Nuki Smart Lock Pro 5th generation

Quick verdict

Nuki's 5th gen Pro is a go-to smart lock for Home Assistant. Matter over Thread (plus built-in Wi-Fi) means it talks directly to your network with no bridge or cloud in the middle. It clamps onto your existing cylinder, so installation is non-destructive. Nuki sells both Euro-cylinder and US single-cylinder deadbolt versions, so US buyers should just confirm they pick the US deadbolt model. The price is steep, but you get a fully local smart lock.

Standout: Matter over Thread retrofit smart lock (Euro-cylinder and US single-cylinder deadbolt versions) with built-in Wi-Fi, no hub and no cloud required.

Why it stands out

  • Matter over Thread (plus built-in Wi-Fi) means no hub, no bridge, no cloud for a fully local smart lock
  • retrofits over existing hardware without replacing the cylinder; Nuki sells both Euro-cylinder and US single-cylinder deadbolt versions
  • Thread mesh networking gives excellent range and reliability

Reasons to hesitate

  • the original Pro is Euro-cylinder oriented; US buyers should confirm they are getting the US single-cylinder deadbolt version
  • premium price point for a retrofit lock adapter
  • Thread border router required on your network for Matter connectivity

Best for

  • Home Assistant users wanting a local-first smart lock with no cloud dependency
  • anyone with a Euro-cylinder or US single-cylinder deadbolt who wants Matter over Thread

Avoid if

  • you have a non-cylinder or mortise lock not covered by Nuki's adapter range
  • you want a built-in keypad or fingerprint reader. Those are separate Nuki accessories

Privacy and local-control notes

Matter over Thread is fully local. No cloud account required for basic operation. Nuki cloud is optional for remote access and guest management.

Home Assistant support: supported · integration path: Matter.

Buying reality check

Price notes: Premium pricing but you avoid recurring cloud fees. Keypad and fob accessories are sold separately.
