    Channel Type Value
    03 67 Temperature: 1001=> 0110 = 272/10=27.2°C
    04 68 Humidity: 71 => 113/2=56.5 %RH
    05 7d

    CO2: cd 04 => 04 cd=1229 ppm
    06 73

    Barometric Pressure: 51 27=>27 51=10065/10=1006.5 hPa
  2. Battery level: report when the device joins the network or every 24 hours.
    017564
    Channel Type Value
    01 75 Battery: 64=>100%

Alarm Report

The device supports to report below types of alarm report packets.
  1. Threshold alarm or alarm dismiss. The alarm report format is the same as periodic report.
