MiFlora and LYWSD02 passive scanner

xiaomipassive

LYWSD02 and MiFlora passive scanner

Installation

git clone https://github.com/afer92/xiaomipassive.git
cd xiaomipassive
pip3 install .

class XiaomiPassiveScanner

loop = asyncio.get_event_loop()
scanner = XiaomiPassiveScanner(loop, callback, timeout_seconds=240)

callback

Function call at each received advertissement

def callback(self, data):
    print(self.dump_result(data))

Output:

mac: C4:7C:8D:65:xx:yy conductivity: 376 µS/cm
mac: 80:EA:CA:89:xx:yy light:        283 lux
mac: 15:03:10:12:xx:yy moisture:     47.0 %
mac: C4:7C:8D:65:xx:yy temperature:  20.8 °C
mac: E7:2E:01:71:xx:yy battery:      18 %

Function dump_result format the data decoded in an advertisement

Dictionnary data:

{'ok': True,
 'mac': 'C4:7C:8D:6C:xx:yy',
 'sensor': 4100,
 'stype': 'temperature',
 'svalue': ListContainer([123, 0]),
 'typeCst': ListContainer([113, 32, 152, 0]),
 'num': 247,
 'tab': 13,
 'name': 'Flower care',
 'rssi': -87,
 'value': 12.3
 }

timeout_seconds

Scan for timeout_seconds, default=240s

devices

After timeout_seconds scanning, data collected for each mac address

Function dump_device(mac) format the data for one mac address
