HomePod Which device will Hey Siri activate on

[Fatboy71]

I expect this question will have already been asked:

I am thinking of getting a HomePod.

I have Hey Siri enabled on my Apple Watch, iPhone. If I enable Hey Siri on the HomePod, which device will Siri activate on, when I say the Hey Siri command, or will it activate on all the devices I've mentioned?

HomePod (when it’s working as designed)

Seems to work a lot better since the last software update

It's not perfect but usually the HomePod. As another mentioned it is better than it was at launch.

when I say "hey Siri" I see my iPhone and iPad light up, but they quickly turn off once the HomePod takes the command. (under 1 second)

if my phone screen is on when I say "hey Siri" (doesn't seem to matter if it's locked or not) the phone will take the command.
same for the watch, wrist raised & screen on, "hey Siri" will trigger the watch.

if the watch and phone screen are both on. it triggers the watch (phone never acknowledges it heard anything)
