Since you already have the linkusb there is no need to change what you
have. Just connect the other devices to the linkusb along with the
existing sensor.
If you did not have the linkusb then us
Piece of cake. You do need a board to solder them to because the package
is so small. This is what I use on my Pis - you can see the DS2483 at
upper left. This board has that white jumper there because I had to cut
a trace:

I've not attempted I2C.
Fear and trembling.

Only the USB bus masters are expensive.
DS2483 I2C master is about a buck.
Multidrop with splitters is the beauty of 1Wire, so take advantage of it!

The beauty of 1Wire is that ALL sensors share lines. Theoretically as
many 1Wire devices as you want can be daisy chained, as they all have
unique IDs. Three wires only required: Data, 5V, GND.
Pinout on 8P8C:
2 +5V DC Power
3 Ground (Green/White)
4 1-Wire Data (Blue)
I have a couple of these
I like the idea of using a splitter.

With the Ethernet splitter are the voltage sensor and temperature sensor
essentially on the same leg?
I have two RaspberryPi with two small 1wire networks but actually know very
little about how this stuff works. I use owfs and python and just grab
current readings from the fuse directory.
Thank
If you want to get fancy and enclose it, anything with terminals will
work. Here's one I made recently for outdoors use:

Otherwise, any stupid splitter is fine:

I have a RaspberryPi with a LinkUSB interface to a voltage sensor.
I want to add a temperature sensor, connected by 150 feet of Cat 5.
I presume I should buy a hub to make life easy.
This 1wire network will never have more than three sensors.
Any hub suggestions?
Thank you,
Peter
