So I have bought my Nest connect, works brilliantly.
I want to be able to see it in my Google Home App, however, when I tried to add it there, it told me to piss off and add it in the Nest App.
So I do that, go back to the Google Home app, go to link my nest account by going:
And then I get the following error:
Access Blocked: Nest's request is invalid
You can't sign in because Nest sent an invalid request. You can try again later, or contact the developer about this issue. Learn more about this error.
If you are a developer of Nest, see error details.
Error 400: redirect_url_mismatch
Not sure what I am doing, been trying for a week now, I have pushed the contact developer button and sent a screenshot. No reply from them at #
If I click the see error details, it tells me that the app doesn't comply with something called "OAuth 2.0"
We don't have a Nest Protect, but it has to be installed in the Google Nest app. You need to download and install the Google Nest app and open the Google Nest app then add your Nest Protect in that app; you CANNOT get to the Google Nest app by going through "Works with Google" in the Google Home app.
I'm just another Google Nest customer who is also frustrated with Google Nest's 2-app solution for its Google Nest products.
Sigh. Yes, its another idiocsycratic aspect to Google Nest's 2-app approach. You cannot see your Nest Protect(s) in the Google Home app: https://www.googlenestcommunity.com/t5/Apps-Account/Can-t-link-nest-to-google-home-app/m-p/188306
We have numerous older Google Nest cameras and doorbells. They do NOT use the "Works with Google" function in the Google Home app; the older cameras and doorbells can be VIEWED in the Google Home app (this happens automatically), but are still administered in the Google Nest app. I've never used the "Works with Google" function; I thought it was for non-Google Nest products that can work with Google.
All new devices must be set up using the Google Home App.
The strange one you can still buy new is the Nest Protect (from what I experienced) which only works on the Nest App and not the Google Home App.
In my current household, I am using:
All new Nest products released after Google bought Nest work with the Google Home App.
Again as @MplsCustomer noticed, the older line of products doesn't all work with the Google Home App but requires the Nest app.
It is NOT quite true that all new devices since Google bought Nest get installed in the Google Home app. It depends on the product. It's a mixed bag.
We have two Google Nest Hello Doorbells that were purchased long after Google acquired Nest; they are branded Google, but they got installed in the Google Nest app (but then appear with partial functionality in the Google Home app).
The Nest Thermostat E and Nest Learning Thermostat get installed in the Google Nest app (but then appear in the Google Home app).
And then the Nest Protects get installed in the Google Nest app and ONLY appear there.
