Nest Doorbell 2nd Gen wired how to set up? No serial or QR code

[Perry1000]

I purchased this camera in the summer of 2021 at the beginning of an ambitious home remodel. We put off installing it until the new porch was completed, and now it's the finishing touch. The doorbell was opened but never used, but it was in a shed half out of the box and the QR code & serial are illegible and wiped away 😥. I have the box with original serial number and item number. The doorbell lights up and chimes yet I can't get it to install without that 6 digit code. How do I obtain this? Plugging it into my PC does not register anything.

Is the 6-character alphanumeric setup code also wiped away? If it is legible, you should be able to select "Continue without scanning" during the install to use that code.

If you have the 2nd gen doorbell and you saved the Quick Start Guide, the QR code is supposed to be printed on that.

You need either the QR code or the setup code to install the doorbell.

I was able to get the 6 digit code off by an acct of God and manipulating it under different light sources. There was a slight indentation left on the surface from the ink..

Terrific!  Write it down and save it!  We've been doing that for years, to make sure we can reinstall later.
