Aqara Smart Lock U100 Fingerprint Deadbolt, Gray (SDL-D01) vs August Wi-Fi Smart Lock, 4th Generation, Silver (AUG-SL05-M01-S01)

These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.

Aqara Smart Lock U100 Fingerprint Deadbolt, Gray (SDL-D01)

Apple households already running an Aqara Zigbee hub

A fingerprint and keypad deadbolt with Apple Home Key, NFC card support and a mechanical key, running on four AA batteries with a USB-C emergency port. Bluetooth and Zigbee do the talking, so remote access and voice control need an Aqara hub, and the manual lists no Thread or Matter.

Published specifications

  • Maker: Zigbee 3.0, Bluetooth 5.0 and NFC; no Wi-Fi listed in the manual
  • Maker: Aqara Zigbee 3.0 hub required for remote and voice unlocking
  • Maker: door thickness 35-55 mm; backset 2-3/8 in or 2-3/4 in
  • Maker: up to 50 fingerprints, 75 passwords, 50 accounts
  • Maker: four AA batteries, eight months average in Aqara's own test
  • Maker: front panel IP65; the indoor panel is for indoor use only

Strengths

  • Apple Home Key works from an iPhone or Apple Watch after HomeKit setup
  • USB-C emergency port on the outside plus two mechanical keys
  • Phantom passwords let you pad a code to twenty digits against onlookers

Caveats

  • Remote access and voice control need an Aqara hub that is not included
  • Apple Home only setup disables fingerprint recognition and auto-lock
  • Listing title says Matter over Thread; the manual lists neither

August Wi-Fi Smart Lock, 4th Generation, Silver (AUG-SL05-M01-S01)

Renters and anyone who wants to keep their existing keys

A retrofit that swaps only the interior thumbturn, leaving your deadbolt, your exterior hardware and your keys untouched. It brings Wi-Fi, app-shared access, Auto-Lock and a DoorSense sensor. August states in its own warranty that the device is not an ANSI or BHMA certified lock and must be used with one that is.

Published specifications

  • Maker: fits over most single-cylinder deadbolts; compatibility list published
  • Maker: exterior of the door is unchanged, existing keys keep working
  • Maker: requires 802.11 b/g/n 2.4GHz Wi-Fi and an August app account
  • Maker: CR123 batteries supplied; no battery-life figure published
  • Maker: DoorSense sensor, adapters, cover plate and tape in the box
  • Maker: one-year limited hardware warranty, US and Canada only

Strengths

  • Keeps your existing keys and leaves the outside of the door unchanged
  • DoorSense sensor is in the box, listed alongside Auto-Lock on the listing
  • Installs with a screwdriver on the inside face, no drilling of the door

Caveats

  • August states the device is not an ANSI or BHMA certified door lock
  • No exterior keypad or reader, so guests need a key or the app
  • Setup needs an account and a 2.4GHz network; no 5GHz support is stated
