I'm going to buy a new house and I would like to add a multiroom solution using raspberry pi + hi-fi berry amp and on wall speakers.
I would love also to add a pir sensor to the pi in order to allow, via my home Assistant server, to push music only to the room where there's someone.
I've noticed that all the pir sensor use the gpio already occupied by the HiFi berry hat.
Do you know some other solution that can be used to reach the same result?
I saw that I can use a pi cam with opencv to monitor movement, but i don't want a cam in every room (bathroom for example).
Thank you in advance.
