GENERAL SETUP PROCEDURES

It’s important to understand the setup procedure for activating your Next Sensor. If you perform the following steps out of sequence, your sensor may have trouble communicating with the Wi-Fi access point and Monnit software. Please perform the steps below in the order indicated to ensure the best results.

Set up the Monn it Software of choice. (Create an account if this is the first time.)
- iMonnit Premiere, iMonnit Enterprise, iMonnit Express, or Monnit Mine
- https://monnit.blob.core.windows.net/site/documents/software/iMonnit/lM-P-MUG-01.pdf LINK

Add the Next Sensor(s) to iMonnit or other approved software.
- https://support.monnit.com/article/191-how-to-add-devices-in-imonnit LINK
Add batteries, wait about seven seconds, then power on the Next sensor by pressing the power/utility button. The LED will turn green for two seconds indicating that the sensor has just powered on. If you haven’t configured the Wi-Fi settings, the LED will double flash red. If already configured and able to connect to iMonnit, the LED will double flash green.

To provision the Wi-Fi settings for the first time:
- Download and install the Bluetooth provisioning app on your phone. ADD FULL LINKS
- Follow the on-screen prompts to configure Wi-Fi credentials on your device.

Once successfully configured and able to communicate with the server, the sensor will automatically exit Bluetooth mode and attempt to send data immediately.
- If the data transmission is successful, the LED will double-flash greener double-flash for communication failure.If a red flash occurs, short-press the button to try the communication again. If communication fails again, see the troubleshooting section.
Ensure the sensor connects to the configured access point and Monnit Software by checking for new data in the Monnit Software.

Install sensor(s) in the final location.
- Refer to this guide’s Batteries and Installation section for useful general mounting, installation, and placement recommendations.
- Refer to the sensor-specific configuration and installation guide for further installation and setup information. LINKS HERE

Note: Next Sensors send 10 transmissions 30 seconds apart when communicating with iMonnit for the first time after resetting or powering on before engaging the configured interval or Heartbeat.

Diagram point ing t o but t on and LED referred to in instruction above. LED called St at us LED for now. But on called Power /Utility button for now. This diagram may also work well in the ABOUT section. I defer to Marketing on this.

BATTERIES & INSTALLATION

Next Sensors are powered by two removable AA (1.SV) batteries (included).
You can purchase additional sensor batteries from Monnit directly. We encourage customers to recycle all old batteries.

NOTE: Next Sensors retain their configurations in non-volatile memory (without power). When batteries are replaced, the sensors will continue functioning and provide previously configured data.

POWER SENSOR ON/OFF

ON: Wait up to seven seconds after installing batteries then press and release the power button to power the sensor.

OFF: Hold the button down for up to 15 seconds to turn the sensor off. Release the button when the LED goes off.

INSTALLING/REPLACING BATTERIES
To install batteries, open the sensor lid by pinching the sides of the case and pulling away from the base. Then, insert the new AA batteries in the carriage and close the lid by pushing the lid and the case together until the clips snap. If your sensor is attached to any other systems or voltages, we recommend powering off the other system and disconnecting this sensor.

WARNING: ONLY install new batteries from the same manufacturer when replacing batteries in Next Sensors.

Image should be added here to show how the case works

SENSOR PLACEMENT
Place each Next Sensor within 125 feet of its Wi-Fi access point. Sensors should be installed to avoid transmissions through a lot of metal or concrete and repositioned to avoid such obstacles if communication is spotty. A sensor should also be placed at least one foot away from the Wi-Fi access point and other sensors.

Next Sensors should NOT be placed where they can be exposed to volatile or flammable gas. A Next Sensor should be deployed where it will be protected from operating temperatures outside those disclosed in the data sheet. We also recommend that you not place Next Sensors in fridges and freezers. A lead sensor will still allow monitoring of temperatures inside fridges and freezers.

A Power/Utility button is included on Next Sensors for your convenience. If you aren’t using the sensor, turn the sensor off by holding the button until the LED turns off. If the sensor needs to be reset, you can cycle the power by turning it off and waiting 10 seconds before powering it back on.

Next Sensors aren’t designed for wet environments, environments with fluctuating or excessive humidity, or where they’ll be exposed to corrosive or deoxidizing gas or vapor (e.g., chlorine gas, hydrogen sulfide gas, ammonia gas, sulfuric acid gas, nitric oxide gas, etc.). Next Sensors also should not be placed in excessively dusty locations; places with salt water, oils, chemical liquids, or organic solvents; low- or high-pressure environments; areas with powerful vibrations; or in other places where similar hazardous locations exist.

MOUNTING A SENSOR
Next Sensors can be mounted to most surface using screws or double-sided tape (both included).The Next enclosure features keyhole mounting holes molded in to the enclosure back plate and guides for the double-sided tape.
For masonry, use the double-sided tape or use appropriate screw anchors for #7, 7 /16″ (0.4375″) screws. If the screws aren’t available, use two #7 size screws of proper length for your application. If the included double-sided tape is unavailable, use one or more pre-cut, double-sided foam squares of dimensions 1/32″ x 3/4″ x 3/4″, available from ULINE as model number S-11695, or the like.

