Presentation


The IN’O sensor is a LoRaWAN class A sensor that manages two different power supplies: one is external and may range from 9V to 24V, the other one is internal on the battery.

The IN’O sensor incorporates 10 digital inputs, and 4 optocoupled outputs. It also includes an external antenna.

The level or a counter can be transferred to the different inputs. It is also possible to get the voltage of the power supply, and to switch ON, OFF or toggle the outputs.

50-70-087-xxx Class C

 

Electronic input/output

The schematic of the different inputs and outputs of the IN’O sensor is illustrated below:

→ Due to software limitation, the maximum frequency is 100 Hz on each input

Electrical schematic example for outputs

On the output, there is a 3V voltage drop. The maximum current is 100mA (or maximum power of 1.5W):

Installation and operation


Installation

The housing is intended to be installed inside or outside a building but it must be protected from vertical water spray and direct sunlight.

The product is delivered disassembled. This enables the connection to the screw terminals.

Before connecting your cable strands to the product’s screw terminals, you must insert the cable gland’s nut and the seal.

 

cable-gland2

Then connect the wires to the Inputs and Outputs that will be used:

ino_carte

For the connectors, we recommend using several 20-26 AWG single wires. As the connectors pinch the wires plugged inside approximately 4mm from the wire end, strip the wires over a length of approximately 5 to 6mm before plugging them into the connectors.

For Inputs from 7 to 10, the connectors shown in the following pages can be used:

 

Once the assembly is complete, the casing can be closed.

The housing is compatible with the following DIN rail adapter:

Radio propagation

In order for the sensor to operate correctly, the number of obstacles should be limited in order to avoid excessive radio wave attenuation. It is also important to place the sensor as high as possible. Also, the antenna needs to be directed upwards.

Autonomy


The information in the table below represents how long the battery can last. It is based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12.

The disposable battery has a 3.6Ah capacity, of which 85% is used.

A value of 3µA of consumption is added per input connected (contact closed).

When one of the outputs is ON, a consumption of 160µA is added. Due to this consumption, it is highly recommended to use an external power supply.

Human Machine Interface


Once the device is installed, switch the power ON.

There are three LEDs on the IN’O devices:

ASSN:      blinking until the association with a network is done.

association

FNC:     blinking every minute while an input is activated.

CNF:     blinking in configuration mode.

  • A user button is available to enter the configuration mode. « Void » frames are then sent every minute for 10 minutes.

Standard reports are disabled in this mode.

Configuration mode
Way to trigger itOne press on the USER button or specific ZCL command
Way to stop it Another press on the USER button or specific ZCL command
Effects on the sensorThe CONF led (red) blinks (3 sec. OFF, 3 sec. ON) and the sensor sends an uplink frame every minute. The blinking is illustrated below this table.
DurationThe configuration mode lasts 10 minutes when it is triggered by pressing the USER button

  • A reassociation procedure can be requested if no downlink frame is received by the sensor during a given periodicity (4 days by default) or if a given number (100 by default) is reached or in case of failure (no acknowledgement received) by sending an applicative frame to the sensor or via the sensor’s IHM.

The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate…) are lost.

ReAssociation Mode
Way to trigger itThree short presses on the USER button or ZCL command from LoRaWAN cluster.
Effects on the sensorThe ASSO LED (green) blinks as the “no commissioned sensor” LED is lit.
  • A factory reset is available on nke Watteco’s sensors. It deletes all the applicative settings saved in the flash memory (i.e.: configured batches and reports will be deleted).

The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost.

Factory reset
Way to trigger itTwo short presses and one long press for approximately 7 seconds on the USER button.
Effects on the sensorThe CONF LED (red) and ASSO LED (green) blink at the same time briefly. All the applicative settings (for batches and reports) are deleted. The blinking is illustrated below this table.

The IN’O device implements “ON/OFF” and “Binary Input” clusters, associated to their Outputs and Inputs. The corresponding clusters between the connectors and the EndPoint are shown below:

0x0006ON/OFFAll

Default configuration

A default configuration is set:

  • The device reports each day the counter value associated to input 1+/1- (EndPoint 0 / Cluster Binary Input / Attribute Count).
  • The device reports the state of input 2+/2- at each variation with a hysteresis of 2 hours (Endpoint 1 / Cluster Binary Input /Attribute Present Value).

Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12)

Frame examples


All frames have to be sent on port 125

Batch report

Configuration

 

• Configure a batch report on connector input 6+/6- and connector input 5+/5-:

Timestamp and record the input 6+/6- every 100 pulses, and timestamp and record the level of input 5+/5-. A report has to be sent at least every 10 minutes:

→A counter on Input 6+/6- is the End Point 5, Cluster “Binary Input” is 0x000F, and Attribute “Count” is 0x0402.

A level on Input 5+/5- is End Point 4, Cluster “Binary Input” is 0x000F, and Attribute “Present Value” is 0x0055.

There are two different measurements to be recorded in the batch, so the tag size has to be 1. Label 0 can be used for counter and Label 1 for level.

For counter, the delta is 100 and resolution 1. For level, the delta is 1 and resolution 1. The maximum has to be configured for all to 0x800a.

Two frames must be sent to configure this batch.

Label numberTag labelTag size
1 or 20/11

To decode the batch reception, use br_uncompress. Type for binary input attribute counter is U32 (10), type for binary input attribute PresentValue is Boolean (1). Hence the following command must be used:

echo “ 26100040405e7692050000004006 ” | br_uncompress -a 1   0,1,10   1,1 ,1
