Update on Kwikset 900 series Z-wave lock controlled by smartthings hub and android App.

I am using this lock with #smartthings hub. I noticed that I can lock it using the smartthings app on my android phone but status is always unlocked. I also noticed that the motor in the lock runs multiple times in bursts to lock. It seems that the motor was struggling because the hole in the frame was not wide enough for the deadbolt to go all the way in. I removed the metal plate, filed the wood and also the metal deadbolt, applied WD-40 and now the deadbolt goes all the way inside in one shot pulse of the motor. The app on the phone shows status is locked correctly.

Hope this helps another user.
