Raspberry for multisensor + multiroom + presence detection: it is possible?

Hi all,

In few months I’ll move to my new home and as you may image my head is thinking on how to make it smart.

I would like to have a multiroom (wireless) audio system, a room detenction (based on BLE with xiaomi mi bands for example) and a multisensor (temperature, lux, motion).

So I know there are a lot of solution out there but I would like to “optimize” as much as I can so I was thinking on raspberry pi.

I’ve read many projects that use a Pi for every single task so my question is: it is possible to have all of them in a single pi?

The hardware exists: pir sensor, amp hat, enviro hat etc.

But what about the software?

I’ve searched for it but without luck. So maybe it’s impossible for some reason (CPU, GPIO conflicts)?

Thank you in advance!
