Combining border routers to one thread network

Hi,
I have a ZBT-2 setup as ha open thread border router. i also have a Ikea dirigera hub and a tado bridge X. i want to combine these in to one network for better coverage.

starting with the Ikea dirigera i cant seem to make it switch thread networks from the tado one to the prefered home assistant network.
in the ikea app it seems to want a 9-digit code as network credentials but i cant find anything that looks like that in home assistant. i cant seem to move it in HA under the thread integration.

The Tado bridge X doesn’t let me do anything in the app related to thread and i cant seem to move it in HA either.

please let me know how to at least move the ikea one.
Thanks.


That’s on the box you threw away after you installed it, most likely.
Possibly on the device itself somewhere. It’s unique to each matter hardware device.
