This lock is 3rd generation and not the 2nd generation which was on sale BF. Third generation Pro version comes with Zwave built in which you can use to integrate with smart hub like smart things which lets you setup rules along with other smart devices as well as operating the lock remotely, August connect hub is not required. I use this lock and it works very good, make sure your deadbolt is compatible here
If it is not compatible you can buy one from list above.
