Ranked #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

Higher ratedRanked #2 in Best Smart Locks

Ultraloq U-Bolt Pro WiFi

4.3

$199as of Apr 22

The Ultraloq U-Bolt Pro Wi-Fi offers exceptional versatility with six unlock methods and built-in Wi-Fi, making it a top choice for keyless entry. However, its utility is slightly hampered by the lack of Apple HomeKit support, reliance on 2.4GHz Wi-Fi, and mediocre battery performance. Despite these limitations, its compact design and robust fingerprint sensor make it a strong asset for most smart homes.

Strengths

— Supports six unlock methods including fingerprint, keypad, key, app, geofence, and Bluetooth
— Built-in Wi-Fi connectivity eliminates the need for a separate bridge or hub
— Compact design fits standard doors with universal backset adjustment (2-3/8" or 2-3/4")

Watch-outs

— Battery life is described as so-so, requiring 4 AA batteries
— Lacks support for Apple HomeKit and Amazon Key integration

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.

Ultraloq U-Bolt Pro WiFi

The Ultraloq U-Bolt Pro WiFi offers the most unlock versatility with six methods, including a robust fingerprint reader that the Schlage Encode Plus and August Wi-Fi Smart Lock completely lack. While it shares the 2.4GHz Wi-Fi limitation with the August, it avoids the Level Lock+'s need for a separate bridge for remote control, though it sacrifices Apple HomeKit support which is a primary selling point for the Level Lock+ and Schlage.
