Hello,

Weekly I'm facing troubles with my Z-wave Stick, stick is dis- & connecting continuously.
I've tried to understand why it's happening, but couldn't find a good lead.
Are you familiar with this problem?

Suddenly it's stopping and everything is working fine without any problem.
Stick which I'm using is recommend type as described model(Aeotec Z-Stick) in the help file.

In my Win8 log file doesn't appear to be a problem with the stick or usb controller. I assume it's a software issue from bOS.

see attached print screen of log.

Any support is welcome.

Thank you in advance.

Hi Jure,

I've located the cause of the problem, if was the buffer setting of the Z-wave stick.
After decreasing the buffer, the problem didn't occur again. I've tested it with several settings and the settings as showed in the print screen below are working fine.


So you were right it was hardware related.
Thank for your support so far.

I'm having the exact same problem, but reducing the buffer only resolves it for a few seconds, could anything else be causing this?

Do you get the same "Port error received. Overflow" error? Have you tried increasing the size of the buffer?

I'll look into the issue first thing in the morning. In the meantime you can record the communication between bOS and dongle and send it to me just in case there's some other issue.

Hi Andrew,

I'm still facing problem sometimes. The Fibaro wall plug has a lot of parameters which can be adjusted. I had changed some of the report parameters(40,42,43,45,47), connection problem was getting worse afterwards, so I changed everything to the default settings and connection problem was much less, It still exist...once a week instead of every 2 seconds. It's still very frustrating, but it is working for a longer peroid.
A good solution would be really nice!
I'll wait for the feedback of Jure.

Dear Jure,

I've updated the firmware some weeks ago, but it didn't solved the problem. Last week I've ordered a new Z-wave stick and replaced the old stick, see photo of new stick.



bOS server is in operation for three days now and the error didn't appear. Looks like stick was main cause of problem. All other hardware hasn't been replaced or modified regarding parameter settings, etc.
I'll keep you updated if error problem is solved.

Best regards,

Dear Jure,
Finally I'm not receiving errors anymore. Problem has been solved with new stick.

Even the buffer settings can be adjusted to max positon, which improves the performance of whole Z-wave network, furthermore Z-wave Plus is much faster with importing new nodes in bOS.
