Network graph accuracy

[dwmw2]

Not sure if this is a bug, I'll start as a question... I don't believe the Network Graph is telling me the truth, or I just don't understand it.

Here's a sample:

There's weirdness in some of these routes but that might be true — for example the "Bathroom light" has "Connie light" as a neighbour, and that would be fewer hops. But I've seen nodes shown in grey as not accessible, even when I can ping them (and check back afterwards that they're still shown as inaccessible). Surely that can't be true?

But mostly... see that 'Primary controller' that's allegedly routing only to the ZWave-JS-UI 'Controller'? That's the real primary controller of this network., running on my production Domoticz box that I haven't yet converted to use ZWave-JS-UI. It works just fine when the USB stick that I'm using for testing ZWave-JS-UI is unplugged, so I'm fairly sure that it does have more routes of its own.

Am I misunderstanding? I know that operating as a secondary controller is not fully supported — is that what's making the routes get reported strangely?

There are different types of routes. You have ones that the controller uses to communicate with the nodes and then you have ones that the nodes use to communicate with the controller. I'm not 100% sure but I guess the map just shows the routes that the controller uses to communicate with the nodes. If you go to the statistics page of a device in the Z-Wave JS Integration you can see the last working route the controller used to communicate with a device.

Hm, where do I find that? If I view the list of devices in the Control Panel page, I see 'Statistics' if I click to expand a device, but that just shows me...

In home assistant go to Settings > Devices & Services > Click Z-Wave Logo > Click # Devices > Click on the device you want to view > Click : > Click Statistics > Click Last Work Route to see more details.

The network graph is built using the most accurated info we have from controller like:

LWR: Last working root
NLWR: Next last working route
Priority route: A custom route the user can set as the route the packets will take from controller to node
Priority return route: A custom route the user can set as the route the packets will take from node to controller

Everything is built by the internal zwave protocol algorithm and sometimes it's known to do some weird things, that's why we added the possibility to customize the routes

Ah, I'm only using ZWave-JS-UI, not Home Assistant. Once it's set up and running, I only really want it for the MQTT bridge (and the UI will just be taking memory on my router for nothing, as discussed in #3473).

[robertsLando]

You don't need home assistant to view that info, you can see that from ui too in network graph by clicking on a node

But only for some links?

But only for some links?

What do you mean? Generally the priority is only shown if you set it. The LWR details can be detected based on the color of the link, see legend
