A simple homeassistant AppDaemon app to send audio to a doorbird device.
In your AppDaemon configuration, include ffmpeg in the System packages and python-ffmpeg in the Python packages.
Place the following in your apps.yaml:
doorbird_audio:
module: doorbird_audio
class: DoorbirdAudio
Add doorbird_audio.py to your AppDaemon apps directory.
Create a home assistant script to raise the "doorbird_audio" event with the device's ip, username, password and a url to the audio of your choice
You can raise this event from wherever you like, for example from a trigger or button.