CLEANING

When needed, clean the sensor with a damp but not dripping wet cloth where it’s installed. Do not use cleaners or chemicals.

Is t his warning correct and

WARNING: In placing the sensor, be aware that it has a mechanical impact rating of IK06, meaning the housing protects the sensor from a mechanical impact of one Joule. This is roughly equivalent to dropping a solid metal sphere weighing 500 grams from 20 centimeters onto the respective housing. Next Sensors aren’t rated for greater mechanical impact based on a documented Risk Analysis performed by Monnit. Therefore, the IK06 rating is justified because the sensors should be:

Installed in locations that unauthorized persons or the general public can’t easily access
Accessed during normal use for occasional operations such as adjustment, programming,or maintenance

We recommend adhering to these stipulations because using the sensors in a manner inconsistent with the above may impair their IK06 protection.

GENERAL AND Wi-Fi SETTINGS CONFIGURATION (iMONNIT)

GENERAL SETTINGS CONFIGURATION
These are configurable settings for almost every Next Sensor.

Heartbeat: How often the sensor transmits data to the server when not in the Aware State.
Aware Heartbeat: How often the sensor transmits data to the sever when in the Aware State.

Server Address: The server the sensor communicates with. If the sensor is unlocked, this setting is editable, If not, this setting isn’t visible.
Server Port: Port used for server communication. If the sensor is unlocked, this is editable, If not, this setting isn’t visible

Wi-Fi SETTINGSCONFIGURATION
These setting configurations control what Wi-Fi access points the sensor can communicate with and how the IP address is assigned.

Sensor IP Address: Determines if the sensor uses DHCP to obtain an IP address.
IP Address: The IP address the sensor will use on the network it joins.
Subnet Mask: A 32-bit number that helps routers direct data packets to the correct place on a network.

Default Gateway: IP address of the devices serving as the gateway to the Internet. Typically, your Wi-Fi-enabled router.
DNS Server: IP address of the device that resolves DNS queries for the network. Often, your Wi-Fi-enabled router.
Primary Wi-Fi Network: The first configurable Wi-Fi network. The sensor will typically try to connect to this network first.

SSID: The text name of your Wi-Fi access point.
Security Type: Open, WPA, WPA2_PSK, WPA_WPA2_PSK, WPA3_PSK, WPA2_WPA3_PSK
- Security Key: The passkey for the access point can be left blank if set to open security.

Secondary/Tertiary Wi-Fi Network: The second and third configurable Wi-Fi networks.

NOTE: For sensor-specific setting configurations refer to the specific sensor’s configuration and installation guide.

OPERATING MODES

STANDARD
The sensor will communicate data to iMonnit using the configured settings in this mode.

BLUETOOTH
In this mode the sensor is disabled (no sensor data will be generated) and Bluetooth is activated. Short button presses only reset the Bluetooth auto exit timeout.

PAIRING: While in the pairing state the LED flashes blue and the sensor is discoverable by the provisioning app.
PAIRED:When paired,the sensor is connected to the provisioning app and Wi-Fi credential scan be configured. If the sensor loses connection with BT on the app device,it will automatically revert to the pairing state.The sensor will automatically exit BT mode after 10 minutes to save power

CRITICALLY LOW BATTERY
When the battery voltage falls below 2.15 volts, the sensor enters a low power data logging-only mode. Wi-Fi and Bluetooth are fully disabled in this mode to save power so provisioning and data transmissions are not allowed. If the sensor had already sent data to the server when the battery level dropped it will continue logging data to flash. Typical green LED flashes for button and power activity are replaced with red LED flashes. If the sensor is powered on with a critically low battery it will not log data since it requires time from the server to generate data. The LED will also flash solid red for 2 second instead of green upon boot or power cycle. To exit this mode the average battery voltage must rise above 2.3 volts.

MONN IT DATA SECURITY

How Monnit Encrypt-RF ™ Works

Your data security is a top priority at Monnit. Next uses a powerful combination of hardware, software, and firmware security to ensure your data is fully secure.

HARDWARE/FIRMWARE SECURITY
Every piece of Next hardware implements read locked flash preventing third parties from downloading any data saved directly on the device. Monn it Next sensors also use secure boot technology that takes it impossible for malicious applications to run on the device.

SENSOR TO SERVER SECURITY
Monnit’s sensor-to-server, secure communication tunnel, Encrypt-RF™, is generated using ECDH-256 (Elliptic Curve Diffie-Hellman) public key exchange to generate a unique symmetric key between each pair of devices. Sensors and gateways use this link-specific key to process packet-level data with hardware-accelerated 128-bit AES encryption, minimizing power consumption to provide better battery life. Monnit proudly offers robust bank-grade security at every level, thanks to this combination.

iMONNIT SECURITY
The iMonnit system is the cloud software and central hub for configuring device settings. All data is secured on dedicated servers operating Microsoft SQL Server. Access is granted through the iMonnit user interface that requires Two-Factor Authentication (2FA) 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 an iMonnit Basic or Premiere user. You can rest assured that your data is safe in iMonnit.
