Higher ratedRanked #3 in Best Smart Locks

August Wi-Fi Smart Lock (4th Generation)

4.2

$200as of Apr 22

The August Wi-Fi Smart Lock (4th Generation) offers a remarkably easy installation process and reliable smart home integration, making it a solid choice for automating door security. However, its utility is limited by the lack of 5GHz Wi-Fi support and the absence of a built-in keypad, which can be problematic if a user is locked out without their phone. While the auto-lock features work well, the device's high standard retail price and bulky design may deter some buyers unless purchased on sale.

Strengths

— Super-simple setup that can be completed in minutes using a screwdriver
— Seamless integration with Alexa, Google Assistant, and HomeKit
— Reliable Auto-Lock and Auto-Unlock features triggered by phone proximity

Watch-outs

— Does not support 5GHz Wi-Fi connectivity
— Lacks an alternate unlock method if both keys and phone are left inside
— Physical unit is described as bulky or 'chonky' despite size reductions

How they stack up

August Wi-Fi Smart Lock (4th Generation)

While the August Wi-Fi Smart Lock (4th Generation) offers a simpler setup than the Schlage Encode Plus and a more compact footprint than the bulky Ultraloq U-Bolt Pro, it falls short by lacking a built-in keypad, a feature the Yale Assure Lock 2 and Ultraloq provide for keyless entry without a phone. Its reliance on 2.4GHz Wi-Fi mirrors the Ultraloq's limitation, but unlike the Yale, it does not support the newer Thread protocol for future-proofing.

Yale Assure Lock 2

The Yale Assure Lock 2 distinguishes itself from the August and Level Lock+ by offering a built-in backlit keypad and support for Thread connectivity, though it suffers from inconsistent Wi-Fi performance that the Schlage Encode Plus and Ultraloq U-Bolt Pro handle more reliably with integrated hubs. Its battery life is notably shorter than the Ultraloq's when using Wi-Fi features, and it lacks the Level Lock+'s discreet, hidden-motor design.
