I don’t know if it’s technically possible, because of the restrictions of apple, but it would be nice to be able to send tts-messages to siri devices.
Regarding to another post this is already possible with applte tv, when you set it up as a mediaplayer.
For alexa and ha it is already possible to ask alexa something. This triggers an automation and this triggers a tts to last called alexa device.
Would be nice to have the same for siri devices.
In a perfect case it should not make any difference which device I ask (iphone, homepod, mac, ipad), it should answer on the device you asked the question.
As I said I don’t know if this is even possible, as this would mean setting up those devices as mediaplayers in ha.
