Full review
Longer notes from the same comments we summarized above.
What people reported
Many owners found the August Wi-Fi Smart Lock (4th Gen) easy to install, noting that it works by replacing only the interior portion of an existing deadbolt, which means the security of the original deadbolt and cylinder remain unchanged. Some users appreciated its convenience and HomeKit compatibility. The ability to grant remote access with custom schedules was also mentioned as a positive feature.
Problems people mention
Wi-Fi connectivity is a major and recurring problem for many. Owners report frequent disconnections and difficulties getting the lock to connect reliably to 2.4GHz networks, especially with mesh Wi-Fi systems. This often defeats the purpose of a Wi-Fi-enabled smart lock. Battery life is another significant drawback, with numerous reports of CR123 batteries lasting only a month or up to three months maximum, leading to frequent and costly replacements.
The August app itself is a frequent source of frustration. Some iOS users reported the app failing to launch or losing connection to the lock. Others experienced a "circular logic" problem where the app required connection to reset the lock, but only allowed reset if connected. Customer support is widely criticized, described as "nonexistent," "agonizing," and "terrible," with users reporting lost case history and unhelpful AI-driven responses. Some users also experienced slow or unreliable auto-unlock functionality, and compatibility issues with specific deadbolt types (e.g., key-turn only inside) or DoorSense calibration problems. One user described an "epic" year-long struggle to get the lock working, ultimately throwing it away.
Where owners disagree
While many found installation straightforward, one owner mentioned having to drill a new hole for the lock. There's also some disagreement on overall satisfaction; some users found the lock convenient and secure enough, while a significant number expressed extreme disappointment due to persistent technical issues.
Who it's for
This lock might appeal to those seeking a smart lock that works with existing deadbolts and offers remote access. However, given the widespread and critical issues reported with Wi-Fi reliability, battery life, app functionality, and customer support, it is best suited for users who are very patient, technically proficient in troubleshooting network issues, and willing to frequently replace batteries or explore rechargeable options. Buyers should be aware of the potential for significant setup and ongoing reliability challenges.
