Yes that's working. i will let you know what i've made. I've programmed a
greenhouse control program in perl. Professionally wise i take this project
to learn python. Python is hot these days.

Some time ago I wrote pyownet
https://pyownet.readthedocs.io/en/latest/index.html to overcome some
limitations of the official packages.
The code is quite “stable” now, and does not have some of the fancy new
features of trio-owfs (namely async i/o); however I think pyownet should be
quite straightforward to use.
Some simple suggestion to getting started.
1) Forget python2 (which is pretty dead now): learn and use only python3.
2) Install owserver and owshell
3) First test your setup from a command window with the simple owshell commands
(owdir, owread, owwrite…)
4) Install and activate a python virtual environment
<https://docs.python.org/3/library/venv.html>
5) `pip install pyownet`
6) start the python shell and do some experiments from the command prompt:
import pyownet.protocol
proxy = pyownet.protocol.proxy()
proxy.dir()
['/26.xxxxx0010000/', '/26.yyyyy0010000/']
proxy.read('/26.xxxxx0010000/temperature')
b' 28.3438'
float(proxy.read('/26.xxxxx0010000/temperature'))
28.4062
proxy.dir('/26.xxxxx0010000/‘)
help(proxy.dir)
proxy.dir(bus=True)
['/26.xxxxx0010000/', '/26.yyyyy0010000/', '/bus.0/', '/uncached/',
'/settings/', '/system/', '/statistics/', '/structure/', '/simultaneous/']
It should be quite simple to replicate the owshell commands using the methods
of the proxy object.
Once you are familiar with the owfs structure and the pyownet commands you can
start writing your first script.

Are there any python programmers?
I can read a device with the python-ow pkg, but have any of you an example
python script how to write to a ds2408 forexample?
I'm a really a novice with python, perl is not a problem...
Thanks,
Nico
