Use Google Home Mini as doorbell chime

The following method (based on this post) announces a doorbell press on a Google Home Mini (currently branded Nest Mini).  The method will likely work with any Google Home/Nest speaker.

Required: Roku Video Doorbell [FrontDoor], Roku Smart Plug [FrontPlug], Roku Smart Home app, Google Home Mini [SpeakerName], Google Home app.

Assure that Roku Smart Home and Google Home accounts are linked (see this article).  Turn the plug off.

On the Roku Smart Home app, create two Device Triggers [FrontPlugOn, FrontPlugOff]:

1. FrontPlugOn — Trigger - FrontDoor Is pressed, Actions - FrontPlug Turn on
2. FrontPlugOff — Trigger - FrontPlug Has been on for 00:00:15, Actions - FrontPlug Turn off

Trigger 1 allows Google Home to be informed of a doorbell press by the state of the plug (on); trigger 2 resets the plug (off) for the next doorbell press.

On the Google Home app, create a Household Routine [FrontChime]:

Starters - FrontPlug Turns on

Actions -

1. Volume 0
2. Pause SpeakerName
3. Volume 10
4. Volume 8
5. Volume 10
6. Volume 8
7. Announce "Someone's at the front door."
8. Volume 0
9. Resume SpeakerName
10. Volume 6

Configuration - Play on SpeakerName

Action 7 is created using Communicate and announce; other actions are created using Try adding your own.  Actions 3-6 play a sound effect (see this post) when the speaker is paused, and action 10 resets the volume.
