Officially Works with Home Assistant certified via Matter over Thread, the Pro (5th gen) uses the same retrofit-over-your-cylinder fitting as the £139 Go, but at £229 it swaps 4 AA batteries for a built-in rechargeable Li-ion pack that charges via USB-C in about 2 hours and lasts roughly 6 months per charge. The extra ~£90 also buys a Wi-Fi radio for Nuki's remote-access feature and, more usefully for HA users, a port for the optional Door Sensor accessory the Go lacks entirely. Worth it for fewer battery swaps and door-open/closed state; skip it if the Go's bare lock entity covers your needs.
What can Home Assistant control on the Nuki Smart Lock Pro (5th generation)?
| Control | Type | What it does |
|---|---|---|
| Lock | Lock | Lock/unlock via the Matter door lock cluster, fully local over Thread — identical control surface to the Go. |
| Battery | Sensor (%) | Battery reading from the Matter power-source cluster. |
| Door sensor | Binary sensor | Open/closed state from the paired Nuki Door Sensor accessory — a real Matter-exposed entity on the Pro, unlike the Go which has no hardware slot for the accessory at all. |
| Operating mode | Select | Switches the lock's Matter operating mode; not exposed at all through the Bridge or MQTT paths, only Matter. |
| Thread signal | Sensor | Diagnostic sensor for the Thread network link, useful for debugging commissioning/reliability issues with border routers; absent from Bridge and MQTT integrations. |
Matter commissioning for the Pro runs over Bluetooth-to-Thread exactly like the Go — the built-in Wi-Fi radio only backs Nuki's own cloud remote-access feature, so it doesn't shortcut pairing or improve reliability against Thread border router issues, a real-world gotcha reported by Pro owners around NAT64 configuration. Where the Pro genuinely pulls ahead of the Go is the optional Nuki Door Sensor accessory: the Go has no port for it at all, while the Pro's paired sensor reports open/closed as its own binary sensor entity through HA's Matter integration. Don't expect the older native nuki integration plus Bridge to unlock materially richer entities either — PIN codes and the activity log stay locked in the Nuki app regardless of path; only a third-party HACS integration querying Nuki's cloud API surfaces that data, since neither the Bridge's local API, MQTT, nor Matter exposes it locally.
Specs
| dimensions | Approx. Ø57 x 70mm, around 290g |
|---|---|
| battery life | Roughly 6 months per charge under typical use, full recharge takes about 2 hours over USB-C |
| battery type | Built-in rechargeable lithium-ion battery pack, charged via USB-C — no AA batteries, unlike the Go |
| connectivity | Built-in Wi-Fi, Bluetooth and Thread (Matter certified) — the Wi-Fi radio backs Nuki's own cloud remote-access feature rather than improving Matter/Thread pairing or reliability |
| backup access | Existing physical key still works from outside via the unchanged cylinder, identical to the Go |
| keypad or fingerprint | Nuki Keypad 2.0 sold separately for PIN entry; no fingerprint reader offered |
| cylinder compatibility | Retrofits over an existing key & knob euro-profile cylinder, same fitting principle as the Go — no cylinder swap or drilling required (the pricier Smart Lock Ultra needs the cylinder itself replaced) |

Frequently asked questions
- Does the Nuki Smart Lock Pro (5th generation) work with Home Assistant locally?
- Yes. The Nuki Smart Lock Pro (5th generation) 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 Pro (5th generation) use, and do I need a hub?
- The Nuki Smart Lock Pro (5th generation) uses Wi-Fi and Thread and Matter and Bluetooth. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly; 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 a Bluetooth adapter on your Home Assistant host or an ESPHome Bluetooth proxy. Nuki's own hub is not required when you integrate through a certified "Works with Home Assistant" integration (matter).
