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.

- sintezcs 3y agoI have ESP32 devkit board running micropython that is connected to Wi-Fi and MQTT and publishes sensor readings 24/7 for weeks without any issues
- bloopernova 3y agoWhat type of ESP32 is it? S3?

- nirav72 3y agoThanks for this. I had no idea a ESP32 board with built-in PoE existed. I've been using a PoE to micro-USB adapter to power a ESP board. While it works, the adapter just doesn't look very clean when mounted on wall.
- matt_trentini 3y agoThere are a few; the wESP32 [1] is the nicest I've used but the Olimex ESP32-POE [2] is widely used too. The maker of the wESP32 also recently released a neat RP2040 based PoE solution you may be interested in: the RP2040-Shim [3] to match the already-existing PoE-FeatherWing [4]. Together, they're a small, neat solution. (Not involved with those products, just found them well-designed/interesting.)

- DrFlipper 3y ago>MicroPython or CircuitPython Well, what do you expect? These are verboten for any kind of reliable embedded system.
- Reviving1514 3y agoOn the contrary Micropython is even used in medical devices. I've used it extensively and it is great. With ESP32 peripherals you can even get extremely tight timings depending on what specifically you need. And of course any specific performance critical code can be written in C and everything else can be micropython. It's great, definitely worth exploring. https://www.youtube.com/watch?v=YovngSLXoxw https://www.youtube.com/watch?v=YovngSLXoxw
- sintezcs 3y agoTrezor hardware crypto wallet is also running on micropython
- sintezcs 3y agoMoreover you can even work with the ULP co-processor from micropython using assembly directly from micropython code. https://github.com/micropython/micropython-esp32-ulp https://github.com/micropython/micropython-esp32-ulp
