Some Google specific thread/matter questions

Hi at all,

I successfully installed a thread border router to home assistant, working with the dockerized matter server container. For testing purposes, I paired my nuki matter device with my border router (ESP32-S3/H2). I can control it without any problems by home assistant.

Now I tried to pair it with Google Home, I was successful by adding it, but the device always stay offline respectively reports to be offline.

Is there a network issue or would I need a second Google border router to control matter devices by Google Home, as it is stated there: Set up and manage Matter-enabled devices in the Google Home app - Google Nest Help?

Best wishes
