for two cases.
I am starting owserver like this:
owserver --debug -c /etc/owfs/owfs.conf --timeout_volatile 300
--error_print 0 --error_level 7 --nozero -p 4305
And owfs like this:
owfs --debug --allow_other -C -s localhost:4305 /owfs2

I forgot to include debugging output from owserver's startup. There's a
Duplicate family entry: rtd_family that looks suspicious.

Please keep us posted on this as it's a very important topic.

(the developer behind the Moteino) is very knowledgeable and might
be able to provide some guidance. Also, there are a few projects he's
done that are mentioned on his blog. Some of these might provide an idea
of how to approach the problem.

you (the RPi) talks to the uC
and the uC talks to the RFM. On the other side (remote sensor side) the
uC only talks to the RFM.
I guess I'm missing something...

Hi Colin
using USB and
talk to it through some serial communication protocol that you come up with.
Felix apparently has the Moteino-USB, which comes with an USB interface.

I'll start off with the bitbanging and see if I can't find a way to get
a DS2483 and the AVR talking.
