I'm looking at WIKI and as I haven't used many of these types of devices I just don't get how are they supposed to work.
Ok, now I found one image so I can see what is supposed to do: http://www.elektronetshop.de/dokumente/artikel/FotoKlein/00025826_0.jpg
Please correct me if I'm wrong; This device has 9 wires, 4 switches (2 wires each) and ground. Device is battery operated and send low voltage, when any of 4 contacts are connected device sends zwave signal to controller (Core).
So this device could be used so that you any kind of push button connected to it, some examples would be:
* classic wall lighting switch that you connect to it (up to 4 light switches)
* pressure sensor (simple button that would connect when somebody steps on it)
* door or window security sensor (sends signals when doors are open or closed)
Hari have you played with this device?
