August Wi-Fi Smart Lock (4th Gen)
Best OverallPros
- No separate hub required for remote access
- Compact design fits most deadbolts
- DoorSense reliably detects open/close status
Cons
- Requires stable Wi-Fi signal
- Battery drain can be faster with heavy use
The August Wi-Fi Smart Lock (4th Gen) is the most refined smart lock from the brand. It connects directly to your home Wi-Fi network, eliminating the need for a separate Connect bridge. This makes setup simpler and ensures you can lock or unlock your door from anywhere using the August app.
Owner reviews consistently praise the reliable DoorSense technology, which accurately tells you if your door is open, closed, or locked. The lock fits over your existing deadbolt, so you keep your original keys. Battery life is rated at around six months, though this can vary based on usage and Wi-Fi signal strength.
August Smart Lock Pro (3rd Gen)
Best Budget ValuePros
- Lower price point than 4th Gen
- Z-Wave compatibility for smart home hubs
- Works with existing deadbolt
Cons
- Requires August Connect bridge for remote access
- DoorSense can be less accurate on some doors
The August Smart Lock Pro (3rd Gen) is a solid choice if you want to save money while still getting premium features. It uses Z-Wave and Bluetooth for connectivity, which means it can integrate with smart home hubs like Samsung SmartThings or Wink.
To access the lock remotely, you will need the August Connect Wi-Fi bridge, which is often sold separately. Many owners report that the lock itself is very reliable, and the ability to use your existing key is a major plus. The battery life is consistent with the 4th Gen, lasting around six months.
August Smart Lock (2nd Gen)
Best Basic ModelPros
- Lowest cost option in the lineup
- Simple installation with no wiring
- Auto-lock and auto-unlock features
Cons
- No remote access without Connect bridge
- Limited range due to Bluetooth only
The August Smart Lock (2nd Gen) is the entry-level model that still delivers core smart lock functionality. It connects via Bluetooth, so you can lock and unlock your door when you are within range, typically around 30 feet.
This model is best for apartment dwellers or those who do not need remote access. It supports auto-lock and auto-unlock based on your phone's proximity. Owner reviews note that it is very reliable for local use, but you will miss out on the convenience of checking your lock status from work without the extra Connect bridge.
August View Doorbell Cam
Best Video SecurityPros
- Integrated doorbell and camera
- Works with August app for unified control
- Clear 1080p video with night vision
Cons
- Requires subscription for cloud storage
- Battery life is shorter than dedicated locks
The August View Doorbell Cam adds a visual layer to your smart alarm system. It features a 1080p camera with a 140-degree field of view, two-way audio, and night vision. You can see and speak to visitors directly from the August app.
This device can be hardwired or run on battery, giving you flexibility in installation. Owner reviews highlight the clear video quality and the convenience of having your doorbell and lock in one app. The main downside is that cloud storage for recorded video requires a monthly subscription.
August Keypad + Connect Bundle
Best Full EcosystemPros
- Provides keyless entry for guests
- Connect bridge enables remote access
- Long battery life on keypad
Cons
- Bundled price is higher than lock alone
- Keypad can be less weather-resistant
The August Keypad + Connect Bundle is the complete package for those who want full control. It includes the August Wi-Fi Smart Lock (4th Gen), the August Keypad for keyless entry, and the August Connect bridge for reliable remote access.
This bundle is ideal for families who want to give access codes to guests, cleaners, or dog walkers without sharing a physical key. The keypad mounts on your door frame and uses a long-lasting battery. Owner reviews appreciate the convenience, though some note the keypad can be affected by extreme weather conditions.
What to check before buying an August Smart Alarm
Before you purchase an August smart alarm, verify your door's compatibility. August locks are designed to fit standard US deadbolts, but they may not work with all European or non-standard locks. Measure your door's thickness and the backset distance to ensure a proper fit.
Also consider your home's Wi-Fi network. The 4th Gen lock requires a 2.4 GHz connection, while older models may need a separate bridge. Check the signal strength at your door location to avoid connectivity issues. Finally, decide if you need remote access, as this will determine whether you choose the 4th Gen or a bundled kit with the Connect bridge.
Mistakes to avoid with August Smart Alarms
A common mistake is ignoring battery alerts. August locks use four AA batteries, and the app will notify you when they are low. Replace them promptly to avoid being locked out. Another error is installing the lock without calibrating the DoorSense sensor, which can lead to false open/close readings.
Do not assume all August locks work with every smart home platform. The 3rd Gen Pro uses Z-Wave, while the 4th Gen uses Wi-Fi. If you have a specific hub like SmartThings or HomeKit, verify compatibility before buying. Finally, avoid using rechargeable batteries, as they can cause inconsistent performance and shorter battery life.
