HomeKit Operation
As with other HomeKit-enabled smart locks, the Yale Assure SL can be controlled via Siri or Apple's Home app for iOS...
Throughout my testing, the lock was responsive to HomeKit commands, with its status showing up quickly in the Home app and quickly locking or unlocking from either Siri commands or the Home app, regardless of whether I was home or away. With a range of HomeKit devices around the house, setting up a "Good Night" scene makes it easy to ensure all lights are turned off, doors are locked, and the garage door is closed before heading off to bed.
