py-openzwave

What is py-openzwave?

py-openzwave is a python wrapper around the open-zwave c++ project. This allows you to interact with z-wave networks from withing Python.

1. OpenZWave talks to ZWave devices in your house via ZWave PC controller
2. py-openzwave provides python bindings for OpenZWave
3. program your house with Python!

Build instructions for Windows

In order to build py-openzwave on Windows you need MinGW, MinGW is a minimalist GNU compiler for Windows. You can download MinGW here: http://www.mingw.org/ Other requirements are:

• Cython 14.1 or higher, available from: http://www.cython.org
• Open-zwave revision r321 or higher (r321 contains patches for MinGW)

We will assume the following build structure (different structure requires changes in py-openzwave's setup.py!):

\ Root folder -\ py-openzwave source folder -\ open-zwave source folder

1. From the root folder, type "cd open-zwave\cpp\build\windows\mingw32"
2. Enter "make", this will build open-zwave. If all went will you should have an "openzwave.a" file in the "open-zwave\cpp\lib\windows-mingw32" directory.
3. From the root folder, type "cd py-openzwave"
4. Type "python setup.py build --compiler=mingw32", this should build the py-openzwave module. If you are satisfied with the build, you can install it by running "python setup.py install"

Building on Ubuntu

Download and Build

(starting inside the py-openzwave directory)

$ cd ..
$ svn checkout http://open-zwave.googlecode.com/svn/trunk/ open-zwave-read-only
$ cd py-openzwave
$ ln -s ../open-zwave-read-only openzwave
$ patch -d openzwave -p0 < fix_openzwave.patch
$ (cd openzwave/cpp/build/linux; make)

Then the python library:

$ python setup.py build

Now run the test program (change ZWAVE_SERIAL if necessary):

$ python -i test.py

Hints

Building on Ubuntu 10.10 - (drewp@bigasterisk.com)

The 'cython' version for Ubuntu 10.10 is 0.12.1, which is too old. You'll get an error at cdef extern from # "<string>". Removing that cython and running 'easy_install cython' will get you a version at least as new as 0.14.1, which will work.

For the tricklestar USB device, a more robust device name to use is /dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_D-if00-port0 (as opposed to ttyUSB0, ttyUSB1, etc).

I (drewp) still don't know the workflow for adding new devices. For that I used https://code.google.com/p/openzwave-control-panel/ which does have an 'add device' operation.

Adding devices

from the ozcp code,

      setAdminFunction("Add Device");
      setAdminState(
               Manager::Get()->BeginControllerCommand(homeId,
                               Driver::ControllerCommand_AddDevice,
                               web_controller_update, this, true));

then it waits for case Driver::ControllerState_Completed:
