1. PRODUCT OVERVIEW
1.1. General description
The Adeunis COMFORT is a ready-to-use IoT sensor that meets the needs of users for indoor
monitoring of temperature and ambient humidity. This product is also equipped with an NFC
interface, which allows for quick and easy configuration with a smartphone.
Thermal comfort data are transmitted via a cellular IoT network (NB-IoT or LTE-Cat-M1) to a server.
No additional equipment (gateway, router, etc.) is required for data transmission.
The COMFORT integrates the LwM2M (Lightweight Machine to Machine) standard, which enables
users to achieve integration and maintenance savings, reduce deployment costs, strengthen sensor
fleet security, and optimize product battery life.
The product operates autonomously and intermittently. It measures temperature and humidity data
from the onboard sensors in "sleep" mode (PSM) and stores the data in its local memory. It then
wakes up at preconfigured intervals to transmit the stored data using the LwM2M protocol.
The product is powered by a replaceable battery pack and has been designed to work for over 15
years without maintenance (device configuration : 1 sampling every 60 mins, 1 transmission every 60
mins, LEDs enabled).

1.2. Features
2-in-1 Sensor: Temperature, humidity
Global Cellular Compatibility: LTE-Cat-M1 and NB-IoT
Simplified Application Configuration: Remotely or locally via the NFC IoT Configurator
application
Data Transmission Modes: Periodic and/or event-based (threshold exceeded and/or threshold
fallen below)
Error/Fault Management: Configuration error, low battery
Data Timestamping: UTC timestamp, remote synchronization via the network
Remote Operational Maintenance: LwM2M defines all device management operations for a
sensor fleet (command sending, configuration read/write, firmware update)
Multi-Platform Integration: Product data format standardization (LwM2M) that IoT platforms can
interpret without the need for specific development
Bootstrap Support: Allows the product, when powered on for the first time (or after a factory
reset), to download its secret codes and configuration
Battery-Powered Autonomous Product: Powered by a replaceable internal dual-battery pack
designed to operate for multiple years without replacement (refer to the autonomy table). The
product can also be powered by an external power supply (not provided with the product).
Autonomy Optimization: Data logging and blackout (deactivation of data transmission for a
given period)
Made in France: Product designed and manufactured in France

NOTE
To address different use cases, the COMFORT product also supports the MQTT (Message
Queuing Telemetry Transport) communication protocol.
To use the product with the MQTT protocol, refer to the dedicated User Guide.
1.3. Package contents
The product is delivered in a cardboard packaging containing the following components: Front face,
back face, electronic board, and ER18505H-2 dual battery pack.

1.8. Power supply
1.8.1 Power source
The COMFORT can be powered by a double-pack of FANSO Li-SOCl2 ER18505H-2 batteries or by
an external power supply connected to a 2-pin terminal block (external power supply not provided).
When both batteries and external power supply are used simultaneously, the external power
supply takes priority.
When the external power supply is used, the product operates with the same cycle as when
powered by the double-pack batteries (PSM mode).
The certified external power supply recommended by Adeunis for use with the product is GS05E-USB
- Wall Mount AC Adapters 5W 5V 1A W/Euro Plug WallMount USB Output from Mean Well.
If another external power supply model is selected to work with the product, it must strictly adhere to
the electrical specifications mentioned above and comply with the standards EN/IEC 62368-1 and EN
1.6. Push button
User Guide | COMFORT LwM2M | NB-IoT / LTE-Cat-M1 9
61000-3-2, EN 61000-4-2, EN 61000-4-4, EN 61000-4-5. The user must independently verify the
compatibility of this power supply with the product.
1.8.2 Low Battery Management
1.8.2.1 Detection mode
When the product detects that the battery is not capable of delivering the required energy for
transmission (due to extreme temperatures or end of battery life), it waits until it is capable of
transmitting. If it detects that the delay exceeds 1 minute, it notifies the user that the battery level is
low.
1.8.2.2 User information
The user can be informed of the product's battery status either locally through the NFC IoT
Configurator application or the LED display, or remotely.
The low battery indication automatically changes when the battery is replaced or when temperature
conditions are favorable for proper battery operation.
User Information through visual indication on the product's LEDs:
The red LED flashes every 60 seconds for 500 ms if the product's battery level is low.
User Information through the NFC IoT Configurator application:
📱
Go to the "DIAGNOSTIC" section of the sensor to
check the battery status as "OK" or "LOW
User Guide | COMFORT LwM2M | NB-IoT / LTE-Cat-M1 10
User Information through an LwM2M server:
The LwM2M server can request the product to report its battery status. To do this, the user needs to
trigger a READ operation on the "error code" resource via the server, which will return the current
value of this resource, or an OBSERVE operation can be initiated.
URI Object name Resource Name Access type Unit Description
/3/0/11 Device Error code R - 0= No error 1=
Low battery
1.8.3 Changing the double battery pack
When the low battery indicator is activated, it is possible to change the internal battery pack of the
enclosure.
It is important to use the same battery reference, namely ER18505-2.
PROCEDURE FOR CHANGING THE DOUBLE BATTERY PACK:
1. Insert a flathead screwdriver tilted towards the front of the enclosure into the opening at the top
and press. The enclosure will open in two and the front panel will detach.
