More than 1-Wire interface (SWI) (ex DS24132) discovery and identifications
The simple answer is: it doesn't.

You have to connect those sensors one by one the first time and take notes about their IDs. There are some Onewire chips which allow you to select a few bits of their ID or daisy-chain them for topological enumeration but these are exotic. For most Onewire chips, you have to take notes.
