Bluetooth presence without smart speakers?

Is there a good way to have presence with low power bluetooth tags or similar using a USB dongle or similar?

I don’t want to put smart speakers or similar listening devices all over, but I would like to have something that can pick up faster than WiFi when someone comes home in their car and tell if trash cans are at the house or curb.

I have no idea what this has to do with smart speakers!

I see a lot of the guides talk about using Google Home smart-stuff for bluetooth presence tracking. I don’t want that stuff.
