Cant add OTBR integration, no url: works :Solved

Configuration Matter/Thread
1

So I whant to use thread , I installed Thread and Matter integration but cant install OTBR since I dont have the URL:
I tried http://ipadress:8081 and lts of versions but nothing is accapted?

if I go in under system/thread it says I have not a preferred network and none to choose from either.

So what url to use?

also It didnt “find” OTBR either I had to manually install it.

I used the conbee II stick using this guide.
https://smarthomescene.com/guides/how-to-convert-your-conbee-ii-stick-into-a-thread-border-router/
its on pie 4

You did change ‘ipadress’ to the address of your Home Assistant instance, correct?
Your HA instance is available on a flat network to whatever you are logging in from, correct?
You have IPV6 enabled on this network as well, right?

3

yes I used the ip of my HA installation, im on same network and vlan, no ip v6 isnt configured on my network at all , its just allowed in HA, HA use a random ip v6 adress when it whants to add an device it worked before but now I havent used its since mutiprotocol was removed, soo now when I got a spare stick i whant to use it.

iwe treid http://homeassistant:8081 ,http://homeassistant.local:8081, http://HA:8081 (as my router sees it)

Just to be clear, there are integrations and there are Apps (was AddOns). You need to install the OTBR App, configure it to use your ConbeeII, and run it. If it runs successfully, HA’s OTBR Integration should auto-discover it without prompting you for a URL.

I have the app with this setttings

device: >-
  /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2439268-if00
baudrate: "115200"
flow_control: true
otbr_log_level: notice
firewall: true
nat64: false

the device was copied from system/all hardware list

Aaaa it cant start the app!

6

Maybe turn the firewall off (for now at least).
Take a look at the OTBR App logs and make sure the OTBR App is still running.

it whont start

Under configuration in the app and under network in the bottom no ports is selected?
show disabled ports show the 8080/tcp and 8081/tcp as disabled?

The OTBR App is not happy with ConbeeII. I don’t use that device, so can’t really help on that part.

I updated the matter server and the latest HA core 2026.3.2 and now it works, dont know what fixed it but it runs now.
I also installed a new firmware the second newest from this location
https://phoscon.de/downloads/openthread/firmware/conbee2/

I tried to flash the latest again to see if it was fw that was falty but somehow it cant be flashed again, anyway it works now, tnx
