Hi all I am totally new to X10 and trying to work out how to put a very simple light switch together using it. We are just about to change the side a door hangs that goes into my kitchen diner and the current light switch will be behind the door. What I want to do is use a motion detector to turn the lights on when dark when someone enters the room and switch off after 10 mins of no movement. So can someone explain what I need to get to achieve this? Do I just need the motion sensor and an x10 light switch replacement? or do I need more to achieve?
