II. SENSOR SECURITY
Security is paramount for the PoE-X Sensor when it comes to managing your
data and transferring it to sensors. iMonnit is the online software and central hub
for configuring your device settings. All data is secured on dedicated servers
operating Microsoft SQL Server.
Data Security on the Sensor
The fortified sensor secures your data from attackers and secures the sensor
from becoming a relay for malicious programs. Even when the sensor is at rest,
the PoE-X Sensor is designed to prevent prying eyes from accessing the data.
The Monnit PoE-X Sensor does not run on an off-the-shelf multi-function OS
(operating system). Instead it runs a purpose-specific real-time embedded state
machine that can?t be hacked to run malicious processes. It also provides no
active interface listeners that can be used to gain access to the device over the
network.
iMONNIT Security
Access is granted through the iMonnit user interface, or an Application
Programming Interface (API) safeguarded by 256-bit Transport Layer Security
(TLS 1.2) encryption. TLS is a blanket of protection to encrypt all data exchanged
between iMonnit and you. The same encryption is available to you whether you
are a Basic or Premiere user of iMonnit. You can rest assured that your data is
safe with iMonnit.
III. ORDER OF OPERATIONS
It is important to understand the order of operations for activating your PoE-X
Sensor. If performed out of sequence, your sensor may have trouble
communicating with iMonnit. Please follow the steps below to make sure
you are performing your set-up correctly.
SET-UP STEPS
1. Register your PoE-X Sensor on iMonnit.
Add your PoE-X Sensor to the iMonnit account (see page 3 for
step-by-step directions).
2. Connect the Ethernet and optional power cords to the sensor.
Plug in powered Ethernet cable. Depending on your facility, you might need
to plug in both the Ethernet cable and power cord.
3. Mount your sensor.
Place your sensor in the desired location using screws or double-sided
tape.
Note: Each step is covered in more detail in the following sections.

IV. REGISTRATION
If this is your first time using the iMonnit online portal, you will need to create a
new account. If you have already created an account, start by logging in. For
instructions on how to register for an iMonnit account, please consult the iMonnit
User Guide at https://www.monnit.com/support/documentation.
REGISTERING THE POE-X SENSOR
1. Add the sensor on iMonnit.
Add the sensor to your account by choosing Sensors in the main menu.
Navigate to the Add Sensor button.
2. Find the device ID. See Figure 1.
The Device ID (ID) and Security Code
(SC) are necessary to add a sensor.
These can both be located on the label
on the bottom of your device.
3. Adding your device. See Figure 2.
You will need to enter the Device ID
and the Security Code from your PoE-X
Sensor in the corresponding text boxes.
Use the camera on your smartphone to
scan the QR code on your device. If you
do not have a camera on your phone,
or the system is not accepting the QR
code, you may enter the Device ID
and Security Code manually.
- The Device ID is a unique number
located on each device label.
- Next, you?ll be asked to enter the Security Code on your device. A
security code consists of letters and must be entered in upper case, no
numbers. It can also be found on the barcode label of your device.
When completed, select the Add Device button.

V. SETTING UP YOUR PoE-X SENSOR
Plug in powered Ethernetcable.
Depending on your facility, you might need
to plug in both the Ethernetcable and power
cord. See Figure 3.
LIGHTING SEQUENCE
The sensor will cycle through three stages as it powers on:
Power-on stage: At this stage, the sensor will analyze electronics and
programming. The LED lights will flash red and green, before all becoming green
for one second. In the case of failure, the light sequence will repeat after ten
seconds. Please contact technical support if the lights aren?t green after two
minutes.
Connection stage: The sensor will attempt to settle all operational connections.
As the sensor attempts to connect, the Sensor Status LED will be off, waiting for
the Ethernetconnection to complete. After the Ethernetsetup is complete, the
Sensor Status Light will briefly blink red before turning green and then going off
completely. If the Ethernet Status LED is orange, there is a failure in your
Ethernetconnection. Check your connection.
Operational stage: In the operational stage, the Ethernetlights will remain active
while the Sensor Status light remains off ? unless there is an issue. See Figure 4
& Figure 5.

