An electronic device associated with a lock device obtains a number of users detected within a premises, and detects a trigger event related to a lock device and premises. When the trigger event is detected, a target state of the lock device is determined based on: (1) the number of users within the premises, (2) user security profiles indicating a desired target state of the lock device when a respective user is within the premises, (3) locations of detected users; (4) user states of detected users indicating whether the respective user is asleep or active; and/or (5) a current premises mode, including an armed state and a disarmed state. A current state of the lock device is determined, and if the current state and the target state of the lock device are not the same, instructions are provided to the lock device based on the target state.
