Hi Paul,
I am running Python, basically what my code does is first to walk
through the directory tree to find all the devices and record their full
path, does that once then it cycles round doing a reads each from each
device in turn using the path it has recorded
try:
sfile = open('device_directory')
val = sfile.read()
except:
log the exception details
The exceptions that I see are 'No such file or directory', but on the
next cycle it could well read that device again. I don't get many for
the I/O boards but temperature sensors I am seeing around 20% failure.
Everything is on the floor in the study, so there are no excessive cable
lengths, all devices are powered.
I will continue to investigate but any suggestions, ideas or theories
would be most welcome:)

Hi Mike And Guy,
I too am using the rpi. I too see no errors in the logs, How are you
detecting no reads. I have 5 ds1820's connected to sleepwalk rpi2.
I'm using http://limings.net/xap/oxc owfs to xap connector. It all
looks to be working, but I'd be interested it exploring it a bit more.
Regards, Paul
