Is it possible to customize the message sent using the new Alert component

I haven’t had a chance to test the alert component, but will it be possible to customize the message that is sent in the alert? I don’t see in the documentation how that is done.

Whatever you name the alert, that is the message that is sent. In the example:

# Example configuration.yaml entry
alert:
  garage_door:
    name: Garage is open
    entity_id: input_boolean.garage_door
    state: 'on'
    repeat: 30
    can_acknowledge: True
    skip_first: True
    notifiers:
      - ryans_phone
      - kristens_phone

The message would be “Garage is open”. You can also use states and variables like you can in notifications.

Ok. That makes sense. What about including images and things like that?

Don’t know if that is supported. I don’t think so.

How can I trigger e.x a sonos notification script, by leveraging the notifiers part of this component?
Is it even possible?
I mean, this component seems to be ok for mobile messages, but I think it would be just as suitable for TTS notifications.

I’d like to use actionable iOS notifications, like:

“The coffee machine has been on for a long time…”
<Turn it off>

It looks like the alert component isn’t setup for this. Is that right? Would I have to recreate a “normal” automation to do this?
Is this sort of feature planned for alert, or will it always be simple?
