it may sound sily, but in your examples you are reading a different
counter-chip in each case. Is it ok ?

Hi all,
I'm tinkering around with ownet in python (which I like very much,
bravo), and I have a situation I don't understand.
I'm trying to read a rain gauge which is a counter, connected via usb to
a nslu2 (owserver 2.6p2)
From a Debian Etch machine (owread 2.6p0)
/opt/owfs/bin/owdir -s 10.0.0.10:3002 /1D.F8B405000000/
/1D.F8B405000000/address
/1D.F8B405000000/counters.ALL
/1D.F8B405000000/counters.A
/1D.F8B405000000/counters.B
/1D.F8B405000000/crc8
/1D.F8B405000000/family
/1D.F8B405000000/id
/1D.F8B405000000/locator
/1D.F8B405000000/memory
/1D.F8B405000000/mincount
/1D.F8B405000000/pages
/1D.F8B405000000/present
/1D.F8B405000000/r_address
/1D.F8B405000000/r_id
/1D.F8B405000000/r_locator
/1D.F8B405000000/type
and...
/opt/owfs/bin/owread -s 10.0.0.10:3002 /1D.F8B405000000/counters.A
206666
That works fine.
From python on the same machine
>>> import ownet
>>> s=ownet.Sensor("1D.438101000000","10.0.0.10",3002)
>>> print getattr(s,'counters.A')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "usr/lib/python2.4/site-packages/ownet/__init__.py", line 254, in
__getattr__
AttributeError: counters.A
furthermore..
>>> print s._attrs
{}
Any ideas ?
Thanks
Matt
