@MikeClark, thanks for the help.
@Joemama1, thanks for posting. A few things: was this feature working before? If so, were there any recent changes made before the issue started? Did you try to fully reset your Lenovo smart clock and set it up as a new device?
Looking forward for your response.
Chiming in, please note that we have very limited support on third party speakers with built-in Google Assistant like Lenovo. It is best if you can reach out to them for better assistance.
For Google Nest display, there's a feature called Ambient EQ, a new visual experience that dynamically adjusts the color temperature and brightness of your display to create a non-intrusive smart display experience. When you use the sensor on the top of the device, Ambient EQ adapts the display brightness and color temperature to match the surrounding environment, so that your display resembles a physical photo.
