# MicroPython-MiFlora

MicroPython library for Xiaomi Mi Flora (aka. flower care) BLE¹ plant sensors

¹ BLE: Bluetooth Low Energy

The library reads the following data from the device:

- firmware version

- battery level

- temperature

- light intensity

- moisture

- conductivity

The sensors' BLE MAC addresses must be supplied by the user

in the variable *miflora_sensors*.

Example:

```

# MAC addresses of two Mi Flora sensors

miflora_sensors = [ 

    bytes(b'\xC4\x7C\x8D\x66\xA5\x3D'),

    bytes(b'\xC4\x7C\x8D\x66\xA4\xD5')

]

```

The MAC addresses can be found as follows:

- Linux: `$ sudo hcitool lescan`

- Android: [nRF Connect for Mobile](https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp)

- Windows 10: [Bluetooth LE Explorer](https://www.microsoft.com/en-us/p/bluetooth-le-explorer/9n0ztkf1qd98)

The code was tested with MicroPython V1.15

on ESP32 (build esp32-20210418-v1.15.bin)

with Mi Flora Firmware V3.2.2

MicroPython-MiFlora is based on the following code and documentation:
