Then you either already migrated from a Nest Account to a Google Account at some point in the past, or you started using the Google Nest app after Aug. 19, 2019:
Why do you think you need to do something?
Thanks for the help, @MplsCustomer
@Hendog, thanks for posting. Which Nest camera are you trying to set up? If your account is already migrated to Google you can use that account to log in to your Google Home app and your other Nest devices should show in it. Now you can use that account to set up your new Nest devices and control everything in the Google Home app.
Let me know how it goes.
So, I can see my old cam and my new cams under the Google Home app, but they are under different residences. Under the Google Home app, I don't get the 60 day history on my old cams. I'm guessing, I can remove the new cams and add them under the original residence in Google Home, but what about the history?
A Nest Aware subscription (such as the Nest Aware Plus subscription, which provides 60 days of event video history and 10 days of 24/7 video history) applies to just one Google Nest "home/structure".
You are supposed to be able to move cameras from one Google Nest "home/structure" in the Google Home app or Google Nest app to another Google Nest "home/structure", though we've never had to do so:
It's hard to tell what's really going on in your situation, based on what's posted here. Let me try.
First, Google Nest decided that the new Google Nest cameras and doorbells released starting in Sept. 2021 would work ONLY in the Google Home app and NOT in the Google Nest app or on the home.nest.com website.
Second, live feed for older Google Nest cameras and doorbells can be viewed in the Google Home app and on the new beta/preview website, home.google.com (along with the newer cameras), but history for the older cameras and doorbells can still only be viewed in the Google Nest app.
Third, a Nest Aware subscription (such as the Nest Aware Plus subscription, which provides 60 days of event video history and 10 days of 24/7 video history) applies to just one Google Nest "home/structure", but it applies to both old and new cameras and doorbells, with history for the old ones viewed in the Google Nest app and history for the new ones viewed in the Google Home app.
Fourth, it seems that you have managed to set up two different Google Nest "homes", since you referred to "different residences". If that's the case, then you're going to need to figure out which of the two has the Nest Aware subscription.
In the Google Home app, select each of your Google Nest "homes" one at a time and go to Settings | Nest Aware and see which one has the Nest Aware subscription. You'll also need to figure out whether some of your cameras are in each of those "homes". If some of your cameras are in a "home" that does NOT have a Nest Aware subscription, then eventually you will need to move your cameras to the Google Nest "home" that has the Nest Aware subscription, since Google Nest has no process for moving a Nest Aware subscription to another "home".
Fifth, the reason you can't see history for your older camera(s) in the Google Home app is because their history is only available in the Google Nest app.
Lastly, I understand you don't want to use two apps to track your Google Nest devices. Unfortunately, Google Nest does NOT give us that option. We've had to use the Google Nest app AND the Google Home app since Sept. 2021 when we bought one of the new Google Nest battery cameras and discovered that it works ONLY in the Google Home app, while our older cameras still work in the Google Nest app. We're still waiting for them to make everything work in the same app.
You've been amazing providing that detailed information, MplsCustomer we really appreciate it.
