Warnings ............................... 13 Manufacturer ..............................13 Introduction The Kombi-LoRaWAN is an economical multi-sensor indoor air quality (IAQ) transmitter developed from the Kube-RHT series. Kombi-LoRaWAN measures temperature, humidity, total volatile organic compound (TVOC) concentration, differential pressure and carbon dioxide (CO2) concentration. Kombi-LoRaWAN uses LoRaWAN for communication with the cloud. -
Page 3: Installation
Mount the wall holder with two universal countersunk screws (ST 2.5 or ST 3.0). Use applicable length depending wall material. In correct orientation, the wall holder has its hooks pointing upwards. Attach the Kombi-LoRaWAN to the holder. • Place the Kombi-LoRaWAN on any surface with the bottom facing down. - Page 4 The Kombi-LoRaWAN works with its default settings and no parameter configuration is normally required. However, if it is necessary to change the settings of the device, it can be done with Nokeval’s MekuWin software (available for free at www.nokeval.com). Following procedure should be followed in order to get access to the settings: •...

An auto calibration is necessary for the sensor. Without it, the sensor will drift over time and eventually give incorrect readings. The auto calibration can work properly only if the Kombi-LoRaWAN is exposed to a fresh air at least some hours during each week. In practice, the room must be unoccupied, and its ventilation must be switched on. -

MAC layer controls the data rate. Uplink payload structure This information is only relevant for integrating the Kombi-LoRaWAN with customer’s own cloud platform. The payload data format consists of a protocol version field and 1 or more messages in length-type-data format. - Page 7 Message format: Size Name Meaning Message length Bits 0:6 - Message length in bytes, excluding length field and optional age field. Bit 7: If 1, age field is included. (2B) Optional age field Age, uint16 * 60 seconds Message type Type, e.g.
- Page 8 Type 11: Utility Contains utility information about the device. Uses bit flags to describe which fields are included in the message, similar to message type 10. Size Name Meaning Bit flags If 0x00: Request to send utility. Otherwise describes which fields are included in the message. E.g. 0100 0001 = device type + serial number 0 –...
- Page 9 Example uplinks Here are some example uplinks to help clarify how the uplink payloads are structured. Bytes are presented as hex values, numbers are LSBF. E.g. consecutive bytes 0x01 and 0x23 converted to unsigned int16 equals 0x01 + 0x23*0x100. Example – normal measurement data Bytes (hex): 01 0E 0A 01 00 3B 98 09 B0 0B AD 0D E3 FB 78 05 00 Interpretation: Bytes (hex)
