Nuki Smart Lock Pro (5th Gen)

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.
