Ultraloq U-Bolt
Score: 85/100Rankings
The ULTRALOQ U-Bolt is a versatile smart deadbolt offering keyless entry via fingerprint, PIN, app, NFC, and voice assistants, featuring Matter-over-Thread compatibility for seamless integration with major smart home ecosystems. It provides auto-unlock geofencing and durable IP65 weatherproofing, making it suitable for DIY installation on standard US doors. However, remote access features often require purchasing an additional WiFi or Z-Wave bridge.
The Ultraloq U-Bolt Pro is a versatile, Grade 1 certified smart deadbolt featuring built-in WiFi and an impressive 8-in-1 entry method suite. Its main trade-offs are the high battery consumption from WiFi connectivity and the limitation to 2.4GHz networks. It is ideal for tech-savvy homeowners and Airbnb hosts who need robust remote access and door-ajar alerts.
