Entry pain. Scroll up to set mode and scroll down to set the temperature
Open Authentication is a pain since Google Blocks OAuth Requests Made Via Embedded Browsers. If you try to complete OAuth on the device you are confronted with the first of these two screen shots. This is as expected. Sadly you cannot complete the authentication now as Google refuses based on security of using an embedded browser.
This means you need to complete authentication in a supported browser and copy the OAuth code across to the application. Not the best user experience!
Nor is it possible to use limited input devices for authentication (see OAuth 2.0 for TV and Limited-Input Device Applications) because SDM is classed as a high security scope.
