AFAIK it is not possible in OW-Python to access “subdirectories”.
You can try pyownet, http://pyownet.readthedocs.io/en/latest/ which I wrote to
overcome this limitation:
#! /usr/bin/env python2
from pyownet import protocol
owp = protocol.proxy('localhost', 4304)
for sensor in owp.dir():
if owp.read(sensor + 'type') != 'BAE':
continue
print sensor, owp.read(sensor + 'version'), owp.read(sensor + '910/count')
(BTW if this is a new project, I would suggest using python3 instead of python2)
