+Google Login support added with many thanks to: chrisjshull from <https://github.com/chrisjshull/homebridge-nest/>
+
+The values of `"issue_token"`, `"cookie"` and `"api_key"` are specific to your Google Account. To get them, follow these steps (only needs to be done once, as long as you stay logged into your Google Account).
+
+1. Open a Chrome browser tab in Incognito Mode (or clear your cache).
+2. Open Developer Tools (View/Developer/Developer Tools).
+3. Click on 'Network' tab. Make sure 'Preserve Log' is checked.
+4. In the 'Filter' box, enter `issueToken`
+5. Go to `home.nest.com`, and click 'Sign in with Google'. Log into your account.
+6. One network call (beginning with `iframerpc`) will appear in the Dev Tools window. Click on it.
+7. In the Headers tab, under General, copy the entire `Request URL` (beginning with `https://accounts.google.com`, ending with `nest.com`). This is your `"issue_token"` in `configuration.yaml`.
+8. In the 'Filter' box, enter `oauth2/iframe`
+9. Several network calls will appear in the Dev Tools window. Click on the last `iframe` call.
+10. In the Headers tab, under Request Headers, copy the entire `cookie` (beginning `OCAK=...` - **include the whole string which is several lines long and has many field/value pairs** - do not include the `cookie:` name). This is your `"cookie"` in `configuration.yaml`.
+11. In the 'Filter' box, enter `issue_jwt`
+12. Click on the last `issue_jwt` call.
+13. In the Headers tab, under Request Headers, copy the entire `x-goog-api-key` (do not include the `x-goog-api-key:` name). This is your `"api_key"` in `configuration.yaml`.
