Product specification sheet for the August Smart Lock Pro (ASL-03) — a Z-Wave and Bluetooth retrofit smart lock designed for professional installers.
The August Smart Lock Pro is a Z-Wave Plus retrofit smart lock that gives homeowners full control of their front door. Homeowners can lock and unlock the door, grant keyless entry to family and friends, and monitor who comes and goes — all from their iOS or Android phone. It attaches directly to the existing deadbolt, so homeowners can continue using their existing keys. Installation takes less than 10 minutes and requires only a screwdriver.
