Deleted house in Google home no qr code

[MarcR]

By mistake, I deleted Google house from my Google home.
As a result, I cannot use my Google nest mini to its full potential.
I want to put it in a new Google home but this only works if I reinstall the Google nest mini. The problem is I have no qr code and no other information of it my 3 Google nest mini 2nd generation. Is there any other solution?

The Nest Mini doesn't use a QR code during setup.

However, you will need to do a factory reset first:

Here are Google Nest's install instructions; you mostly follow the in-app instructions:
