Use Multiple Echo Dot's as Alarmo Siren

[jparker80]

I'll start by saying I'm brand new to Home Assistant (been using it about a week) and pretty new to yaml in general so I apologize if I'm missing something obvious.

Issue: Added 2nd Echo Dot to act as additional "siren" for my Alarmo setup and cannot get it to repeat the audio clip on both at same time, but works fine when set to 1 Dot (hope that makes sense?)

Here's the yaml, when set to only deliver the script to the "Living Room Dot" it works and the sound repeats multiple times, once I add the Bedroom Dot into the mix, they both only play the sound once.

Basic operation is when Alarmo is triggered it turns the volume to 100% on the dot(s) and then plays a 5 second audio clip 5 times and then turns the dot(s) volume back to 40%

Any ideas on how to get this to work on both dots? Thank you in advance!
