Unresponsive z-wave unit

@MrBov

do I select the thing and use the Tools menu (top right) to select “Remove device from controller” to enter exclude mode on the z-stick? Then triple click the switch on the module?

Exactly.

@sihui thank you…

@MrBov

I can do that for nearby modules, but some of them are a bit further away, so doing it from the stick works better for me. Any risks or issues doing it that way?

Also note that unplugging/plugging a zstick (at least in Linux can cause the USB device to change (e.g. /dev/ttyACM0 to /dev/ttyACM1).

I tend to power down, unplug the stick to include/exclude, then plug it back into the same USB port and re-boot for that reason @mhilbush. Slow old process but seems to have worked for the last few years (I think )

So, I selected to remove node30 and the module flashed to say excluded as I would expect. Also OpenHAB told me the thing was not responding. I deleted the thing and did a factory reset on the module before re-adding it, now as node 78. Reconfigured the thing for the new node and all looks good…

But now I see that node 30 has re-appeared in the inbox. I guess the exclude did not succeed? How do I remove it now that the module has been reset and re-added as node 78?

I believe the process @chris recommends is to discover the Thing, mark it as Failed, Excklude the Thing, and then delete the Thing?
Not sure though. I have used Zensys Tools to delete from the controller.

Yes, this should (or could) work. Restart the binding before doing this - that will hopefully cause the binding to send the NOP command which seems to be what’s needed prior sending the “Remove failed node” command.

If it doesn’t work, then you’re probably stuck with the Zensys tool…

That’s what I use. Works every time.

[MrBov (Andrew Bovingdon)]

Marking as failed, excluding and deleting does not seem to remove the old node30, even after a reboot. Just following https://aeotec.freshdesk.com/support/solutions/articles/6000226205-z-wave-command-class-configuration-tool-download- to install the Zensys tool… see if I can work that one out

When using the Zensys tool, I follow the procedure described in this post.

Remove a ghost Z-Wave Node from HABmin

For those of you trying to remove a node using zensys tool here are the steps required: Highlight the node you believe has failed from the top left frame’s node list/table Toggle the “Quene Overrided” checkbox for this selected node (a check should appear) Send a NOP (i.e. no operation) command by selecting the exclamation mark from the tools menu Check to see if the node is failed by selecting the “is node failed” icon from the tools menu. If it has failed, you should see a message stating i…
