Yesterday was a first in our household: all three of my linked FireAlerts started beeping. (luckily, there was no apparent reason for that...)
Since these are from before the HA era, they are not integrated.
I do have an Apple HomePod, and that has a function to listen to these types of sounds. And yes, that threw a notification on my iPhone via the Home app.
It dit make me wonder though if/how we could integrate this into HA. There is the Homekit Device integration, but that does not see any HomePod entities/alerts. Nor do the Apple TV integrations. Homekit Bridge goes the other way, so I see no obvious way to bring any of the functionality the HomePod offers into HA?
Would be of great value though, so hope anyone else has some ideas.
