August Smart Lock Pro + Connect

The August Smart Lock Pro with Connect Wi-Fi Bridge is a retrofit smart lock that attaches to the inside of your existing deadbolt, preserving your exterior hardware and keys. This lock provides comprehensive smart home integration including Apple HomeKit, Amazon Alexa, Google Assistant, and Z-Wave Plus compatibility. The included Connect bridge enables remote access from anywhere.

The lock auto-unlocks when you arrive home using phone GPS and auto-locks after you leave. DoorSense technology detects whether the door is actually closed before engaging the lock. The battery-powered motor attaches to your existing thumbturn, meaning external appearance remains unchanged and existing keys continue working.

With Z-Wave Plus support, the lock integrates with SmartThings, Hubitat, and other Z-Wave controllers in addition to WiFi platforms. The August app provides guest access management, activity logs, and detailed access scheduling. For renters or homeowners who can't replace exterior hardware, the Pro + Connect provides the most comprehensive ecosystem support available in a retrofit lock.
