Reminder regarding LoRaWAN mode
LoRaWAN technology is bidirectional, and allows:
Transmission of frames from the sensor to a network (uplinks)
Transmission of information from the network to the sensor (downlink)
End-to-end encryption of data exchanged (AES128)
When used in LoRaWAN mode, the sensors can send their data to a public (operator) or private LoRaWAN (gateway) network.
More information about Enless sensors and their behavior
LoRaWAN class : class A Frequencies used: 3 frequencies can be used: 868.100 MHz, 868.300 MHz, 868.500 MHz. LoRaWAN version : V1.0.2revB Activation : OTAA Activation keys : DEVEUI, APPEUI, APPKEY
LoRaWAN class : class A Frequency used: 64 frequency channels can be used. The frequency spectrum of these channels starts at 902.3 MHz and increases linearly by 200 kHz, reaching 914.9 MHz. LoRaWAN version : V1.0.4 Activation : OTAA Activation keys : DEVEUI, APPEUI, APPKEY
EU 868 products:
When powered up, the transmitters perform a JOIN request.
After 24Hr , they send a LinkCheckReq message that needs to be confirmed with a LinkCheckAck. And so on every 24 hours. When the LinkCheckReq has been confirmed with a LinkCheckAck, the transmitter will not send another JOIN request.
If the LinkCheckReq message does not receive a LinkCheckAck response, further LinkCheckReq messages will be sent. If 6x LinkCheckReq messages do not receive a response, the transmitter will then initiate a new JOIN procedure.
US915 products:
When powered up, the transmitters perform a JOIN request.
After 37 hours, they send a LinkCheckReq message which should be confirmed by a LinkCheckAck. And so on every 37 hours. As long as the LinkCheckReq are confirmed by a LinkCheckAck, the transmitter will not send a new JOIN.
If the LinkCheckReq message does not receive a LinkCheckAck response, then new LinkCheckReq will be sent in the process. If 6x LinkCheckReq, spaced by the periodicity with which the transmitter is configured, receive no response, then the transmitter initiates a new JOIN procedure. If the JOIN procedure is not successful, the transmitter will enter sleep mode and reinitiate a JOIN procedure after 37 hours.
For EU 868 products, when the transmitter initiates a JOIN request for the first time, the Spreading Factor is fixed at SF12 and BW125. The transmitter will not change its SF unless it receives a LinkADRReq from the gateway, requesting it to use a different SF parameter
Power the sensors so they pair with the LoRaWAN network.
Once the transmitters have been declared using the keys on the cloud or the gateway, the LoRaWAN transmitters must be powered up to dialogue with the network.
Verify that the transmitters are in LoRaWAN mode. Validate that the jumper of each transmitter is correctly positioned on a single pin and that it is in LoRaWAN mode (see appendix). If this is not the case, please position the jumper correctly before proceeding with product activation.
Using downlinks to configure sensors
The Enless sensors listen for downlinks after each uplink is sent. If you configure a downlink from the cloud or the gateway, the transmitter should retrieve it immediately after sending an uplink frame and change its settings accordingly.
To edit your configuration downlinks, we provide you with the following file:
Downlinks are to be sent on port 1.
Position and secure the sensors in their final locations
Once you have validated that the sensors are paired and communicating with the LoRaWAN network, you can proceed to their installation.
The correct positioning of sensors is very important and significantly influences the quality of radio wave propagation. If your sensor is poorly positioned, you will reduce the radio coverage distance. To maximize transmitter performance, please follow the points described below:
Position the sensors as high as possible
We recommend positioning the transmitters at a minimum height of 1.50m
Make sure the transmitter antenna is always pointing upwards
The sensors are fixed using wall mounting lugs. These lugs are intended for fixing by screw. The lugs of the room sensors (white boxes) are located inside the sensors. For rugged sensors (grey housings), you can also use the mounting collar passages on the sides of the housing.
Declare sensors on your LoRaWAN network
LoRaWAN Enless sensors use OTAA (Over The Air Activation) activation mode.
For their OTAA activation, Enless sensors have LoRaWAN keys:
• DEVEUI : Transmitter identifier • APPEUI : Global application identifier • APPKEY : Transmitter application key
These activation keys are made available in three possible ways:
1 - On the labels on the back of the sensors
2 - By scanning the QR codes of the sensors
3 - In CSV format
The activation keys for your LoRaWAN Enless sensors can be provided in .csv format by our Sales Administration department.
Please contact adv@enless.fr
Validate that messages are correctly received on the LoRaWAN network
Before moving on to the installation and fixing of the products, we invite you to validate from the cloud or the gateway that the sensor frames are received, and at the correct frequency.
If necessary, a push button to force the sending of test frames is available on the electronic card of each transmitter.

LoRaWAN vs LoRa proprietary
This document described the procedure for installing sensors in LoRaWAN mode. The sensors you use must therefore communicate in the LoRaWAN mode.
The communication mode is selected by means of a jumper on the electronic board in each sensor. See example below
Example below :
The mode change will only be taken into account if the jumper switching is carried out when the sensor is depowered.
TX CO2 COV T&H AMB 600-023/ TX CO2 T&H AMB 600-123
The TX CO2 VOC T&H AMB 600-023 sensors are delivered pre-calibrated.
You can re-calibrate them manually on a “fresh-air” basis if you notice a shift in the CO2 values measured over time. To ensure the best possible calibration, we recommend that you calibrate the products by following the procedure below:
We recommend that you press the push button using a screwdriver or pen so as not to damage the CO2 sensor with your finger.
Connecting smart metering sensors to meters
Raccordement de votre sonde 4/20mA au transmetteur TX 4-20 600-035
The TX 4/20 transmitter is delivered without analog probe.
To connect your 4/20mA probe to the sensor, open the sensor housing and refer to the label located inside the transmitter under the terminal block for connection.
Powering your 4/20mA probe by the sensor is only possible if your probe can be powered with less than 3V.
When the sensor is powered, position it on a table near a window, the window must be open so that the air in which the transmitter will calibrate is healthy.
Press the push button located on the transmitter electronic board for 15 seconds. Only release the pressure when LEDs L1, L2, L3 light up. This means that the calibration process has been activated.
Walk away from the sensor and let the calibration take place. The process takes approximately 3 minutes.
When the LEDs stop flashing, this means that the calibration is complete. You can take the sensor and install it in its final location.
Installing the optical read head on the meter
The pulse optical reader records 1 pulse every 5 flashes.
Calculation formula = (A x 5) x B x C x D
A = Number of pulses measured
B = Pulse weight Blue tariff: 0.1W/pulse. In this case, enter 0.1 for B value in the calculation below. Other tariffs: Shown on the meter’s interface (label or screen)
C = TC ratio (Current transformation) Blue tariff: 1
Yellow tariff: 20, 40 or 100 (shown on the meter’s interface)
D = TT ratio (Tension transformer)
Blue tariff: 1
Yellow tariff: 1 Green tariff: Shown on the meter’s interface.
The calculation formula above is a calculation of consumption in Watt-hour (Wh). To get a value in Kilowatt-hour (kWh), you just need to divide the value by 1,000
Below is a table showing the battery reference to use for each sensor.
