Ultraloq U-Bolt Pro Z-Wave

Quick verdict

The Ultraloq U-Bolt Pro Z-Wave packs five unlock methods into a surprisingly compact design. Z-Wave gives you fully local Home Assistant control via Z-Wave JS, while the fingerprint reader handles day-to-day entry. You'll need a Z-Wave controller, but once set up, it's one of the most versatile smart locks available for local-first setups.

Standout: Five unlock methods in one lock — fingerprint, keypad, Bluetooth, Z-Wave, and physical key.

Reasons to hesitate

Best for

Privacy and local-control notes

Z-Wave control is fully local through Home Assistant. Bluetooth is device-to-device. The U-tec app uses cloud for remote access, but Z-Wave operation needs no cloud. Fingerprint data stored locally on the lock.

Home Assistant support: supported · integration path: zwave_js.

Buying reality check
