How is it possible?

Hi.
I’ve just installed a new, fresh, installation of Home Assistant 2022.10.4 (Operating System 9.2) on my Raspberry Pi4.
With my big surprise at start it recognize my Xiaomi Mi Temperature and Humidity Monitor that is a bluetooth device.
And this without install any ESP Home card that act as bluetooth gateway.
I’me very confused.
How is this possible?
Any idea ?
Thanks in advance.

Pi4 has built in bluetooth no need for esp gateway.

Ok.
I tought anything like this, but in the past I ever needed of an additional ESP Home card to do this.
Is possible is this related to new HA release?

Since 2022.8.x initially

Thanks again.
