Smart Lock U400
The Smart Lock U400 is a UWB-enabled smart lock that brings hands-free unlocking to a new level of safety and convenience. Simply approach the door and it unlocks automatically. Built on Matter over Thread and the Aliro standard, it works seamlessly across devices and ecosystems for long-term, future-proof stability.

Additional unlocking options are always available, including advanced fingerprint recognition (with a 0.00001% false acceptance rate), anti-peep passwords, one-time and scheduled temporary passwords, remote unlocking via a Thread-enabled Matter controller, and a physical key backup. Powered by a rechargeable battery, U400 is designed for reliable, everyday use without compromise.

The U400 has been a major upgrade for my smart home setup. It brings a real VIP feel to not need to have my phone or Apple Watch unlocked or out of my pocket when approaching the door. It unlocks without fail every time I approach and reach for the door handle. The door sensing that’s built in also means that the door locks itself 3 seconds after the lock senses that the door is fully closed.

It has a rechargeable battery pack that can be recharged while still in the lock, or with a standalone usb c charger for a faster charge when it’s not plugged into the lock. Firmware improvements also led to phenomenal battery life expectancy with months between charges. :sunglasses:

Pairing was initially a nightmare with HomeKit, but has gotten better with updates. Home Assistant had no issues at all with adding the u400, it was nearly instant. Thankfully, I haven’t had any issues with this lock not maintaining connection, which is refreshing since my Schlage sense lock has been losing connection hourly lately, so it was an easy choice to retire that lock and replace it with the u400.

Can this lock be installed on an outdoor backyard gate? I’m trying to see whether the IP65 weatherproof rating applies to both sides of the lock, the inside and the outside. On a backyard door setting, both sides are exposed to the elements.
