If you have an Alexa-enabled device, the Nest Hello doorbell will not ring or notify you of visitors. The Nest Hello doorbell's live feed can be viewed by connecting it to an Amazon Echo Show.
Enable Google Nest on your Amazon Echo Show to get started. Allow Alexa access to your doorbell camera's live stream by turning on access to your home's information.
Log in with the Gmail account that you used to set up your Nest Hello doorbell. Make sure to tap 'allow' when Alexa asks for your trust. It appears that your Alexa device has successfully connected to your Nest Hello door bell.
