1. PRODUCT OVERVIEW
1.1. General description
The Adeunis COMFORT Serenity is a ready-to-use IoT sensor that meets the needs of users for
indoor monitoring of temperature, ambient humidity, carbon dioxide (CO2) concentration, and
relative changes in volatile organic compounds (VOCs) levels. This product is also equipped with
an NFC interface, which allows for quick and easy configuration with a smartphone.

User Guide | COMFORT SERENITY LwM2M | NB-IoT / LTE-Cat-M1ca 5
Thermal comfort and indoor air quality 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 Serenity 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, humidity, CO2, and
VOC 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 up to10
years without maintenance (device configuration : 1 sampling every 60 mins, 1 transmission every 60
mins, LEDs enabled).
1.2. Features
4-in-1 Sensor: Temperature, humidity, CO2 concentration, relative changes in VOC levels
User Notification: Product equipped with a visual indicator (LED) on the casing
Global Cellular Compatibility: LTE-Cat-M1 and NB-IoT
Simplified Application Configuration: Remotely or locally via the NFC IoT Configurator
application

User Guide | COMFORT SERENITY LwM2M | NB-IoT / LTE-Cat-M1ca 6
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 Serenity 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

📌
NOTE
Users have the option to adjust the power of the LEDs to optimize the product's battery life.
Four operating modes are available:
LEDs OFF
LEDs FULL: All three LEDs operate at 100% power.
LEDs ECO: LEDs operate at 50% power.
LEDs ECO+: LEDs operate at 30% power.
By default, the product is configured with the LEDs operating at 100% power. Changing the
LED operating mode is possible via NFC.
Changing the LED operating mode via NFC using the NFC IoT Configurator
application:
Go to the "LED" section in the "CONFIGURATION" menu of the sensor => Select the
desired LED operating mode => Apply the new configuration to the product via NFC.
1.8. Power supply
1.8.1 Power source
The COMFORT Serenity 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
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.
