directly to a wall via the mounting screws.
WWW.LEVEL-SENSE.COM
07
Page 9
iii. Cable tie Mount: The two sticky pad anchors and zip ties can be used to
FREEZER SENTRY USER MANUAL
mount the head unit.
2. Temperature Sensor Install:
a. If not already done, the temperature sensor can be inserted gently into the Level
Sense (LS) Freezer Sentry head unit as shown below. Follow the labels on the
printed circuit board which will assist with inserting the sensor. There is a Green
LED that will light up on both ends of the temperature sensor when the board is
inserted correctly, and when power is applied.
WWW.LEVEL-SENSE.COM

Page 10
b. The Temperature sensor can be installed in the refigerator/freezer one of three
FREEZER SENTRY USER MANUAL
ways.
i. 1. The integrated hook can be used to mount the sensor on a wire rack as
shown on a standard freezer, or on a deep freeze.
ii. The snap lock adhesive support can be inserted into the hole on the hook
sensor. Remove the covering for the adhesive and firmly push the snap lock
support onto the refrigerator/freezer wall.

SECTION 8: CONNECT TO WI-FI
iii. To mount with the included screw, insert the
FREEZER SENTRY USER MANUAL
screw into the hole on the hook sensor, and
carefully tighten the screw to the printed
circuit board.
The Freezer Sentry device is immediately ready to join your 2.4 Ghz Wi-Fi network
after power up. When the Freezer Sentry has not been configured to a Wi-Fi network
the Cloud LED will display as WHITE, and the access point is active (the unit will
broadcast its Level Sense Wireless Network. Refer to section 6).
There are a series of articles on more advanced troubleshooting for WI-FI
connections under the Troubleshoot section which is found on the upper banner of
the website.
Password Requirements for Your Local 2.4Ghz Wi-Fi Network:
SSID (Local Network Name) and Password are Case Sensitive You must have a
password 8 - 48 Characters in Length. The following Characters are not supported
in Wi-Fi Passwords or network names at the moment: <> \ ^ ' { } “ %
THIS APPLIES TO CONNECTING WITH WPS OR CONNECTING WITH HOTSPOT!
WWW.LEVEL-SENSE.COM

Page 12
1. Hotspot Method:
FREEZER SENTRY USER MANUAL
a. To connect your Freezer Sentry to your Wi-Fi network via the hotspot mode, you
will need a Wi-Fi enabled device like a smartphone or laptop. The Cloud LED of
the Freezer Sentry should be white which indicates the device is broadcasting a
Wi-Fi hotspot. Use your Wi-Fi device (phone, tablet, or computer) to connect to
the Level Sense network (the last four digits of the Level Sense network is the
last 4 digits of the device’s MAC address). Your phone may indicate that this
network has no internet connection. This is normal.
b. Once connected to the Level Sense network, a Wi-Fi configuration page will
automatically appear. If this page does not appear automatically, then open a
web browser and enter the device’s IP address into the address bar: 192.168.4.1
c. On the webpage, you will select the bubble of YOUR HOME 2.4 Ghz Wi-Fi
network. Next you will enter the PASSWORD of YOUR HOME network. Note that
this field is case sensitive.
WWW.LEVEL-SENSE.COM

Page 13
d. Once complete, you can enter your Level Sense account email address into the
FREEZER SENTRY USER MANUAL
email address field (If you do this, the device will automatically link to your
account, and you will NOT be presented with a claim code). Lastly, press the
submit button.
e. The webpage then instructs you to click the RESET button on the Freezer Sentry.
After restarting, the Cloud LED will pulse yellow until it connects to your Wi-Fi.
Upon successful connection the device will either…
i. Present a claim code (all four LEDS on the device will blink in unison (Proceed
to Section 9)
ii. The Cloud LED will change to pulsing blue, followed by blue on the other 3
LEDs (Proceed to Section 10). This indicates that the device has been
successfully linked to your account, and no claim code is needed.
iii. The Cloud LED changes to red (No local internet connection). This can be
caused by an incorrect password for the Wi-Fi network, or the network is out
of range. If this happens, press the RESET button to try again. If it does not
connect on subsequent attempts, please reference Section 13 for instructions
on how to perform a password reset.

