Door-sense evidence was limited but positive, centered on the built-in gyroscope knowing when the door closes so it can lock without an added sensor.
Pros: Battery, Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
Door-sense is a clear strength, with reviewers praising the hidden sensor and the ability to know whether the door is actually closed.
Pros: Palm vein recognition, Battery
Cons: Feature additions via updates, Geofencing
Door-sense feedback was positive where tested; reviewers liked the added sensor and remote reporting of open/closed and lock/unlock state.
Pros: Fingerprint, Installation and Setup
Cons: Hub requirement
Door-sense was useful and often praised, though one reviewer estimated it at about 80% accuracy and used an extra contact sensor for certainty.
Pros: Fingerprint, Value and Price
Cons: Hub requirement, Battery
Door-sense worked in the reviewer’s test, with the app state updating once the door closed.
Pros: Installation and Setup, Facial recognition
Cons: Value and Price, Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
DoorSense and door-open detection were mostly viewed as reassuring and helpful, though setup and flush-mount installation caused friction for some reviewers.
Pros: Installation and Setup, Value and Price
Cons: Keypad, Auto-lock
The door sensor was useful for door-open awareness and auto-lock behavior, but reviewers disliked its looks and noted it was not exposed to Apple Home.
Pros: Fingerprint, Installation and Setup
Door-sense received qualified praise because it can infer door state without a separate sensor, though with some edge-case caveats.
Pros: Palm vein recognition, Camera and doorbell performance
Cons: Door compatibility (deadbolt fit)
DoorSense was useful for knowing door status and enabling safer auto-lock behavior, but installation, appearance, and occasional calibration behavior were recurring caveats.
Pros: Installation and Setup, Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
Cons: Wi-Fi, Battery
DoorSense was praised when it worked and was considered worth installing, but one reviewer reported repeated calibration failures and incorrect open/closed status.
Pros: Installation and Setup, App
Cons: Battery
Door-sense split reviewers: one was impressed by the built-in sensor, while another liked the idea but found it not reliable enough for exact door position.
Pros: Value and Price, Guest Codes and Access
Cons: Industrial design, Hub requirement
Door-sense evidence was mixed: departure detection was useful, but one reviewer criticized the lock for not knowing whether the door was open.
Pros: Installation and Setup, Camera and doorbell performance
Cons: Door compatibility (deadbolt fit)
Door-sense was split: one reviewer found the sensor useful for auto-lock, while another said the magnet still reported the door state unreliably.
Pros: Installation and Setup, Industrial design
Cons: Hub requirement, Auto-lock
Door-sense was the most consistent hardware complaint: it worked accurately for some reviewers, but many disliked the exposed wired sensor or complicated sensor alternatives.
Pros: Facial recognition, Installation and Setup
Cons: Door-sense, Wi-Fi
Door-sense was a clear weakness because reviewers noted there is no door sensor and the bolt can extend while the door is open.
Pros: Value and Price, Fingerprint
Cons: Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread), Door-sense
Door-sense was a repeated weakness because the lock does not know whether the door is actually shut, making auto-lock behavior less safe.
Pros: Fingerprint, User access management
Cons: Notifications, Auto-lock
Reviewers wanted true door-sense behavior; the repeated concern was that the lock cannot tell whether the door is actually closed.
Pros: Installation and Setup, Industrial design
Cons: Value and Price, Door compatibility (deadbolt fit)
Door-sense was weakly supported because a reviewer specifically wanted a sensor to know whether the door was open or closed.
Pros: Camera and doorbell performance, Installation and Setup
Cons: Keyway quality, Door compatibility (deadbolt fit)
Door-sense capability was criticized as absent, with a reviewer saying an open/closed door sensor would still be useful despite lock/unlock notifications.
Pros: Value and Price, Installation and Setup
Cons: Keypad, App
Door-sense was a clear weakness where discussed: reviewers wanted an open-door sensor, and one reported the lock throwing the bolt while the door was open.
Pros: Installation and Setup, Value and Price
Cons: Voice control, Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
The main door-sense evidence was negative: the lock can auto-lock without knowing whether the door is actually shut.
Pros: Installation and Setup, App
Cons: Battery, Locking motor
The lock lacks a door-sense feature that reports whether the door is open or closed. This is a clear disadvantage beside the Aqara U400.
Pros: Geofencing, Industrial design
Cons: Feature additions via updates, Key override reliability
Door-sense is a clear weakness in the evidence because one reviewer specifically wanted a sensor to know whether the door was open or closed.
Pros: Palm vein recognition, Installation and Setup
Cons: App, Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
One review flags the lack of open/close detection as a weakness because auto-lock can engage without knowing whether the door is shut.
Pros: Fingerprint, Value and Price
Cons: Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
