Would be great to have a thread network map to help diagnose issues.
The OpenThread Border Router addon can show a network map.
You need to enable a port in the configuration. The default is 8080, then you can access the webinterface on http://<ha ip address>:8080/ and there is a Topology page.
Check the documentation of the addon for more info.
No, I deleted OTBR as it constantly caused issues. Tried it again recently with the same result so result so deleted it again. It is probably the Sky Connect. I have three google, one apple and one nanoleaf TBR’S on the same PAN on hannel 23. Found the network map in OTBR to also be inconsistent.
@Michel I have followed your instructions and enabled port 8080 in the OpenThread Border Router addon, restarted the addon, but when I navigate to http://192.168.0.30:8080/ in my Chrome browser, I get the message:
Is there something else I need to do, or change, or enable?
I think that is all I did back then. No clue what is wrong
Neither had I … 
But then I read the documentation again and noticed that it said “Make sure to expose both the Web UI port and REST API port (the latter needs to be on port 8081) on the host interface. To do so, click on “Show disabled ports” and enter a port (e.g. 8080) in the OpenThread Web UI and 8081 in the OpenThread REST API port field).”
Once I exposed the REST API port, I could connect to the Web Interface.
And I can now view the topology …

Hi all.
I’ve enabled the ports but when going there the site is just giving me a page on what matter and a border thread router is. There is no map or any info on the devices, nor any links to navigate away. The page wasn’t there before enabling the ports so that part works. I’m just not getting the info others are. What have I missed?
Are you saying that you don’t see this menu on the left-hand side of the web-page (http://192.168.0.30:8080/):
Where you just need to click on “Topology” to see the map?
The home page that I see doesn’t mention Matter at all, just Open Thread Border Router …
I just reloaded again and the menu is showing now. I swear it didn’t earlier as I even went trying to click on anything to get a menu.
Although, I think I needed to learn a lot more about thread/matter. My google hub max is not showing while it is listed in HA. Maybe they are too far apart. Also not sure why the child devices aren’t showing.
