Folks - update your smart lock firmware - the lock is fixed!!
Yesterday they rolled out new firmware for the smart lock. Now the calibration routine tests both ends of the throw (locked and unlocked), and it made three throws during the process (unlock, lock, unlock)! Now my lock is no longer jamming up when I use the manual knob, and for probably the first time ever it was perfectly dialed in with a a single calibration.
This is what I have been waiting for. I have been a smartlock user since it came out, but the bad calibration routine was always disappointing and left my lock knob jammed a little after some time even though the install and the deadbolt itself is perfect. It kept me from wanting to use it on other doors in my house.
If this holds up, I will be getting more of these finally.
