Compare eufy Video Smart Lock E330 vs Yale August Smart Lock

Event history is a consistent strength, with multiple reviewers highlighting detailed lock and camera logs that can identify who unlocked the door by fingerprint or code.

Activity and access logs are generally presented as a clear timeline of lock events and users, but one negative review claims a late-night unlock incident did not appear in the log, raising consistency concerns in edge cases.

The Eufy app is broadly praised for setup, live view, quick lock controls, access management, and clear event history, with few complaints beyond battery-related settings tradeoffs.

The app is generally described as intuitive and full-featured (status view, settings, guest management, alerts, and timelines), though one highly negative review reports freezing, connectivity frustration, and inconsistent state reporting.

Auto-lock is widely described as reliable and flexible, with adjustable timers and scheduling, though it is timer-based rather than true door-position sensing.

Auto-lock is consistently praised for flexibility (from very short delays up to about 30 minutes) and for preventing accidentally-unlocked doors, but some users disable it to avoid being locked out when they step outside without phone or keys. Auto-unlock is a high-convenience feature when it behaves, but experiences vary: some reviews say it works well most of the time, while long-term users report it can be slow, inconsistent, or unreliable enough to fall back to physical keys.

Wrong-try protection appears well implemented, letting owners lock out further attempts after repeated bad fingerprints or PIN entries.

The adjustable deadbolt and removable fit pieces help it adapt to common backset and bore variations on standard doors.

Battery life is the biggest unresolved weakness: light use can be respectable, but several reviewers saw much shorter runtimes than the 8-12 month marketing claim once motion, video, and notifications were active.

Battery life is the most common tradeoff: the lock uses two CR123 batteries, and while some sources cite multi-month expectations, at least one long-term review reports significantly shorter life (weeks) and others note higher replacement cost and limited in-app visibility.

Bluetooth helps with setup and is mentioned by some reviewers as an available unlock path, though Wi-Fi and fingerprint are the primary day-to-day methods.

Bluetooth is used for close-range control and proximity-based features (including aspects of auto-unlock), and while it works well for many, some users describe occasional slow or inconsistent proximity behavior.

Build quality is generally rated highly, with reviewers calling the exterior solid, premium-looking, and well made for a lock-camera combo.

Build quality impressions are strong: the compact puck design is described as well-made with a good feel and improved aesthetics compared with older, bulkier generations.

Reviewers generally liked the sharp 2K image, usable night vision, fast live view, and subscription-free local storage, but the camera side remains more compromised than a dedicated video doorbell because field of view, package visibility, and button discoverability can vary a lot by door layout.

Reviews indicate the E330 lacks true door-open and door-closed sensing, so auto-lock relies on timers instead of confirming the door position.

DoorSense/door-position sensing is often cited as useful and accurate for door-ajar alerts when installed and calibrated, but at least one reviewer reports persistent calibration problems and unreliable open/closed status detection.

It fits standard deadbolt doors well, but compatibility gets worse with deep jambs, screen doors, unusual spacing, or layouts that block the camera's view.

Some installations reuse the existing strike plate or fit the current bore cleanly, but others require minor modification or a new strike fit.

Across reviews, the retrofit design is a standout: it replaces only the interior thumb-turn so you can keep your existing deadbolt, exterior look, and physical keys, which is especially appealing for renters and shared access situations.

Fingerprint entry is one of the product's clearest wins, repeatedly described as fast, accurate, and the preferred way to unlock.

Lineup comparisons indicate the E330 does not offer the location-based auto features found on higher-tier Eufy models.

Geofencing underpins the arrival/leave automation and is viewed as helpful by some, but its success depends on the approach path, phone behavior, and Bluetooth handoff, leading to mixed real-world consistency.

Guest access is flexible, with permanent, temporary, scheduled, and one-time code options that reviewers found genuinely useful.

Guest access features are a strong point: reviews describe virtual keys, guest lists, temporary or scheduled access windows, and easy sharing (often via text/email), with keypad entry available as an add-on.

A hub is optional rather than required: the lock works on its own, while HomeBase 3 mainly adds AI features, storage flexibility, and ecosystem extras.

Because Wi-Fi is integrated, reviews emphasize there is no separate hub or bridge required for remote access, simplifying deployment compared with older generations that needed a plug-in module.

Installation is usually quick and straightforward for standard doors, often landing in the 10-20 minute range, though edge cases can require minor door work.

