@bulletprooffool I was in a similar situation like you, except I didn’t had a old web portal from nest. so here’s what i did to make this work:
- go to Google cloud console, create a new project, name it how you want.
- after creating the project, go to api and search for google sdm and enable it
- Create credentials for Oauth by configuring the consent screen and etc, please note: developer email and support email needs some email addresses, also redirect url should be https://www.google.com/ , there’s no need to fill in other domains or policy pages
- go to google device access portal and register for a subscription, it will charge you 5 usd
- create your project, copy your auth client id from the project you created in cloud console
and follow these steps: Authorize an Account | Device Access | Google for Developers
Please note: the authorization token is represented as access token in cfg file as @BHigg explained in above reply
Also, on Oh part, please make sure you don’t configure nothing via paper ui
all you need to do is to put the .cfg file in the proper path, fill in the fields and it should work. at least that’s how i made it work after at least 6 attempts.
Let us know if these worked for you
