I use RBoy’s DTH and Smartapps to manage my Schlages and it has been working beautifully. The only issue I’ve had is that on very rare occasions, it does not relock when the door has been closed. I haven’t had the time to figure out in what exact situations that happens both due to time constraints and the fact it happens so rarely, but I just went ahead and made a CORE piston that will lock the door if open/close sensor detects closed state for 2 minutes and lock is unlocked. That cleared that right up and no issues since. Love being able to manage codes, change alarm type and sensitivity, etc. all from the SmartThings app or remotely. Might be worth checking out.
