Nest wired doorbell pro

[Onucycle]

Do I need to be a Nest certified pro installer ton install these wired units?

It's not required if you are comfortable doing it, and are familiar with your electrical and doorbell systems.  I did mine years ago and it's been perfect ! Just follow the on screen instructions !

If you are able to replace a conventional doorbell, you should be able to install a Google Nest doorbell. You can find an install video on this Help topic:

If your doorbell's transformer does not meet the requirements found on the Help topic below you may need to install a new transformer:
