The catch
It's sold as an outdoor-capable deadbolt, but the IP45 weather rating and lack of a physical security certification make it appropriate only for interior doors.

Spec, translated

The 'Remote Control via Tuya App' feature works only via Bluetooth when your phone is within about 30 feet of the door; controlling it from anywhere else requires a separate Wi-Fi hub.

Lab notes
The observations that actually change the buying decision.
01
The IP45 rating signifies protection from light water spray, not driving rain; this lock is unsuitable for any door not under a deep, protective overhang.
02
True remote control (e.g., from work) requires purchasing a separate Tuya Bluetooth-to-Wi-Fi gateway, a crucial detail omitted from the primary marketing.
03
The lock lacks any specified ANSI/BHMA security grade, meaning its physical resistance to forced entry is uncertified and should be considered minimal.
04
The claim of '8000+ unlock cycles' is a theoretical maximum under ideal conditions; real-world battery life will be significantly shorter due to temperature, use patterns, and standby drain.

Why you should buy

This product makes sense for an interior door, like a home office or storeroom, where basic access control and convenience are prioritized over physical security. It's also a budget option for landlords managing access to individual rooms within a rental property.

Why you should skip

Anyone seeking to secure a primary exterior door should invest in a lock with a stated ANSI/BHMA grade and a higher IP rating (IP56+). Buyers who need reliable remote access out of the box will be disappointed by the need for a separate, unincluded gateway.

What buyers actually say
