I have 4 of the new Z-Wave Plus Modules - they are working really well and I never lose connection with the locks (I used to lose connection all the time before I upgraded the locks). I'm using the new Z-Wave Plus Module 2's with the Yale nexTouch Locks (AU-NTB-610-NR). I bought the locks without the module and then ordered the ZW2 modules separately....
Everything works smoothly and you can change all the variables directly in the Vera interface. The Z-Wave Plus makes a huge difference in establishing a reliable connection. in one building, my Vera controller is 3 floors away in a brick brownstone.
