<!-- A clear and concise description of what the problem is or what use case you would like to see supported. e.g. I'm always frustrated when [...] -->

When someone repeatedly rings the doorbell it causes rings to “stack” on HomePod and when Siri recognizes a person she will announce “it looks like <first name, last name> is at the door”. This announcement will repeat fully over and over as many times as the button was pressed which can take a couple minutes and drive everyone crazy.

My 3 year old, however, finds great amusement in this.

**Describe the solution you'd like:**
<!-- A clear and concise description of what you want to happen. -->

A configuration setting allowing for X seconds of cooldown where a doorbell event isn’t sent.
Basically the same as the one that already exists for motion events.

**Describe alternatives you've considered:**
<!-- A clear and concise description of any alternative solutions or features you've considered. -->

Yelling “Siri, stop!” across the room (which didn’t work but that may have been because of the other chaos). Unplugging HomePod definitely works.
