I'm still playing with my setup. Still have a few months before my house is completed. I should have a truck load of ardunio parts on my desk at work on Monday so should be able to start tinkering with UI7. :)

After thinking about it and looking at the lock installation guide i think the best way to detect the lock status would be to create a battery powered door/window sensor. There looks to be plenty of space inside the lock to place a mini and i may be able to piggy back onto the door battery power.
