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
• Windows 10: Bluetooth LE Explorer

The code was tested with MicroPython V1.15 on ESP32 (build esp32-20210418-v1.15.bin) with Mi Flora Firmware V3.2.2
