Z wave device errors

[chris_birkinshaw]

Hi there,

I am using housebot with the TrickleStar USB zwave dongle. I am able to reliably turn on and off lights using homeseer ZTool, but housebot is not proving to be very reliable.

Following a restart of the housebot app I can usually trigger a few scenes successfully, however after that zwave functionality stops working. Strangely, just before failure scenes are sometimes executed correctly but housebot says they were not.

I have noticed this in my logs repeated many times:

Z Wave Error WaitCommEvent() Error = 5
Z Wave Error WriteFile()

Do you have any ideas?

Thanks,

Chris

EDIT: Also I am unable to view associations (this times out) but I can set them - which seems odd

The waitcommevent error looks like the USB gets disconnected.
Are you sure there is no OS (driver) problem or anything else at that time?

That message looks suspiciously similar to one I was getting when I was using a 2 serial port USB/RS232 dongle. I replaced it with genuine RS232 COM ports - a 4 port serial card. No problems yet. Can you try talking to Zwave via standard RS232 serial in some way? Or as Lostdreamer suggests, maybe update the drivers for the USB dongle you're using. What I found with my problem was that it SEEMED to occur after a Windows auto-update and rebooting the server PC "re-established" the ports associated with the USB dongle.

This was using VMWare so I think you could be right! Getting one of those Silex USB 2.0 over gigabit ethernet device servers and will see if that helps.

Many thanks for the tips,

Chris
