Hello, I'm trying to find a way since a while to display automatically the doorbell video stream when someone rings the bell.

I know this is possible with the tapo app but user must accept the call to see the stream..

I've heard that it is implemented in Alexa Echo show but I don't have this device.

I only own a Samsung tablet. 

Smarthings can only notify a doorbell pressed but does not provide a way to automatically switch on live stream.

I've tried solution with Home assistant, but the doorbell press event is not exposed so I cannot make automation.

If someone has an ideait would be really appreciated.
