Clues on Interfacing simple detection of closed contact?

[bp5]

I can't seem to find a plug and play alarm panel for LMCE so I was going to try to get LMCE to detect a closed contact (maybe using a relay) and use that as an event to signal an alarm condition or movement in a room using a traditional PIR or open door contact. Can anyone give me some clues as to where I might get appropriate hardward and where I can find a template to play with so LMCE will recognize the event?

thanks,
Blaine

you could use a GC-100 http://wiki.linuxmce.org/index.php/Gc100

a little expensive but one way to use relays with LMCE

If you are going EIB/KNX in your automation setup, you can also add a binary sensor. iirc 8-port < 200EUR
