|Things should just work - Automagically||
Sonny Vallgren has kindly enough supplied a plugin to run against owserver that brings 1-wire support to the system. However the plugin require that owserver is installed on the system. To do that follow this guide http://wiki.temperatur.nu/
It works both against localy connected hardware as well as an owserver running on a sepparate piece of hardware. (in any case you need to install it to get drivers and such working).
The plugin is available in the repository so if you upgrade you will get it. (If you dont have 1-wire hardware the plugin will not be visible/activated).
To use it just set correct settings and Enable = True for the plugin at the settings page. The you will get signals in for every sensor connected to the system.
I have no such hardware so I havent been able to test this by my self, please report any bugs to me anyhow and I will see what I can do th
