      Byte: 1-2
      Alias: Module key
      Description: module_key
      Valid for versions: All - basic payload, valid and available for all sensors of the Febris series
      Description:
      Byte 1

      • 4-bit MSB: Module code. For Mioty only telemetry module "Sentiface", i.e. always 0x1.
      • 4 bit LSB: Major version. FW with the same major version but a larger minor version remain compatible with older decoders. However, the number of bytes may change!

      Byte 2

      • 4 Bit MSB: Minor version. New SW versions can gradually add new telemetry to the data packet.
      • 4 bit LSB: Sub/product version. In Helios, these bits encode the specific configuration of the connected sensors.

      Byte: 3
      Alias: Uplink Counter
      Description:  uplink_counter
      Valid for versions: All - basic payload, valid and available for all sensors of the Febris series
      Description:  Protocol independent uplink counter that reaches a maximum value of 255. After this, the counter starts again at 0.

      Byte: 4-5
      Alias: Battery Voltage
      Description:  battery_voltage
      Valid for versions: All - basic payload, valid and available for all sensors of the Febris series
      Description: Current battery voltage in millivolts
      //Voltage in volts battery_voltage: (dataBytes[3] << 8 | dataBytes[4])/1000.0,

      Byte: 6-7
      Alias:  Internal temperature
      Description:  internal_tempeterature
      Valid for versions: All - basic payload, valid and available for all sensors of the Febris series
      Description: Temperature of the sensor: Internal_temperature = ((bytes[5] << 8) | bytes[6]) / 10 - 100;

      Byte: 8
      Alias: Rel. Air humidity
      Description:  humidity
      Valid for versions: All - basic payload, valid and available for all sensors of the Febris series
