1. August Smart Lock: Minimalism, Intelligence, and Convenience Without the Hassle
The August Smart Locks is one of the most popular smart lock models in the world. Its biggest advantage is easy installation without replacing the existing lock or handle. It simply attaches to the inside of your door, preserving the external appearance of the lock and key — ideal for rentals or condos where modifying door hardware is restricted.
🔧 Installation & Integration
Installing the lock takes around 10–15 minutes, and even someone who’s never held a screwdriver can manage it. No drilling, no wiring. All you need to do is remove the inner side of your current lock and attach the August unit in its place. Everything you need is included in the box.
Once installed, the lock is configured via the August Home app (iOS / Android). From unboxing to full functionality — the process takes about 20 minutes.
📲 Smartphone Controls & Features
- Auto-lock & unlock: The door unlocks when you approach and locks when you leave.
- Virtual keys: Grant temporary or permanent access to friends, family, or delivery people (e.g., for one evening or a week).
Push notifications: See who entered and when, and track whether the door is locked or open.
Voice assistant integration: Works with Amazon Alexa, Google Assistant, Apple HomeKit. Just say “Siri, unlock the door” — and it listens.
Automation support: Set up routines — like auto-locking at 10 PM or triggering other smart devices when you leave home.
🔋Power & Battery Life
Runs on two standard CR123 batteries (depending on the model). One set lasts around 4–6 months, and the app notifies you in advance when it’s time to replace them. Bonus: these batteries are easy to find in any store.
🔐 Security & Encryption
August uses 256-bit AES encryption (like banking apps) and two-factor authentication. This means your access credentials can’t be easily intercepted over Bluetooth or Wi-Fi.
Every action is logged in an activity journal, and virtual keys can be revoked instantly. You can also manually lock or unlock the door remotely, even from thousands of kilometers away.
❌Things to Consider:
The lock does not have a built-in keypad — if your phone isn’t available or is dead, you’ll need the optional August Keypad sold separately.
It relies on Bluetooth or Wi-Fi (with the Wi-Fi Bridge) — occasional delays may occur if the signal is weak.
Because it’s an overlay-style lock, the door still appears “traditional” from the outside — meaning no one can tell you’re using a smart lock.
