There is a lot of complexity lurking there. At a second home I have HA running on an RPi and also an Apple Homepod Mini (with Matter). I wish someone could explain to me how these two devices do (or do not) interact, and how I can get Apple Home on my iPhone to play nicely with HA both locally and (when I'm away) over Tailscale (so I can do remote operation of thermostats and a heat pump on wi-fi).

Is this the kind of scenario that I should be asking an LLM to sort out for me ?
