There is zniffer software used by some here to do that. I have a he stick but have not really used it.
Is this possible with OH3 tools or do I need Silabs for it?
You need the Silabs software or some other means of resetting the controller. It cannot be done from openHAB.
This problem has reappeared. I upgraded to the latest OpenHAB (3.4.4).
I had 2 dead Z-Wave switches and replaced them with Zigbee switches.
At first all went well but less than 24h the whole ZWave network is back into a slower than a snail…
I really do not want to reset everything again and start over. Does anyone have a better idea?
For those not wanting to read the whole thread again:
you have zombie nodes in the network
the network is getting swamped by something
if you have the means to sniff traffic and figure out what is doing it might help
how many nodes in the network (I’m not going to read the whole thread, sorry)
Do you have nodes that have a ridiculously high reporting rate set?
Have the two dead switches been excluded or whatever (removed from system)
Do you run nightly heal?
The two switches were repeaters and any battery nodes that used them in the mesh may be stranded
I guess try to add more detail about the network in general
There are about 40 active nodes on the network. Nightly heals are run, yes. They have not helped.
There are no nodes with ridiculously high reporting settings.
The two removed nodes could not be excluded. They were dead from the network before I pulled them from power. They do appear in the Z-Wave network map with dashed unidirectional lines.
I tried to get OpenHab remove the nodes from the controller to no avail.
I can run any test you’d suggest.
I did a comprehensive writeup about removing nodes here. In my cases slow networks were always related to these.
I tried to remove the zombie nodes as instructed in the pdf. Unfortunately, I get an error:
Remove Failed Node failed in 00:00:04.011
What did it say after the “check” if failed?
Your writeup says Use the zensys z-wave pc controller tool to delete nodes
However I cannot find that tool.
Can you give me a link on where to find that?
(Several links are dead)
Tried again. The Is Failed
operation results in Is Failed Node Check failed in 00:00:04.072
I believe it’s now part of Simplicity Studio 5.
Interesting? Usually that means the node responded, so can’t be removed. Only failed nodes can be removed by that method. Did you see any message from the node? Click on the letter icon in the upper right (second one in)
@apella12
That’s actually empty.
Note that, whenever I restart the ZWave PC Controller, remove the stick, re-insert it, the stick lights flash regularly. As soon as I ask to mark the node as failed, the lights do not flash anymore. The light will change only after very long wait times.
Also those node cannot be replying, since they are now disconnected from the power.
PS: If having about 40 to 50 devices creates this kind of situation with ZWave, it seems to me the whole protocol was not well thought out. I have started replacing ZWave devices with Zigbee. I am never going to add another ZWave device or recommend ZWave to anyone…
However replacing all my devices is an expensive enterprise…
I have two Aetec 5+ sticks. Is there a way to transfer the config from the one currently paired with all the devices to the other one? Can it be done via a configuration file where the dead devices could be manually removed?
All that probably means the check if failed message never got through.
I have had 40 to 50 zwave node networks running for some time without a problem, but that doesn’t help you.
The are a couple of options for the other stick (assuming it is blank).
Actually, one thing in my previous post is incorrect. The sticks are Gen5 but not Gen5+
Can I put a backup from Gen5 onto a Gen5+ ? (using ZWave cloner downloaded from domotic-hobby.com)
Could it be that the latter’s firmware fixes some issues?
Unlikely.
The quick way to tell is to try the PC controller backup, if there are errors then the answer is no. There is an older Zwave backup utility that can work on older sticks. Adding the stick to the network should work regardless of version
