Z-Wave binding crashes under Windows 10

Hi there,

I know several topice here about crashing of zwave binding, but none of it had any solution that worked for me. Hope we can change this now.

I have openHAB2 running on a tiny PC with Windows 10 Home & JAVA 8. Everything works fine, even persistance, Grafana and connection to my self programmed MQTT-Client. But now I’m struggeling with the next step of installation, Z-Wave. I installed thebinding, and the stick is recognized by the system at COM3. But when starting openHAB, afer some time, when everything is to be initialized, openHAB crashes.

When I remove the Z-Wave stick, everything works fine agein (except zwave of course).

Many thanks,

Here is my openhab.log file (cleand up):

I don’t see anything false in my configuration, any hints out there?


  1. Please use code fences to make your post more readable This becomes especially important for configuration when spaces are importantwhere the forum otherwise “eats” spaces

  2. Exactly what version of openHAB? What Z-Wave stick? I have used my stick on a Windows 10 host bridged to a VirtualBox Linux VM running openHAB. In fact, that is how I first started evaluating openHAB.

Hi Bruce,

thanks for your reply. I have the 2.5.10 Release Build, and the UZB stick: https://z-wave.me/products/uzb/

Thank you.

Since Z-wave is region specific, in what country are you located?

I am in the United States. I am working currently so have limited time to look at this right now.

Sure, sorry, I’m in Germany :wink:

No worries. I have actually not tried running openHAB on Windows 10 directly.

Is this computer dedicated to openHAB or are you just evaluating the system?

Actually this should be my system of choice. I want to ave the power and flexibility of a PC, and I’m not a Linux guy.

Fair enough.
I am an old Linux guy but also work with Windows and have a son who is a Windows expert. In fact my main system is a Debian Linux VM running on my son’s Windows Hyper-V Server. My current personal laptop is Windows 10 Home so I should be able to test further is nobody else can help/

Really appreciate if you could help. I tried so much but it always crashes. Even on a new installation without any other binding…

OK so not necessarily Z-Wave related. I know many people run on Windows 10.

Here in the US this is a the Thanksgiving Holiday time of year so I am not sure of my time availability.

No sorry, wrong words. It always crashes when the Z-Wave stick is inserted - even on a new installation with no other bindings installed. It definitely relates to Z-Wave.

With no stick it runs smoothly.

Do you have the Windows drivers loaded for your stick? Have you tried contacting their vendor support?

This may not be an openHAB issue.

Yes, checked this. Drivers are up-to-date.

What do you mean by “crashes”? Does Windows still function after the “crash”, or do you need to restart the OS? Does OH still function after the “crash”? What is in the OH log right before the “crash”? Is there a stack trace? Are you unplugging the stick while OH is running? What other USB devices are installed in the system?

Having some more details will help a lot in troubleshooting. :slightly_smiling_face:

Please read also my 1st post. OH crashes, so it’s the Java application. Windows itself is still running, no problem.

Yes, there is a Java stack trace, I added extractions into my 1st post.

And of yourse I do not unplug the stick when OH is running. And no other sticks inserted.

Concerning the drivers, I downloaded the latest from the manufactruer’s site. It’s really the latest. You really want to the a screenshot?

Gerhard, which Java incarnation are you running on your box? The output of “java -version” in a cmd.exe-window would be interesting.

java version “1.8.0_271”
Java™ SE Runtime Environment (build 1.8.0_271-b09)
Java HotSpot™ 64-Bit Server VM (build 25.271-b09, mixed mode)

What is in the openhab.log at the time of the Java core dump?

I’m more interested in which drivers you have loaded than whether they are recent. A UZB device should be using the SiLabs drivers… something like CP210x. Which model UZB?

These are the last (zwave related) lines before the crash:

2020-11-23 08:22:42.341 [DEBUG] [ve.internal.protocol.ZWaveController] - Event listener added.

Well, I downloaded the latest drivers from the manufacturer’s homepage. Do you mean that different driver should be the better one?
