup; dedicated remote/cloud access sold separately as an add-on |
| backup access | Existing physical key still works from outside via the unchanged cylinder, since the Go clamps onto the knob side rather than replacing the cylinder itself |
| keypad or fingerprint | None built in — Nuki Keypad sold separately for PIN entry; no fingerprint reader offered at this tier |
| cylinder compatibility | Retrofits over an existing key & knob euro-profile cylinder — no cylinder swap or drilling required; motor housing mounts over the indoor thumbturn |

Frequently asked questions
- Does the Nuki Smart Lock Go work with Home Assistant locally?
- Yes. The Nuki Smart Lock Go is controlled locally in Home Assistant through a certified "Works with Home Assistant" integration (matter), so it keeps working if your internet connection or the Nuki cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Nuki Smart Lock Go use, and do I need a hub?
- The Nuki Smart Lock Go uses Bluetooth and Thread and Matter and Wi-Fi. To pair it with Home Assistant you need a Bluetooth adapter on your Home Assistant host or an ESPHome Bluetooth proxy; or a Thread border router (Home Assistant Connect ZBT-1, Apple TV 4K or a HomePod mini all work); or a Thread border router if it is Matter-over-Thread, or just your Wi-Fi network if it is Matter-over-Wi-Fi; or no hub — it joins your Wi-Fi network directly. Nuki's own hub is not required when you integrate through a certified "Works with Home Assistant" integration (matter).
- How much does the Nuki Smart Lock Go cost in the UK?
