Abstract
A smart lock for securing a closure is provided. The smart lock comprises: a drive train for actuating a lock mechanism between a first mechanical end stop and a second mechanical end stop, corresponding to an unlocked position and a locked position or vice-versa; an electric actuator arranged to drive the drive train to actuate the lock mechanism; a position sensor arranged to output a location signal indicative of a position of the drive train; a current sensor arranged to output a current signal indicative of an electrical current flowing through the electric actuator; and a processor. The processor is configured to: control the electric actuator to actuate the lock mechanism in a first direction; monitor the current signal; determine a position of the first mechanical end stop for the lock mechanism based upon the current signal; define a first operational end stop for the lock mechanism, the first operational end stop spaced from the first mechanical end stop; and control the electric actuator to actuate the lock mechanism to stop at the first operational end stop based upon the location signal.
