Help with openzwave and virtualenv

Configuration
1

Hello, I will preface this by saying I am not a Linux expert. I can fight my way around with some guidance but when a tutorial doesn’t go exactly as planned it’s off to Google… but I haven’t found much for this one.

I am using VMware on my home server to run HA (and other things). I have an Aeotec ZWave USB stick passed through to the HA VM. It is seen as /dev/ttyACM0 so I believe that part is OK.

HA is installed on Debian 8.5.0 x64 in a virtualenv via the guide on the site. It autostarts (with the guide on the site’s help) and that works fine. I also setup openzwave (from within the virtualenv) with the guide but it does not work.

The relevant section in my configuration.yaml is:

zwave:
  usb_path: /dev/ttyACM0
  config_path: ./python-openzwave/openzwave/config/
  polling_interval: 60000
  customize:
    sensor.greenwave_powernode_6_port_energy_10:
        polling_intensity: 1

That directory seems to contain all the right openzwave stuff?

admin@debian:/$ ls ./python-openzwave/openzwave/config/
    2gig                      domitech             frostdale   manufacturer_specific.xml  qees         vision
    act                       dragontech           ge          manufacturer_specific.xsd  qubino       vitrum
    etc....

Any help is appreciated, plan B is to buy a RPi and just use the All In One installer. I would really prefer to keep it in my VM environment both for backup/snapshot ability and to not have one more piece of hardware.

I started on a Windows machine but ended up going to the RPi and I never looked back. Everything is sooooo much easier. And with the AIO installer, you end up with a perfect install of HASS and OpenZwave Control Panel and it just works.

I don’t know enough about Deb on a VM container to help, but I’m sure someone here can help you.

But my honest opinion is that I think you’ll be a lot happier on a Pi.

Did you verify that you followed all the steps at https://home-assistant.io/components/zwave/ ?

Another potential issue is usb renaming. Help with that can be found at https://www.domoticz.com/wiki/PersistentUSBDevices. I use /dev/zwave as my persistent name.

From that path, it looks like you built PyOZW but missed the make install step. First, try specifying the full (not relative) config_path. If that doesn’t work, make install PyOZW then point config_path at the full path to the installed config folder. e.g. mine is /home/hass/home-assistant/lib/python3.5/site-packages/libopenzwave-0.3.1-py3.5-linux-x86_64.egg/config.

Thanks guys!

Thanks for the tip. I went back to check and I did make install, but I used the wrong path in my configuration. I updated it to (absolute)

/usr/local/lib/python3.4/dist-packages/libopenzwave-0.3.1-py3.4-linux-x86_64.egg/config

But the same error persists. I also confirmed that /dev/ttyACM0 has not changed.

Any other errors in the log around the ZWave error or that mention ZWave?

These are the only two things in the log, besides some session timeouts for my MQTT client.

Added a RPi3 to my Amazon cart :grin:
