Does the sensor work just as a basic open/close sensor but fails when used for dry contacts? Or does it fail for both? And what DTH were you using before?
This device has two different ways of sending a closed message, and which it uses, depends on both the parameter settings and the association groups.
It would help to know the current values for parameter one and two as well as the association groups. You can find that out by using Mariano’s Z wave configuration driver. You will have to wake it up in order to get it accept reconfiguration. See the user manual available from the following page:

Here’s the configuration Driver:
The solution may be as simple as adding the hub to both association group one and two. There have been some problems with other stock Z wave edge drivers which were resetting values and not setting the association groups correctly. But I don’t know whether that’s what’s going on here, it just that it might be.
