How to monitor if a deadbolt is locked using z-wave?

Using INSTEON it appears I would be able to monitor the deadbolt using a TriggerLinc.

What is the equivalent for the z-wave network?

Thanks

Get a ZWave lock?

I am trying to do this with an old "dumb" dead bolt.

Anyway I do not believe that a z-wave lock will tell you if the door is locked in the door jamb. For all it knows, the door my be wide open and locked.

Thanks

That's true - I use a DS10A in tandem with my Kwikset lock so I know the door is both closed and locked.

You could always install a plunger contact in the slot where the deadbolt rests when locked.

With the Kwikset locks, they send a confirmation that they have locked/unlocked back to the controller. If there is a door jam or failure to lock the Kwikset will not send this confirmation and the lock will not change statuses on the controller. Depending on the controller you are using you can setup a rule to repeat the lock command or to notify you in the event of a failure.

I believe most z-wave deadbolts allow for monitoring of a deadbolt's status via instant feedback and polling. However, I can only confirm that you can do this with a Kwikset z-wave deadbolt and a VRC0P+3 (v3) RS232 z-wave controller.

Here's an open-source driver me and a few cocooners worked on:

The driver uses Premise which is also free.

Z-Wave support is added when someone buys a new Z-Wave device type, but there is a large number of devices that are currently supported. I did all of the code for the Z-Wave locks and tested it thoroughly (I use my setup everyday), but it is without warranty. The price is right though

I do something similar too. Since my alarm automatically locks the doors when armed, I found that sometimes I would be exiting a door and the deadbolt would lock, doh! I added logic to ensure the door was closed (via magnetic reed switch) before locking it; if the door isn't closed a timer is set to again check if the door is closed in x seconds and if it is lock it.

+1 for replacing with a z-wave lock. Just make sure you can get the status and not just control it. The schlage lock is a better design IMHO since it doesn't actually use a motor to retract the deabolt, but just releases it. A lot easier on the batteries. Plus Schalge is a better brand than Kwikset. Looking at getting some of these myself.

This Idea of a plunger contact + DS10A would work. For more zwave goodness wire the plunger contact to one of these
