I spent decades in corporate America, generating presentations and graphs. One of the first things I learned about graphs is that you should ALWAYS provide a Label on the X and Y axis and enough information for the Reader to understand what is “good” and “bad”.
As for your Z-Wave Topology map. I would rate this a big Fail! I have seen it many times and still don’t understand what is says. Is Red good? What does Red mean? Is Blue good? What does Blue mean. Please take a few minutes to annotate this graph with enough information to understand what this graph is supposed to be telling me.
Please… I don’t want “you” to reply to this post with the explanation. I want the graph to be self explanatory.
Yup, that is what was written, I missed it. I wrote that graph off years ago since I it wasn't clear what it is saying, so I agree. At least a legend for Red and Blue. I figured it was time to ask AI about that graph. Your really need to already know what it does and how to read it, but maybe a link to a popup like the device graph legend could explain what it says.
Still, I can't imagine myself ever needing to look at this graph to figure things out, as the device graph seems to cover it. It is like this graph is provided just because it can be, not because anyone really needs to look it. Call me wrong if anyone has ever looked at this graph and then declared they that now see the problem with their mesh that nothing else was showing.
"Here is exactly how to read your specific map:
Red vs. Blue Squares
Blue Squares: The two intersecting nodes can see each other directly. They are close enough in physical proximity to communicate without needing a repeater.
Red Squares: The two intersecting nodes cannot see each other directly. They are too far apart or blocked by obstacles, meaning any communication between them must hop through a repeater.
White Diagonal Line: These represent self-intersections (e.g., where Node 0B meets Node 0B). They have no functional data value.
Checking Your Hub's Health (Node 01)
Node 01 at the top-left is always your Hubitat Hub.
Looking across the very top row (01) or down the leftmost column (01), you can see that nearly all your squares are blue.
This indicates an exceptionally healthy mesh foundation because almost every single device in your home has a direct, unrepeated line of sight to the hub."
No offense, but what you do and use is irrelevant to @dean's request. Which was for a legend to be included with the topology map. The topology map page isn't going to have a link to your post, so the explanation is not relevant to @dean's request. Further @dean specifically wrote:
I do believe you are trying to be helpful. But the need (or lack thereof) to use a topology map, or a description of what the colors mean, is not the help that @dean requested.
I suggested Hubitat simply supply a link with the explanation of what the graph means, so that is quite a reach to accuse me of suggesting that they link to my post, like you are just trying to find a reason to suggest I did something stupid. I clearly said that I have never looked up that info and I didn't know what that graph means, so I finally did that, and I simply posted what I got back.
I did not replay to @dean with that info, I replied to you that I missed this was about the topolopy map specifically, which led to the subject of the correct graph, so I don't know why you are accusing me of replying to @dean with info they didn't want, as clearly I didn't do that. It wasn't for @dean, and I didn't reply to @dean, so it was for anyone else reading this thread, who maybe like me, has maybe never actually looked into what that graph tells us. The topic of the post is that graph, so simply posting what it means and the actual info that is missing, is not off topic.
Yes, I think your reply is a bit offensive, accusatory, and picky. None of your reply was necessary or appropriate, especially for an Ambassador.
Edit: Note that the "view device graph" graph is a topology map by definition, they both are topology graphs, they just tell you different things. So I simply assumed the topology graph @dean was talking about was the topology graph, not the topology table. Not my fault how Hubitat labels those.