Most reviewers describe a fast install (around 10 minutes) with clear in-app guidance and straightforward calibration, but a minority report setup friction such as app freezes, verification hassles, or door-trim/fitment tweaks that required rework.

The hidden physical key and external USB-C emergency power option give the E330 credible backup access if the battery runs down.

Physical key override remains an important safety net: reviews repeatedly note you can still unlock with a normal key if batteries die or smart features misbehave.

The keypad works well and supports scramble PIN entry, but several reviewers note that the button area can be hard for visitors to find in the dark.

A keypad is available but typically not included; reviewers say it works and is useful for kids or key-free entry, yet it adds cost and some find it small or slightly laggy compared with locks with built-in keypads.

The physical key backup is useful, but the cylinder cannot be rekeyed, which several reviewers see as a practical downside.

Locking and unlocking are generally quick, especially by fingerprint, with several reviewers describing the response as near-instant or sub-second.

Most reviews describe fast, smooth, and quiet lock/unlock action via app or manual turn, though keypad entry can have a small delay and one reviewer reports freezes that interrupt responsiveness.

Limited direct commentary suggests the motor is reasonably quick and quiet, but this is not as heavily discussed as fingerprint speed or battery drain.

The lock mechanism itself is consistently dependable in reviews, with few complaints about failed locking or unlocking once properly installed and calibrated.

Locking reliability is rated highly in most tests after calibration, but a minority report the lock getting confused about state, inconsistent auto-unlock, or requiring occasional troubleshooting to restore dependable operation.

Notifications are a strong point, with repeated praise for fast alerts from motion events, doorbell presses, and lock actions.

Notifications and smart alerts are frequently described as timely and customizable (lock/unlock events, auto-lock events, door-ajar alerts, and user-specific actions), though one account complains about missed logging for a concerning event.

Evidence is limited but positive, including BHMA-related claims and durability figures that suggest a sturdier-than-average smart lock build.

One review cites top-tier physical strength (ANSI Grade 1) for the lock/bolt, framing it as unusually strong among smart locks tested.

Remote locking, unlocking, live view, and answering the door from the app all work well and are central to the product's appeal.

Remote lock/unlock from anywhere is widely reported to be responsive once connected, and even the most critical reviewer notes unlocking via the app itself generally worked; issues center more on setup/state tracking than basic remote commands.

Security features discussed include encrypted connections (Bluetooth and app traffic) and safeguards like voice PIN requirements, contributing to reviewer confidence for typical smart-lock use.

Integration is good but not universal: Alexa and Google are commonly supported, HomeBase 3 adds more capability, and HomeKit support is notably absent.

Smart-home integration is a core strength with support for Alexa, Google, and HomeKit (plus other ecosystems noted in reviews), though HomeKit stability and device state accuracy are not perfect for every user over time.

The touch-sensitive keypad is responsive and modern, though nighttime discoverability is not as polished as on some dedicated doorbells.

Two-factor authentication is explicitly mentioned as available for account access, adding protection for cloud-connected control and sharing features.

User management is robust, supporting admins, shared users, remote passcode assignment, and sizeable limits for codes and fingerprints.

User access management is robust, supporting multiple users (and often multiple homes/locks), with options to tailor alerts and track who used the lock and when.

Value is mixed: the combined lock-camera-doorbell design and no-subscription local storage are appealing, but the price stings more when battery life or fit issues reduce the benefit.

Pricing is often called high but competitive for built-in Wi-Fi smart locks; many justify it for the retrofit convenience, while critics point to CR123 upkeep and occasional reliability hiccups as value detractors.

Voice control through Alexa or Google is commonly supported and useful for basic lock commands, though it is more of a convenience layer than a standout feature.

Voice control works with major assistants and typically requires a PIN/password for unlocking; several reviews report good results, while others mention occasional failures, slowness, or discomfort with speaking a password aloud.

Support and warranty coverage look adequate rather than exceptional, with a one-year warranty mentioned and at least one battery-drain support interaction that did not fully solve the issue.

Weather resistance is generally viewed as solid for outdoor use, with repeated IP65 mentions and positive rain-use feedback, even if one comparison suggested a lower resistance tier than the S330.

Wi-Fi performance is typically stable once connected, with fast remote access and alerts, but setup expects a 2.4 GHz network.

Built-in Wi-Fi is repeatedly highlighted as the key upgrade for true remote control without an add-on bridge, but it can increase battery drain and, in one account, made setup more finicky with certain Wi-Fi environments.
