I started it on my ubuntu forum but think others may be interested.
It is 1 revision behind what I'm working on but nearly complete to what I want.
I used one of these http://www.desktopaviator.com/Produc...2040/index.htm
And just got done figuring out how to hook a motion sensor up.
As is I have it text me any time the door has been opened.
I have it wait ten seconds for the door to close and then send me a message. With the current state of the door. When I hook it up to my new house I will also hook up cameras that will take pictures of people entering the house. I will have a tarball and instructions pretty soon but not sure how to post that.
