There are a number of hubs that support "star" topology including
EDS OW-SERVER-ENET and OW-SERVER-WIFI
LinkHUB
HobbyBoards Hub
DS2482-800
And some in development that I can't disclose.
In general, these hubs have 3,4 or 8 channels that are electrically
independent but logically combined. (Actual

It's discontinued, so usual distributors don't list it anymore. You have
to ask around who has still stock. I bet there are millions somewhere
out there waiting to be used. Don't know where at

As a rule of thumb, I once worked out/said: 100 meters (total line
length) and 20 sensors as fully save.
Using a DS9490 (DS2490 chip).
More is surely possible, using DS1

Why don't you use the DS2482-800 as busmasters?, then you can make a
hub for a star configuration.
like i did on http://fstab.nl/en/beaglebone, it will work also for the

Jan,
your're using Ethernet-Hubs to distribute 1-Wire??
Check your HW, I guess this is nothing to blame owfs with..
