Smart-home integration was a major strength, with reviewers praising Apple Home, Matter over Thread, responsiveness, major ecosystem support, and future-looking compatibility.
Pros: Locking reliability, Lock/unlock speed
Cons: Bluetooth, Physical attack resistance
Smart-home integration was broadly praised, especially Apple HomeKit/Home Key and Alexa routines, though one reviewer noted Matter and Thread were absent.
Pros: Touchscreen, Hub requirement
Cons: Camera and doorbell performance, Door-sense
Smart-home integration was a major strength, especially HomeKit/Home Key and Matter potential, but Alexa setup and Home Key lock limitations created caveats.
Pros: Lock/unlock speed, Fingerprint
Cons: Keyway quality, Wi-Fi
Smart-home integration was strongest for Apple HomeKit and Home Key, while broader ecosystem support was more conditional or dependent on updates.
Pros: Industrial design, Build quality and durability
Cons: Pick/drill resistance (if rated), Keyway quality
Smart-home integration was mostly positive for Alexa, Google, and SmartThings setup, though one reviewer wanted deeper automation.
Pros: Value and Price, Lock/unlock speed
Cons: Existing hardware reuse, Door compatibility (deadbolt fit)
Smart-home integration was a major selling point across reviews, but enthusiasm was tempered by missing Home Key, Home Assistant issues, and model-specific platform limits.
Pros: Weather resistance, User access management
Cons: Locking motor, Remote access
The strongest praise centered on Apple Home Key and broad smart-home support, with reviewers calling Home Key fast and convenient, especially for iPhone and Apple Watch users.
Pros: Locking reliability, Lock/unlock speed
Cons: Weather resistance, Door-sense
Smart-home support is a major selling point, with praise for HomeKey, HomeKit, Matter, Alexa, Google, and broad ecosystem flexibility, tempered by hub/Bluetooth tradeoffs.
Pros: Access logs, Value and Price
Cons: Warranty and support, Wi-Fi
Smart-home integration was broad and useful across Alexa, Google, IFTTT, SmartThings, and routines, but HomeKit, Amazon Key, and 2.4 GHz setup limits created tradeoffs.
Pros: Locking reliability, Build quality and durability
Cons: Two-factor authentication availability, Backset compatibility
Smart-home integration was broad and often praised across HomeKit, Alexa, Google, Matter/module plans, and other ecosystems, though Home Key and Android/Wear OS gaps created caveats.
Pros: Lock/unlock speed, Guest Codes and Access
Cons: Backset compatibility, Warranty and support
Smart-home integration was mixed-positive: Alexa, Google, Apple Watch, and Eufy ecosystem links were appreciated, but lack of HomeKit hurt one review.
Pros: Lock/unlock speed, Security features (encryption)
Cons: Door-sense, Keyway quality
Smart-home integration was broad and often praised, but Alexa/Google setup hitches, HomeKit offline issues, and one severe HomeKit complaint made reliability mixed.
Pros: Locking motor, Physical attack resistance
Cons: Fingerprint, Battery
Smart-home integration is broadly supported across Matter and major platforms, but several reviewers found third-party control limited or messy.
Pros: Lock/unlock speed, Wi-Fi
Cons: Feature additions via updates, Warranty and support
Smart-home integration was useful with Alexa, Google, Ring, Amazon Key, and Home Assistant, but limited by HomeKit, IFTTT, SmartThings, Google unlock, and Ring Alarm gaps.
Pros: Bluetooth, Hub requirement
Cons: Door-sense, Fingerprint
Smart-home integration was useful but ecosystem-dependent: Z-Wave, SmartThings, Wink, Alexa, and other platforms worked well in some cases, while HomeKit and Google limitations hurt compatibility.
Pros: Existing hardware reuse, Build quality and durability
Cons: Weather resistance, Locking motor
Smart-home integration was powerful but mixed: Matter, Apple Home, Home Assistant, and automations worked well for some, while others had unreliable or basic Matter behavior.
Pros: App, Battery
Cons: Geofencing, Jam detection
Smart-home integration was useful with Alexa, Google, SmartThings, and Hue, but reviewers repeatedly flagged missing or delayed HomeKit/Matter support.
Pros: Key override reliability, Remote access
Cons: Warranty and support, Bluetooth
Smart-home integration was the most split area: basic Matter, Alexa, Google, and HomeKit control worked, but advanced lock, camera, and palm features often stayed inside Eufy.
Pros: Lock/unlock speed, Locking reliability
Cons: Door compatibility (deadbolt fit), Hub requirement
Smart-home integration is mixed: the lock fits Wyze well and supports common assistants, but limited third-party support and missing Matter/HomeKit remain caveats.
Pros: Lock/unlock speed, Keypad
Cons: Door-sense, Battery
Smart-home integration was mixed because Alexa/Google support was useful, but reviewers noted the lack of Apple HomeKit, IFTTT, or Matter.
Pros: Lock/unlock speed, Wi-Fi
Cons: Jam detection, Door compatibility (deadbolt fit)
Smart-home integration was the main limitation: Alexa and Google were supported, but reviewers missed HomeKit, Matter, IFTTT, or broader security-system support.
Pros: Feature additions via updates, Locking reliability
Cons: Door-sense, Auto-relock after failed attempts
Smart-home integration was the biggest tradeoff: Nest ecosystem integration helped, but limited Alexa, HomeKit, SmartThings, IFTTT, and non-Nest support hurt flexibility.

Cons: Door-sense, Bluetooth
Smart-home integration was a recurring weakness despite Alexa and Google support because reviewers wanted HomeKit, IFTTT, security-system, and doorbell integrations.
Pros: Lock/unlock speed, Locking reliability
