Nuki Smart Lock Pro 5th generation

Quick verdict

Nuki's 5th gen Pro is the go-to smart lock for European homes running Home Assistant. Matter over Thread means it talks directly to your network with no bridge or cloud in the middle. It clamps onto your existing Euro-cylinder, so installation is non-destructive. The price is steep, but you get a fully local smart lock. US buyers should look elsewhere. This is built for European door hardware.

Standout: Matter over Thread smart lock for European cylinder locks with no hub and no cloud required.

Why it stands out

  • Matter over Thread means no hub, no bridge, no cloud for a fully local smart lock
  • fits European cylinder locks without replacing the existing hardware

Reasons to hesitate

  • designed for European cylinder locks, not compatible with US deadbolts
  • premium price point for a retrofit lock adapter
  • Thread border router required on your network for Matter connectivity

Best for

  • European Home Assistant users wanting a local-first smart lock with no cloud dependency
  • anyone with a Euro-cylinder door who wants Matter over Thread

Avoid if

  • you are in the US or have a deadbolt-style lock. This is designed for European cylinders
  • you want a built-in keypad or fingerprint reader. Those are separate Nuki accessories

Buying reality check
