Not a front-door lock — it wires into an existing door-entry buzzer/intercom system (flats, apartment blocks) to trigger the electric strike remotely; wrong pick if your problem is actually a euro-cylinder front door. Runs on 4x AAA batteries (about a year) or permanent micro-USB power. The Opener itself only speaks Bluetooth — no built-in Wi-Fi — so the separate Nuki Bridge is mandatory for remote access and for the Home Assistant integration's Bridge HTTP API. Self-install is realistic via the Nuki app, but you're wiring into a shared intercom panel, so it suits confident DIYers more than total beginners.
What can Home Assistant control on the Nuki Opener (Smart Door Opener)?
| Control | Type | What it does |
|---|---|---|
| Lock | Lock | Reports unlocked when Ring-to-Open or continuous mode is active and locked otherwise; lock/unlock toggle that arm state rather than releasing the strike. |
| Open | Service | One-shot action that immediately releases the electric strike via the Bridge, independent of Ring-to-Open/continuous mode state. |
| Continuous mode | Service | Enables or disables the Opener's continuous unlock mode, which holds the strike permanently releasable; separate from the lock entity's own state. |
| Ring | Event | Fired when the Opener detects the intercom's own ring signal, picked up on the Bridge's poll cycle — usable as an automation trigger for ring-then-decide flows. |
The Opener is modelled in HA as a lock entity with inverted semantics: calling unlock doesn't buzz the door, it arms Ring-to-Open so the next physical ring on the intercom auto-triggers the strike, and calling lock disarms it — the one-shot buzz-it-open-now action is a separate open service, while continuous mode has its own dedicated service call rather than reusing lock state. The integration also fires an event when the Opener detects the intercom's own ring signal — a genuine automation trigger — but it's surfaced via the Bridge's poll cycle, not an instant webhook, so treat it as near-real-time rather than instant. That makes a workable pattern: trigger on the ring event, push an actionable mobile notification, and only call the open service if the resident confirms — a remote answer/buzz-in flow that never leaves Ring-to-Open permanently armed.
