[mh] 1-wire / ibutton howto for mh on linux ?

[declang <de...@de...>]

Hi,
This 1-wire stuff is very interesting and I've been busy googling for info
on using it with misterhouse.
Haven't had much success, so I'll ask here :)

I intend to add quite a number of temperature sensors - probably 15 to 20
sensors.
I'd hope to be able to store all these temperatures for graphing, etc and
have some sort of control of my heating system based on the recorded
temperatures from specific rooms.

Whats my best way to go about this ?
Is there a particular model of ibutton device I should be looking for ?
What hardware do I need at the pc end ? Simply the USB interface ?  Is this
linux compatible ?

Is it wise/unwise to run all these sensors off one cable run, or should I
split it up into several runs, (or mabye run a cat5 cable & use 4 different
pairs).  From my limited understanding, I simply run a 2-wire cable from my
PC and loop around each and every room where I want to place a sensor. If I
have to run a cable, I could run a cat5 cable and use different pairs fro
different groups of sensors, but then I'd need a number of usb modules to
plug each cabel pair into ? Or am I understanding it correctly ?

I've read about some time delays in mh, getting the data from the sensors,
so should I be using some sort of capture program to capture to a data file
& have mh read this data file ?
