The question was mostly a rhetorical one only remarking because everyone has BT enabled and I don’t have a device capable nor ESP32 etc sensors either. I remarked to bookmark for me to come back to but also probe this rather lengthy thread because I didn’t find anyone with such an experience reading above.
I suspect it’s because the underlying OS has bluez installed by default and HA is picking up it should register a Beacon listener though obviously it would be useless. I’ll find time and expand on this comment I’m leaving here further…
