Followup question on the motorized Zwave deadbolts (Schlage/Kwikset) reporting status: What do these locks report if they attempt to throw the deadbolt and encounter an interference? Do they utilize a limit switch or other feedback to determine that the bolt made it to end of travel? ...Or, do they assume that, since the motor was activated, the deadbolt was successfully engaged?
Like Work2Play, I am using a number of the old Morning Industries deadbolts that cannot report status. I use a proximity sensor in the door frame to determine when the deadbolt is thrown. This works well, and I can determine that all (but one) of my entry doors and sliders are "locked" via the ELK/ISY. Over the years, I have had to adjust the entry doors/strike plates a number of times to eliminate interference due to temperature changes/house settling. It's a fact of life - things age and go out of alignment. The door frame sensor/ELK/ISY has notified me when this occurs and I've been able to correct the situation.
My front entry door has sidelights - Very difficult to add the proximity sensor without some serious mill-work on the jamb. The Zwave deadbolts would be an "elegant" solution if they can determine whether the deadbolt has been "thrown and engaged".