SECTION 9: CLAIM DEVICE
If you typed in your E-Mail address on the Wi-Fi configuration page (as seen in the
SECTION 10: CONTACT INFORMATION
FREEZER SENTRY USER MANUAL
previous Section), then your device will be claimed automatically, and it will be in
your account upon login in the portal (if you do not see the device, refresh your
screen). If you did not enter your E-Mail address on the Wi-Fi configuration page, it
will be necessary to claim the device. Once the Freezer Sentry is connected to your
wireless network, the Freezer Sentry will flash all four LEDs in unison. This is a
claim code. After logging into the portal via the website or the mobile application
click on the “Claim” button. Follow the directions on screen and enter the unique
claim code.
Once you are logged into your account on the Level Sense website, or in the mobile
application, click on the “Contacts” tab or if you are using the mobile application
click the “Notification” tab. Click on the plus button next to the default contact and
enter your phone number, cell phone service provider, etc. Do not forget to enable
both email and text options. It is a good idea to TEST both the email and text
feature currently as well. Lastly, you must save and submit the contact.

SECTION 11: NOTIFICATION SETTINGS
This section will guide you on how to enable and disable sensor inputs to suit your
FREEZER SENTRY USER MANUAL
application. On the website, you can edit the notification settings by clicking on the
bell icon, which is underneath the “Alarm Settings” column. If you are on the mobile
application, you will need to click on the device name, and then an action bar will
show up at the bottom of the screen, click on the bell icon.
1. The first input is for the Temperature Sensor. The left side of the screen has the
lower set point, and the right side is the upper set point. Any temperature below
the lower setpoint will put the device into alarm state. Also, a temperature above
the upper setpoint will put the device into alarm state. A reading that is in
between the upper and lower setpoint will not cause an alarm.
a. Delay of Temperature Alarms: This is the time for the delay of a Temperature
alarm. From the time that the temperature reading is out of range, the device
will not go into alarm state until the delay time is met. We recommend using a
delay of 5 minutes for this sensor. If you do not use a delay, then you will get
an alarm immediately if the temperature goes out of range. You may get
temperature alarms when the refrigerator/freezer are opened. This is most
likely not useful for most people.
b. Temperature Offset: The Offset feature is used to calibrate your temperature
sensor. In the first text box enter the number that you want to adjust the
temperature by. For example, if your current temperature reading from the
Freezer Sentry device is 34F, and the actual temperature in the freezer is 32F,
then you will enter 2.00 into the first text box and select the minus sign into
the operation text box to adjust the temperature reading to the correct
temperature value. Please note that it can take up to five minutes for the
offset value to take effect. Refresh your screen and refer to the Offset
Equation above to verify if the offset is applied as intended.

Page 16
2. The second input listed is the humidity sensor. The left side of the screen has
FREEZER SENTRY USER MANUAL
the lower set point, and the right side is the upper set point. A humidity reading
below the lower setpoint will put the device into alarm state. A humidity reading
above the upper setpoint will also put the device into alarm state. Note that the
humidity sensor does not have an offset function.
3. The third and fourth inputs on the screen are for a float and leak sensor. Freezer
Sentry does not come with these sensors, but they can be added at any time. A
leak sensor is an especially good idea as you can monitor your refrigerator/
freezer for leaks.
Lastly, you can enable and disable email, text, and the siren feature for any of the
inputs by clicking on the text bubble. Do not forget to click the submit button if you
have made any changes on this screen.
Alarms can be temporarily disabled by pressing the silence button on the Freezer
Sentry. If an alarm cannot be quickly resolved, it will be necessary to disable the
siren checkbox for the given sensor in the portal or application.
