One Wire Introduction

Nice: I have a lot of old 1-wire stuff laying around from when I was developing my own HA program. I was using the IDs for door keys and opening the garage when the kids got home. I would like to get something running under HS. Does any one have a plug-in that returns the ID off the iButton? It would be nice to return the data that is in the iButton as well (ie. if it is a thermal button it would be able to get the data from it.) I started to install this one but it didn't go smooth and I'm fighting HSTV install now. Don't Want to fight another at this time.
