Equipement / IIoT device association
Once connected to Wi-Fi, the IIoT device must be associated with an existing equipment in ALIX. Within the selected equipment's interface, in the IIoT configuration section (Figure 1 : 1), select the device from the "IIoT module" drop-down menu. The device is identified by its serial number, visible inside the case, behind the battery (Figure 2).

Parameter definition
Once the IIoT device is associated to the equipment, ON/OFF thresholds and delays must be defined. Live current values are converted into ON/OFF states by the smart sensor using the settings shown in Figure 3.
Figure 3 : IIoT settings
- ON threshold represents the current threshold past which the equipment is considered to be ON ;
- ON Delay represents the delay for which the equipment's current must be over the ON Threshold before the ON event is triggered;
- OFF Threshold represents the current threshold under which the equipment is considered to be OFF ;
- OFF Delay represents the delay for which the equipment's current must be under the OFF Threshold before the OFF event is triggered;
In order to determine the proper thresholds and delays for a specific equipment, the real-time values read by the IIoT device can be viewed by clicking on the following button
, which is located in the upper right-hand corner of the IIoT settings interface (Figure 3). This allows to view the current graph produced by a typical usage cycle of the equipment and to determine the parameters accordingly. An example graph is shown in Figure 4. When this interface is open, live reading is turned on by pressing the red "record" button, and is turned off by either pressing the button again or closing the pop-up overlay.

In the example shown in Figure 4, spiked visible at 15:47:29 and at 15:48:29 are considered indesirable (e.g. failed start), whereas the curve between 15:49:30 and 15:51:20 represent a real equipment cycle. Figure 5 shows an example of settings that would correctly recognise the ON/OFF states in this situation:
Figure 5 : Settings example
When settings are modified, the following button
will flash, which means that the new configuration is awaiting to be sent to the IIoT device. When clicked, it will show the following confirmation message:

After this step, the IIoT device is fully operational. Equipment runtime monitoring is viewed in the bottom area of the ALIX Equipments interface (Figure 1 : 2).
Figure 7 shows, for the selected time range, the following elements:
- IIoT device (identified by serial number) connection timeline: green when the device is connected and operational, red when the device is unavailable;
- Equipment state timeline: ON states detected by the IIoT device (yellow) vs. usage time defined in ALIX from board operations.
