[2.2.7.125] Z-Wave Ghost Nodes

I have a stubborn ghost node (device physically dead and pulled) that I can't seem to Remove.

Below is the log output from a Repair attempt, multiple Refresh cycles (have done this process a few times), and failure to ultimately Remove the node.

Node only ever says Pending even after identified as unreachable.

If it is a mains powered device and it is online like this one is, it should discover..

Do me a favor @rhinoroo.. Reboot and only click refresh if it does not have the remove button.. Repair is not your friend on dead nodes ..

You only want refresh and remove on ghost nodes..

Thank you @bcopeland that is good information to know on the Repair side.

Completed the reboot and did a Refresh (twice) and then attempted Remove.. still no joy.

Node still shows Pending with log output as below and same image as previously shown.

Nope, never does. BTW, this is on a C-7, 2.2.7.125

Summary

It did discover the device... and found there was no matching driver, so it picked the closest guess a driver named "Device". :smiley:

Aeon Labs device perhaps: Aeon Home Energy Meter (ZW095-A) ??

Ahh but it did.. It didn't find a matching fingerprint.. so it matched it to "Device"

Yup.. just matched up the manufacturer / deviceType / deviceId:
https://products.z-wavealliance.org/products/1289?selectedFrequencyId=2

Thanks, but this opens up another can of worms then. I do have that device but I have NEVER tried to pair it with this C7. I use to have it paired to my C3 but didn't have any need to connect it to the new C-7.

So why would it grab it? What if this would have been my neighbors device? Not good that it would randomly grab a device I didn't try to pair.

But problem solved on the node. I can now delete it. Thanks.

It would have to have been not in a network and sent a NIF (Node Information Frame) while you were in inclusion mode.

@bcopeland Just FYI this is what I was always getting as well when trying to remove ghosts on my C7 (network busy). Then it would basically bring the whole network to a halt if I kept trying and I would have to reboot. Once I got a USB stick I went in with that and two clicks and they were gone. Come to think of it the whole thing has been much more stable since I got rid of them.

Typically, I would do the same @jtp10181 and I’ve never had any problems removing them with a stick as you noted.

Let me know if you’d like me to proceed with additional troubleshooting @bcopeland otherwise I can take my usual path here..

You can go ahead.. I have the information I need now.. Thanks

Is there a guide to the status values?

I got: Failed node 49 remove status: 1

Update: after reloading z-wave details it appears the device is gone now.

I had tried removing this device a day or two ago and I got the dreaded "Z-Wave Network responded with Busy" message. So surprised it worked this time. :slight_smile:

My current ghost device issue was caused when removing a particular Zooz device. I have since reset this device. Is there any concern with me adding this specific device back into the network while there is still a ghost device for the same physical device? Or should I first wait until I am able to get rid of this ghost device?

I have ordered a UZB Stick and will receive it tomorrow. Would you prefer I wait a while to use the Stick to delete the ghost device? Or is it likely that troubleshooting and resolving this problem is going to take a while?

Sooo, bcopeland, what are you thinking???

I'm having issues removing a ghost node also. I'm seeing this in the logs after hitting remove:

sys:12021-05-16 17:47:56.893 Failed node 0F remove status: no reply
sys:12021-05-16 17:47:46.914 Z-Wave Network responded with Busy message.
sys:12021-05-16 17:47:16.868 Z-Wave Network responded with Busy message.

And sometimes:

sys:12021-05-16 17:48:36.411 Failed node 0F remove status: 2

The device has been reset manually. Will I need to remove power from the device? It's currently still wired into the light switch and I hope to be able to re-include it eventually.

This is likely the device responded and as such is still active in the mesh..

Thank you upfront for any help. @bcopeland

C7 running 2.2.7.126

click "remove". takes about 15 seconds, page refreshes, still shows this:
