[songzh96]

Model: cgllc.airmonitor.b1

Firmware: 3.5.7_0094

Error: ** No response from the device**

This is my test code

from miio.airqualitymonitor import AirQualityMonitor

ip2 = '192.168.1.147'
token2 = '67324f4f47496353756b704a6c666f6c'
model2 = 'cgllc.airmonitor.b1'

am = AirQualityMonitor(ip=ip2, token=token2, model=model2)

if __name__ == "__main__":
    print(1)
    print(am.status())

log:
