August Wi-Fi Smart Lock (4th Gen)

The August Wi-Fi Smart Lock 4th Generation is a compact retrofit lock with built-in WiFi, eliminating the need for a separate bridge. This smaller design fits more doors than previous generations while providing remote access directly through your home network. The lock preserves your existing exterior hardware and keys while adding smartphone control.

Auto-unlock detects your arrival via phone location and unlocks as you approach, while auto-lock secures the door after you leave or after a configurable delay. DoorSense confirms the door is closed before locking. The August app provides guest access with scheduling, activity history, and integration management.

The 4th Gen lock works with Amazon Alexa, Google Assistant, and Apple HomeKit for voice control and smart home automation. The built-in WiFi simplifies setup compared to bridge-based systems. For users wanting straightforward retrofit smart lock functionality with mainstream ecosystem support, the 4th Gen delivers essential features in a smaller, self-contained package.
