Unable to remove "unknown" Zwave node

[Bikey]

Since my upgrade from 4.7 to Domoticz 2020.x (now on 2020.2.12067) I have an unknown Z-wave device that is being "found" and can not be removed.

After each reboot I get this message:
2020-05-20 11:52:12.173 Status: OpenZWave: New Node added. HomeID: 3284788832, NodeID: 35 (0x23)

Since I never included this sensor I can not remove it via the Z-Wave Control panel as this waits for an exclude message.

So the only way for me to remove it is to use the Delete button in the Domoticz Z-Wave node-overview. I then get a pop-up saying that this may take a while, but it is removed from the interface Immediately.

However if I look in the log I see:

2020-05-20 12:32:08.309 Status: OpenZWave: Remove Failed Device initiated...
2020-05-20 12:32:08.310 Status: OpenZWave: RemoveFailedNode ControllerCommand - Starting
2020-05-20 12:32:08.403 Status: OpenZWave: RemoveFailedNode ControllerCommand - Failed
2020-05-20 12:32:38.001 Status: ZWave: Stopping Controller command (Timeout!)

I have a similar situation with a device that I can not manage to exclude, but want to remove anyway.

Is this a bug? What can I do to resolve this?

I have the same issue, however I have had no time yet to try to resolve it. I while ago I found this topic, and when I have some time I wil read and try.

I you try it please report back...

Hello, I have the same problem. In that topic they edit the zwcfg_xxxx.xml (sudo nano /home/pi/domoticz/Config/zwcfg_xxxx.xml)
But I don't have that file. I'm running Domoticz with a z-wave controller for several years.

When the raspberry pi crashes of the power is turned of the right way, I get this problem.I also need a solution to remove that devices.

Does anyone does know how ?

Greetings,

I can report that after 2 attempts this worked for me. The issue however is, that - besides that it is quite cumbersome to edit XML-files - this only works for nodes that are actually present in OZW cache-file.

I also had a "ghost" node that was not present in the cache-file. For that I finaly succeeded removing it after multiple actions in the OCWCP, as I described here.

I guess the zwcfg_xxxx.xml is introduced in Domoticz 2020.x if you are using an older version that might explain why you dont' have thise file.

You could try to use the OZWCP to remove the node, by repeatedly doing the same as I described in this topic.

My idea about this was to have OZW try to query the node so much, that at a point in time it should find out that this node is not reachable: e.g. "dead". After that the node can be removed successfully.

For some reason, OZW does not allow you to remove nodes from a network if it stil thinks that it is active.

Hello,

Thanks for your answer. I use version 2020.2 so that can't be the problem. What you say is the problem I think. Dead nodes can be removed with the OZWCP. OZW thinks they are still alive, so can't be removed.

Hi guys,

I've been really struggling with this issue for quite some time.. and trust me, I have tried everything in this forum without any luck.. Until I stumbled across some other forums that fixed the problem for me.

Short version: As far as it looks Domoticz and specifically the control panel (ozwcp) lack one critical function:
"Mark battery device as failed".

Turns out that battery powered devices needs to manually be set to failed in order for the controller to mark them as "dead". Then you can remove them without any problem!

Please correct me if I'm wrong here, but this was the only way I could solve my issues.. Had multiple devices that the controller just couldn't remove.

My solution:
(note, I'm on a RaspberryPi with a Razberry controller. I do not know if this works for other controller.. but I do believe so..)

0: Backup you current installation!

1: Stop Domoticz.

2: Download and install Z-Wave Me.
https://z-wave.me/z-way/download-z-way/

3: Connect to the web interface at http://localhost:8083, enter expert mode and select the controller.

4: Select your device and "Mark battery device as failed" (see screen shot).

5: You can now either "Remove Failed Node" direct in the same GUI, or shut it down and return to Domoticz that now will actually accept that the node is in fact dead =)

6: Done!

I hope it might help someone. Personally I would love to see "Mark battery device as failed" in Domoticz!!

Thank you very much for this htilly!!
This helped me also, as you I have searched and tried everything without success. Until your brilliant post here. Would also like to have these features built-in the OZWCP. But at least now with this tool I can relatively easily just stop domoticz, start the services for the z-wave.me tool and actually get some z-wave work done.
Great, thank you very much for sharing this!
