python-openzwave

python-openzwave is a python wrapper for the openzwave c++ library : https://github.com/OpenZWave/open-zwave

  • full manager implementation with options
  • an API to map the ZWave network in Python objects
  • a command line manager to manage / debug your ZWave network
  • a full-event webapp example : flask + socket.io + jquery
  • a suite of tests
  • many examples
  • Full documentation

python-openzwave 0.4.x is here !!!

  • New installation process via pip

  • First, you need some build tools and libs. On ubuntu, you should use :

    sudo apt-get install --force-yes -y make libudev-dev g++ libyaml-dev

  • Make your virtualenv and activate it :

    virtualenv --python=python3 venv3
source venv3/bin/activate

  • Install the default flavor :

    (venvX) pip install python_openzwave

  • The previous command try to install python_openzwave with the flavor 'shared'. If it can't find a precompiled library of openzwave, it will use the flavor 'embed' with sources downloaded from https://github.com/OpenZWave/python-openzwave/tree/master/archives. You can change this using flavor option. There is a bug in the package dependencies and flavors on some systems. You may need to install dependencies manualy :

  • on python 2.7 :

    (venvX) pip install cython wheel six
(venvX) pip install 'Louie>=1.1'

  • on python 3 :

    (venvX) pip install cython wheel six
(venvX) pip install 'PyDispatcher>=2.0.5'

  • Choose your flavor :

    • embed : the default one. Download sources from https://github.com/OpenZWave/python-openzwave/tree/master/archives and build them. Python_openzwave is statically build using a cythonized version of libopenzwave. No need to install cython.
    • shared : if you have install openzwave as module manually, you can link python_openzwave to it.
    • git : download sources from openzwave github and link statically to it.
    • embed_shared : download sources from https://github.com/OpenZWave/python-openzwave/tree/master/archives, build and install as module on the system. Python_openzwave use it. Need root access to install openzwave libs.
    • git_shared : download sources from openzwave github, build and install them as module on the system. Python_openzwave use it. Need root access to install openzwave libs.
    • ozwdev and ozwdev_shared : use the dev branch of openzwave on github.
    • dev : for python_openzwave developers. Look for openzwave sources in a local folder specified by the LOCAL_OPENZWAVE environment variable (defaults to 'openzwave').

  • Install it :

    (venvX) pip install python_openzwave  --no-deps --install-option="--flavor=git"

  • You can update to the last version of openzwave using the git flavor :

    (venvX) pip uninstall -y python_openzwave
(venvX) pip install python_openzwave --no-cache-dir --no-deps --install-option="--flavor=git"

  • At last, you can launch pyozw_check to test your installation :

    If no usb stick is connected to the machine, launch :

    (venvX) pyozw_check

    If you've one, use it for advanced checks :

    (venvX) pyozw_check -i -d /dev/ttyUSB0

  • The old manager is now available via the pyozw_shell command. You need to install module "urwid>=1.1.1" with pip before using it.

  • libopenzwave and openzwave python modules are packaged in the python_openzwave. So developers needs to update their install_requires (it works fine with pyozw_manager). They can use the following code to update softly :

    pyozw_version='0.4.1'

def install_requires():
    try:
        import python_openzwave
        return ['python_openzwave==%s' % pyozw_version]
    except ImportError:
        pass
    try:
        import libopenzwave
        return ['openzwave==%s' % pyozw_version]
    except ImportError:
        pass
    return ['python_openzwave == %s' % pyozw_version]

  • If you already have an 0.3.x version installed, you should update your installation as usual. Don't install it with pip as it can break your installation (maybe not if you don't remove old modules)

  • Support for windows, macosx, ... is not tested. Feel free to report bug and patches. We can try to support these plateforms. Don't have Windows at home so I can't help. Same for mac.

  • Old installation process is deprecated and reserved for python-openzwave-developers and alternatives machines.

  • Please report your successful installations here : OpenZWave#73
