Yeah I have done that too. I do not get many, just happened to be zniffing when I saw the post. Of my 46 nodes, 36 are direct shots, 4 need a hop and 6 are 2 hops. For me, never really see CRC on the close-in nodes and it is always with low RSSI.
Maybe surprisingly

Bob,
Yes, Chris Cheng is a real person who besides Sebastian doing the the support - I asked him he confirmed that 
Probably one of the best support I ever got.
I tried to download the Software as described in your linked page (I registered first)
but I always get the following message first:
“Please download either a Controller SDK or Embedded SDK before downloading Z-Wave tools. Contact support if any queries.”
How did you get around this? (or do I have to download Simplicity Studio?)
cheers
Stefan
One of my problems is that I don’t take great notes. I vaguely remember something like that and poked around the site and may have downloaded a SDK, but I did not pay anything, that’s for sure. Also I had Simplicity studio installed some time ago. It has the Zniffer app, but you need the programmer and it does not have that. Since I have both a standalone Zniffer and one in the Studio, I must have gotten the download to work, let me see if I can recreate/recall/find what I did.
Bob
edit: So I think I downloaded the SDK here. I downloaded another copy and it looks like what I have.
Were you able to use the Aeon Backup Software to backup yould old Non-Aeotec stick?
Yes, that was what surprised so much. It worked like a charm.
That is indes surprising…which Stick did you have?
Thanks Bob, I found out that the issue is actually that the tabs, hence the download tab, doesn’t work in firefox. So one has to use a different browser. I added the Silicon links to the top of the thread.
Btw, I definitely recommend to read the “Z-Wave networking Basics” pdf that comes along with the SDK download.
Even though the installation process is described in full detail and nothing is missing, here are some tips to become succesful in doing it as the process is far from being intuitive.
Finally the nerd factor is pretty high when it works 
Good Post. Should be helpful to others !
Bob
Thanks for posting this.
I’m struggling with how to recover nodes 2-5 on this stick. Is there any way except by resetting the stick?
Using PC Controller you can remove the zombie nodes. I think it is up to the controller whether to re-use the IDs though. Removing the nodes is recommended to maintain network health.
Short answer is no without a factory reset. I have read that once the maximum number is reached ( and it’s somewhere in the 230-255 range, new Nodes will be assigned in the unused spaces (like 2-5) in your case, but I can’t verify that. I have 47 nodes and my last one is 79, for example.
Bob
You are correct.
232 is max and then any unused id are assigned starting with the lowest id.
.
As you only have one node do a hard reset which will remove all nodes and start a new network. The home id will change and the next node you add will be 2. Remove node 6 first so it is ready to add to the new network.
Add your nodes working out from the controller by distance so low id are nearest the controller. Z-wave routing works best in networks built this way.
Thanks @Andrew_Rowe for pointing me at this @stefan.hoehn post.
After weeks of digging I think I have located 3 problem z-wave nodes (at least)… 2 are Fibaro sensors, outside in waterproof boxes, both have had water get in and are totally dead. the third is a Fibaro dimmer which I thought I had removed ages ago but is still showing up on the z-stick. The module is definitely not connected any more.
I have downloaded the latest zensys z-wave pc controller tool and plugged my Aeotec z-stick into the PC. I could not find any “Queue Override” checkbox to toggle? I assume that was an older version?
I highlighted the first of the 3 nodes (the Fibaro dimmer) - I clicked the “is Failed” and it did a NOP and an Is Failed Node Check - telling me that the node status “is failed”. I clicked “Remove Failed” and it returned to say that “Remove Failed Node completed”. The Node seems to have gone from the list… All good I think 
But the 2 Fibaro sensor modules are a problem. Both are totally dead, so I can’t press the buttons to remove them etc. NOP fails to each as does Is Failed.
What to try/test next? Anyone have any ideas?
Over time helping people who report sluggish performance from a zwave system, it always turns out to be zombie nodes on the system… always… every time. Often, one offline node is enough to cause huge problems. I think you are on to the issue, can’t advice how to proceed as I haven’t used the pc controller tool but good job figuring it out so far and keep digging
Report back if you figure out how to remove the other two dead nodes and maybe somebody with experience using the software can jump in to help 
So I literally tried everything… from both OH3 and from the zensys tools… Both removal and replacement routes… No idea what I changed or did, but suddenly the node responded positively and eventually got deleted… So I now seem to have a z-wave network with no new errors…
My concern now is the distance between the house and the garage nodes… especially with wet bushes… May need to try the 2 z-stick approach next… Still so many things to do… but I’m hoping it starts behaving reliably again now… fingers crossed
Thanks for the help.
That is good news indeed!
Well, I’m sure you realize that mains powered nodes can act as repeaters and extend the mesh network’s range so maybe you have already strategically placed mains powered device between the two structures and it is just to much distance but if not give that some thought
me as well, but report back on that in a week or two