VI. SENSOR OVERVIEW
Select Sensors from the main navigation menu on iMonnit to access the sensor
overview page and begin adjusting your PoE-X Sensors.
MENU SYSTEM
Details - Displays a graph of recent sensor data
History - List of past readings
Actions - List of actions attached to this sensor
Settings - Editable levels for your sensor
Calibrate - Reset calibration for your sensor
Scale - Change the scale of readings for your sensor
Directly under the tab bar is an overview of your sensor. This allows you to see
the signal strength of the selected sensor. A colored dot in the left corner of the
sensor icon denotes its status:
- Green indicates the sensor is checking in and is within user-defined safe
parameters.
- Red indicates the sensor has met or exceeded a user-defined threshold or
triggered event.
- Gray indicates that no sensor readings are being recorded, rendering the
sensor inactive.
- Yellow indicates that the sensor reading is out of date, possibly due to a
missed heartbeat check-in.
Details View
The Details View will be the first page you see upon selecting which sensor
you would like to modify. See Figure 7.

Readings View
Selecting the Readings Tab within the tab bar allows you to view the sensor?s
data history as time stamped data.
- On the far right of the Sensor History Data is a cloud icon. ( )
Selecting this icon will export an Excel file for your sensor into your
download folder.
The data file will have the following fields:
MessageID: Unique identifier of the message in our database.
Sensor ID: If multiple sensors are exported, you can distinguish between the
sensors using this number ? even if the names are the same.
Sensor Name: The name you have given the sensor.
Date: The date the message was transmitted from the sensor.
Value: Data presented with transformations applied, but without additional
labels.
Formatted Value: Data transformed and presented as it is shown in the
monitoring portal.
Raw Data: Raw data as it is stored from the sensor.
Sensor State: Binary field represented as an integer containing information
about the state or the sensor when the message was transmitted. (See
?Sensor State?explained below.)
Alert Sent: Boolean indicating if this reading triggered a notification to be sent
from the system.
Sensor State
The integer presented here is generated from a single byte of stored data.
A byte consists of 8 bits of data that we read as Boolean (True (1) / False (0))
fields.
Using a temperature sensor as an example:
If the sensor is using factory calibrations, the Calibrate Active field is set True
(1) so the bit values are 00010000 and it is represented as 16.
If the sensor is outside the Min or Max Threshold, the Aware State is set True
(1) so the bit values are 00000010 and it is represented as 2.
Note: Make sure you have the date range for the data you need input
in the ?From? and ?To? text boxes. This will be the previous day by
default. Only the first 2,500 entries in the selected date range will be
exported.

If the user has calibrated the sensor, the Calibrate Active field is set False (0)
and the sensor is operating inside the Min and Max Thresholds, the bits look
like 00000000 ? this is represented as 0.
If the sensor is using factory calibrations and it is outside the threshold, the bit
values are 00010010 and it is represented as 18 (16 + 2 because both the bit
in the 16 value is set and the bit in the 2 value is set).
Settings View
To edit the operational settings for a sensor, choose the Sensor option in
the main navigation menu and then select the Settings Tab to access the
configuration page. See Figure 8.
A. Sensor Name is the unique name you give the
sensor to easily identify it in a list along with any
notifications.
B. The Heartbeat Interval is how often the sensor
communicates with the server if no activity is
recorded.
C. Aware State Heartbeat is how often the sensor
communicates with the server while in an Aware
State.
D. Assessments per Heartbeat is how many times
between heartbeats a sensor will check its
measurements against its thresholds to determine
whether it will enter an Aware State.
E. Below is the minimum reading the sensor should
record before entering an Aware State.
F. Above is the maximum reading the sensor should
record before entering an Aware State.
G. The Aware State Buffer prevents the sensor
from bouncing between Standard Operation and
Aware State when the assessments are very close
to a threshold. For example, if a Maximum Threshold
is set to 90° and the buffer is 1°, then once the
sensor takes an assessment of 90.1° it will remain in
an Aware State until dropping to 89.0°. Similarly at
the Minimum Threshold the temperature will have to
rise a degree above the threshold to return to
Standard Operation.
H. In small sensor networks, the sensors can be set
to synchronize their communications. The default
setting ?Off?allows the sensors to randomize their
communications, maximizing communication
robustness. Setting this will synchronize the
communication of the sensors.
