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.
Thermal comfort and indoor air quality data are transmitted via a cellular IoT network
(NB-IoT or LTE-Cat-M1) to a MQTT broker. No additional equipment (gateway,
router, etc.) is required for data transmission.
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 MQTT protocol.
The product is powered by a replaceable battery pack and has been designed to
work for up to 9 years without maintenance (device configuration : 1 sampling every
60 mins, 1 transmission every 60 mins, LEDs enabled).

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).

User Guide | COMFORT SERENITY MQTT | NB-IoT / LTE-Cat-M1 12
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.
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 locally through the NFC IoT
Configurator application or the LED display.
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:

User Guide | COMFORT SERENITY MQTT | NB-IoT / LTE-Cat-M1 13
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
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.

User Guide | COMFORT SERENITY MQTT | NB-IoT / LTE-Cat-M1 14
CAUTION: Press gently to avoid damaging the enclosure
2. Remove the current battery and replace it with the new one, making sure to
observe the polarity indicated on the electronic board and the battery model.

User Guide | COMFORT SERENITY MQTT | NB-IoT / LTE-Cat-M1 15
3. To close the enclosure, insert the bottom of the front panel first and snap the top
of the enclosure
After this battery replacement procedure, the product will automatically resume its
"normal" operation and clear the low battery indicators (status and LED).
1.8.4 Connecting the external power supply
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
