"Thank you so much for contacting eufy.
Unfortunately due to the function limitation from the Google side, The feature of ringing the Google device is not available to 3rd party doorbell while Amazon echo does. We are actively communicating with Google team and hope we can work together to make more advanced functions in the future.
Thank you again and have a great day!
Reference Ticket#62336916 if contacting a CSR"
