I have an identical setup with three Schlage and I use custom device handlers and smartapps to control them. If you aren’t using it now, I would highly recommend @Rboy because it simply works and his support is top notch almost to a fault. Don’t let the small fee he is asking stop you like it did me at first because you get access to his library of apps. One of my favorite features is being able to maintain one smartapp for the user codes that automatically syncs up all three plus any valid user code disarms the ST security function.
