offtopic: My wife has fairly extreme ADD and loses stuff a lot. Tiles only work to locate something within a certain distance, and often seem to break.

I know it's a longshot, but has anyone here created a home positioning system for home that can use Bluetooth low energy beacons to locate objects to within a couple of centimetres in 3D space?

More ontopic: ESP32s are pretty amazing. Although I've not been able to keep mine stable and connected to wifi with MicroPython or CircuitPython, the range of stuff that's possible is astonishing. Mine is fairly old, I probably should get a newer one to see if it makes a difference.
