Hello Joe,
thanks for your interest in pyowfs ;)
the .get() and .put() methods can only access attributes of a sensor
object (the leaves in the tree). To access a specific Sensor by id you
have to use the .find() method of the connection. Obviously you should
also check if the sensor actually could be found ...
in my example i started a owserver with fake sensors in another
terminal:
$ owserver --debug -p 4711 --fake=DS2409,DS18S20,DS1921
to access a specific sensor i use the following:
>>> from pyowfs import Connection
>>> c = Connection("localhost:4711")
>>> for s in c.find () :
... print s
...
<Sensor /1F.67C6697351FF/ - DS2409>
<Sensor /10.4AEC29CDBAAB/ - DS18S20>
<Sensor /21.F2FBE3467CC2/ - DS1921>
>>> for s in c.find (id="67C6697351FF") :
... print s
...
<Sensor /1F.67C6697351FF/ - DS2409>
>>> s
<Sensor /1F.67C6697351FF/ - DS2409>
>>> s = c.find (id="67C6697351FF") [0]
>>> s
<Sensor /1F.67C6697351FF/ - DS2409>
>>> s = c.find (id="4AEC29CDBAAB") [0]
>>> s.get ("temperature")
' 14.1603'
>>> s.get ("temperature")
' 60.6969'
>>>

posted this mail also there. see
