I can't install zWave on Home Assistant Windows installation in Virtual Environment

Configuration Z-Wave

Hi,

I’m trying to set up my Aeotec Gen5 stick for Home Assistant on Windows 10 Pro 64 bit / Python 3.7 32-bit Virtual Environment and I’m running to this issue:

It looks like it is looking for some kind of build environment. I’ve installed Windows 10 SDK but no success.

Any ideas how to move on?

Thanks,
Carlos

Additional info:

Earlier (not sure when, maybe before installing Windows SDK but I’m not sure) I got this when trying to manually install homeassistant-pyozw:

What type of VM Environment are you using?

I’m not an expert on Virtual Environments so I’m not sure which type you are using. I followed this guide https://www.youtube.com/watch?v=vnie-PJ87Eg to get it up and running in VirtualBox. I was able to get my Aeotec Gen5 stick working with it. Don’t remember if I had to do anything with the VM’s USB settings or not. I did however revert back to my Pi installation as the USB stick would keep getting disconnected at night

[16075.886832] usb 2-2: USB disconnect, device number 3

I followed a few other steps to disable USB Power Saving in Windows itself but that didn’t seem to work.

Hi @yakman! Thanks for your reply. I’m not using a virtual machine but a python virtual environment on Windows. Created with this command (as described here ):

py -m venv honeassistant

This is a “copy” of the original environment as far as I understand still running on Windows OS. Serms like the problem is that homeassistant-pyozw should be built while installing but it is not working on Windows dispite I installed dev SDK and Visual Studio.

Finally I installed python-openzwave as it seemed to be the same ad homeasssitant-pyozw and renamed the folders and edited metadata files in the package so the system thinks I installed homeassistant-pyozw. And it worked!

My problem finally was that the communication to the devices is very slow and unrelyable which is not something me and my wife can accept in ‘production’ (home).
Do you also experience such issues?

I did have some communication issues. Although my PC was located much further from my ZWave devices than my Pi was. So I thought the issues were related to the distance. My plan was to get a old PC or laptop and move the VM to that and place it closer to my ZWave devices, but I never got that far due to my issues with the USB Zwave stick getting disconnected.

Thanks for sharing your experiences!
I have also reverted to using a separate controller (ZipaBox) and communicating it by MQTT. This is still faster and relyable than the USB stick directly connected to the PC which is sad as originally I tried to switch to the stick to improve zwave performanve.

Could you post specifically what you changed to make HASS recognize python-openzwave? I made a quick stab at it yesterday but must have missed something.

Hi,

I zipped the folders so you can download them from here. You should unzip to Lib/site-packages. I hope this helps

Awesome thanks!

That part seemed to work, but when I try to se up the stick I get an error:

NM. I set it up through the config.yaml method and specified the path the config file. Seems to be working now!
