Moving to a new Gen 4 Nest due to the support changes, are there any wiring changes for the base.

[TheMrPiazza]

I am taking advantage of the discount to upgrade my old nest (Gen 1 or 2) to the Gen 4. Can I remove it from the base on the wall and pop the new one on, or will I need to change the base of the unit as well?

I currently have (not sure if this is 1st or 2nd gen)

Model: Display 2.12

Blackplate Model: Backplate 2.21

You will need to use all three of a new mounting plate, new trim place and a new socket.

Note that you apparently need to have a "personal" as opposed to "Google workspace" account to use Google Home. None of the instructions online for using a workspace account provide any useful information and I was unable to enable my account for use with the Nest.
