Hey there!
I’m trying to connect a matter-via-thread device to my homeassistant docker container. I read many guides, for some reason my preferred setup seems to be missing something.
Scenario 1: Preferred
Homeassistant in a container, OTBR in another container with the ZDongle-E RCP connected and the matter-server addon in third container. Both are configured in the homeassistant instance, all looks fine.
Until I try to pair the matter-device. Then the homeassistant-mobile app complains that I need an OpenThread Border Router.
To verify general functionality of the components I tried different scenarios.
Scenario 2:
HAOS in VM, ZDongle-E RCP connected. Same output as my actual setup, looks good, fails to actually use the OTBR.
Scenario 3:
HAOS on a RPI4, ZDongle-E-RCP connected: This works. I can not figure out what’s different to 2.
Interesting:
If I run (2) and (3) in parallel and add the device in (2), it seems to be fine but underneath the OTBR from (3) is used and (2) stops working once (2) is no longer available.
I do not really want to migrate my homeassistant instance from the docker-container to a rpi (3), but guess I could settle to migrate it to a haos-vm (2).
Do you have any idea what’s stopping (1) and (2) from working? General tipps on how-to-debug-non-working-matter setups would also be appreciated! Thank you!
