Hello,
In my previous install I used Z-Wave. But now I’m using HASSbian and I can’t figure out how Z-Wave is installed (or not). The documentation on the website is (I’m sorry) a mess with all the different versions…
Can somebody help me?
Greeting, Ramon
Hi Toby,
Thanks for the quick reply. Yes, I followed the thread. But there is not much about z-wave. Only some folks who can’t get it working like me (as far as I’ve seen).
Gr. Ramon
Can you describe where you’re stuck?
I thought Open-zwave was already installed, but I can’t find it. When I try to install it I can’t figure out where or how to place it.
I’m now trying:
sudo su -s /bin/bash homeassistant
source /srv/homeassistant/bin/activate
pip install --upgrade cython
Still getting an error:
sudo PYTHON_EXEC=$(which python3) checkinstall --pkgname python-openzwave --pkgversion 1.0 --provides python-openzwave
checkinstall 1.6.2, Copyright 2009 Felipe Eduardo Sanchez Diaz Duran

If you’re using the most recent Hassbian image, 1.1 toybox, you’ll just need to run the zwave script that’s built in.
My config simply has
zwave:
usb_path: /dev/ttyACM0
You can find your zwave USB device on pi with $ ls /dev/ttyACM*

@Jeff_VoVillia and all:
RPi3-b; Aeotec Z-Stick gen 5; Aeotec Smart Switch 6.
I am a real newbie at home automation, but a long time programmer. I installed Hassbian from the 1.1 toybox including zwave. The installation went very smoothly but there are several things that are not obvious:
Customized components are put in a subdirectory of .hassbian; the same folder in which configuration.yaml lives. (Let’s call this the hassbian config directory. “HCD”) The 1.1 toybox installation puts this in /home/homeassistant/.homeassistant. I followed the video https://home-assistant.io/developers/ with no success until I discovered this.
ozwcp MUST be run from its installation directory; on my system: /srv/homeassistant/src/open-zwave-control-panel/ . And as has been documented elsewhere, you must stop homeassistant before starting ozwcp.
ozwcp creates a zwcfg_0xXXXXXX.xml configuration file in its installation directory which needs to be shared with homeassistant. In addition, homeassistant z-wave component needs to access various other .xml and .xsd files which (on my system) are located in: /srv/homeassistant/src/python-openzwave/openzwave/config/ .
If you specify a config_path in your zwave: part of configuration.yaml, those .xsd files need to be accessible in that path (I use sym links).
Homeassistant creates a zwcfg_0xXXXXXX.xml and zwscene.xml in the HCD even if they are in zwave: config_path.
I have successfully paired by Smart Switch with my Z-Stick, and it shows up in homeassistant web page. I can control the switch just fine from homeassistant. The problem is that if I switch the Smart Switch manually, the changed state is not reflected in the homeassistant GUI. I can see in the logs that the switch sent an update state info message, that is logged as “UPDATE_STATE_NODE_INFO_RECEIVED”. I think this should trigger some action to query the Smart Switch to determine the current state; but no such activity is logged.
How do I get HA to update its state to agree with the switch?
Thanks for your help; I hope my comments above help others.
Tom
EDIT 2 days later:
I dug into the open-zwave driver to find out what is happening with the message sent from the Smart Switch 6. As documented in the switch docs, a single press of the button is supposed to send an unsecured update info message. Apparently this is used during adding a device to the zwave controller. The zwave driver uses this to update its info about the capabilities of the device if it has not already got the info from the config xml file or the device previously. The only other use is to show that the device is awake. I guess it is only a “side effect” of pushing the button on the switch that it changes the state of the switch.
Bottom line is, the way to synchronize the front end with the state of the switch is to poll the switch.
Thank you Jeff!
I didn’t look on the right place. One simple rule, hours of searching… 
How and where find zwave config_path: for Aeon Labs Z-stick gen5.
Youtube [video](https://youtu.be/ajklDCaOGwY) from Bruh path is
zwave:

config_path: /srv/hass/hass_venv/lib/python3.4/site-packages/libopenzwave-0.3.1-py3.4-linux-armv7l.egg/config
but i can’t find config file in folder ( libopenzwave-0.4.0.31.egg-info ) in my Pi-3

I foolowed this install:
Then:
Then rebooted Pi
thanks 
i will try your following installations, do you have Hassbian on your Pi ?
do you run both commands
$ PYTHON_EXEC=$(which python3) make build
$ sudo PYTHON_EXEC=$(which python3) make install
Yes, Hassbian on Pi3
