Looking for Help - Aeotec Gen5 Doorbell

Started playing with home automation tech about a month ago and am now up to 29 devices… from arrival sensor, door and window open/close, lights and more.

Just have the Aeon Labs Doorbell delivered and installed. It is now running the Kevin LaFramboise code.

What I want the unit to do is when the back door open/close sensor is triggered the Doorbell triggers a particular mp3 file “02_Back_Door.mp3.”

First is there a way to do this?
Second, some basic guidance on how should get me started.

Thanks in advance for any and all help

Gotta love tech!
