Ron Klinkien has set up a Wiki called MisterHouse from Scratch, where he describes his experiences with setting up the Home Automation software MisterHouse.
He describes all the steps he had to take, the tips and tricks he learned along the way, and a lot of under-the-hood details on how to configure Linux, MisterHouse and several accessories he attached to his Home Automation box.
A very interesting read for anyone interested in Home Automation, and a must for anyone setting up MisterHouse.
