the "doorbell action" is missing.

According to youtube videos, it should be at the very bottom of the list.

Hi, I recently bought a smart hub and button combo to do the smart doorbell. But I am also having the same issue as you. Here in the UK I am unable to see the option to build a smart doorbell. Perhaps it's a regional thing?

I have found a way to use the button as a doorbell and have the hub make a ringing noise. But there are no push notifications to my phone which is what I had wanted. 

Maybe there will be an update for Europe soon which allows this 

Would the TP-Link Customer Care staff possibly care to comment? Thank you.

You can simply achieve this need by navigating to the Smart tab in the Tapo App, clicking "+" icon to add a new automation rule.

Thank you for your hint. I created a new rule, and it mostly works (except the ring duration doesn't  reflect how long i pushed the button,  shortest ring time is 5 seconds).

Anyway, my problem is solved. Thanks again.
