Table of contents

1. General description

This chapter describes the structure of the telemetry data. The number of bytes in the payload depends on the configuration of the sensor. The structure of the data depends on which sensors are present in your product.

In principle, each version has a header. This header contains information about the version and status of the sensor and also contains a master measurement value. This measurement value can simply be assumed to be the current measurement value.

The header is followed by an additional payload section that contains further information, such as special parameters for the measurement principle or settings for position and opening detection. Not every sensor has an additional payload section.

2. Terminology

Term Description
Byte No. Byte number starting at 1
Alias Comprehensible name of the variable
Description Description of the variable
Designation Designation in the data converter
Unit Unit of the variable
Data hub .json key Key in the .json file when using the data hub

3. Structure of the module key

Byte 1 Byte 2
Bit 7 – 4 Bit 3 – 0 Bit 7 – 4 Bit 3 – 0
Base ID module
e.g. Sentiface, Senticom, Sentivisor 		Major version
(SW/HW version) 		Minor version
(SW/HW version) 		Product version
(sensors, e.g. TH, THL, ACC, etc.)

The module key of the SENTIFACE module can be taken from the first 2 bytes of each uplink. The module key is required for the downlink.

5. Port assignment for WIFI SSID SCAN payload, GNSS SCAN payload and regular payload

Feature LoRaWAN port Description
GNSS Scan Payload 192 Raw data (satellite ID, time, etc.) is sent to the geolocation backend.
WIFI SSID Scan Payload 197 Scanned MAC addresses and RSSI data are transmitted for location tracking.
Regular telemetry data 1 Regular payload data of the sensor, such as temperature, relative humidity, angle, battery voltage, etc.

Example of the WIFI SSID scan payload:

6. Decoding of WIFI SSID SCAN and GNSS scan data

The following providers can be recommended for decoding WIFI SSID SCAN and GNSS SCAN data:

  • Semtech LoRa Cloud (discontinued at the end of July 2025)
  • AWS
  • Tencent
  • Traxmate
  • Sentinum

Local databases can be used for on‑prem applications.

7. LoRaWAN payload field description

Byte number Alias name Description Unit Designation in payload decoder Module key Datahub .json key
1 – 2 Module key Byte 1:
4 bits MSB: Module code. For Mioty, exclusively "Sentiface" telemetry module, i.e. always 0x1.
4 bits LSB: Major version. Firmware with the same major version but higher minor version remains compatible with older decoders. However, the number of bytes may change.

Byte 2:
4 bits MSB: Minor version. New software versions may incrementally add new telemetry to the data packet.
4 bits LSB: Sub / product version. For Helios, these bits encode the specific configuration of the connected sensors. 		module_key XXX1 module_key
3 Uplink counter Protocol‑independent uplink counter that increments up to a maximum value of 255. After that, the counter starts again at 0. uplink_counter XXX1 uplink_counter
4 – 5 Battery voltage Current battery voltage in millivolts.
Voltage in volts calculated as:
battery_voltage = (dataBytes[3] << 8 | dataBytes[4]) / 1000.0 		mV battery_voltage XXX1 battery_voltage
6 Internal temperature Temperature of the sensor controller.
internal_temperature = bytes[6] - 128
For this sensor, the value represents the controller temperature and is an approximate value with an accuracy of ±2 °C. 		°C internal_temperature XXX1 internal_temperature
7 – 10 Operating time Operating time in seconds until reset via command or battery replacement. operating_seconds XXX1 operating_seconds
11 – 14 Cycles Number of cycles indicating how often the machine has been started or activated. cycles XXX1 cycles
15 – 16 ON/OFF rate Ratio between ON time and OFF time since the last uplink, e.g. 10 (/100) → 0.1 %. utilization_rate XXX1 utilization_rate
17 Activity Indicates whether an activity has been detected. is_active XXX1 is_active
18 – 19 Temperature Exact temperature value calculated as:
decoded.temperature = ((bytes[idx++] << 8) | bytes[idx++]) / 10 – 100
ONLY FOR TH VERSION 		°C temperature XXX1 temperature
20 Relative humidity Relative humidity.
ONLY FOR TH VERSION 		%RH humidity XXX1 humidity
