Hello Fleming755,
Good question! Please note that only the Google Nest Hub (2nd gen), Nest Hub Max, and Nest WiFi Pro (Wi-Fi 6E) can act as a thread border router with Google Home. We're always looking for ways to improve — we'll take this as feedback. You can also send feedback using your device by saying, "Hey Google, send feedback." Visit this link for more steps.
Let us know if you have additional questions or concerns about your Nest Mini, otherwise, I'll close the thread after 24 hours.
Cheers,
Muddi
