This is a Python3 library to allow interrogation of Xiaomi Mijia LYWSD* sensors via Bluetooth Low Energy (BLE).
Note: This is an unofficial project, and is in no way supported or endorsed by Xiaomi.
This module requires bluepy3 which should be installed automagically when using the installation instructions below.
Development of this package is done in Python 3.11. The package is considered forwards compatible at least upto Python 3.12 and probably also beyond. Backwards compatibility is not guaranteed; if it works on Python 3.9 or before consider yourself lucky. Python versions that are end-of-life are not supported.
The package has been extensively tested on a Raspberry Pi 3 Model B+ (aarch64) with Debian GNU Linux 12 /w Python 3.11.*.
pip install pylywsdxx
import pylywsdxx as pyly
mac = "A4:C1:38:0D:EA:D0"
device2 = pyly.Lywsd02(mac)
data2 = device2.data
print(f"Temperature: {data2.temperature}°C")
device3 = pyly.Lywsd03(mac)
data3 = device3.data
print(f"Temperature: {data3.temperature}°C")
Please note that this module has completely and intentionally broken backwards compatibility with previous
and existing versions of lywsd02 and lywsd03mmc and with v1.* versions of itself.
Based on previous work stolen from Mikhail Baranov (h4) : lywsd02
and Duncan Barclay (uduncanu) : lywsd03mmc
