Temperature Monitoring Overview

The image below shows an example of grocery temperature monitoring.




A) B2 Sensors

B2 Sensors are ultra-small footprint, completely wireless, and NSF-certified sensors for placement in food contact areas.

B) Z Sensors

Z Sensors are typically used in environments that require radio communication through thick metal or concrete. Z Sensors also include a wireless and detachable screen.

C) Handheld Probes

The wireless handheld probe is used to complete digital HACCP SOPs and other repeatable tasks.

D) Gateways

All of our gateway products are plug-and-play. Once installed in an area with good cellular coverage, they will automatically pair with sensors and report to the dashboard.

 

Complexity	Description	Sensor Count
Low	An open-air asset that would typically require 2+ fans/cooling zones within an 8-12+ ft. refrigerated type unit	1
Medium	A closed cavity or open-air asset that would typically require 1-2 fans/cooling zones within a 4-12 ft.  refrigerated type unit	2
High	A closed cavity or open-air asset that typically would require 1 fan/cooling zone within a 4-6 ft. refrigerated type unit	3+

SmartSense Sensor Installation Best Practices 

1. Begin sensor installations using the included installation sheet.
   
   
   • After each sensor is installed, record the device ID and asset name on the installation sheet.
   • Download the installation sheet here.
     
     
2. Make sure to check sensor connectivity when you are done.
   
   
3. Please consider the following information to ensure a successful installation:
   
   
   • B2 Sensors should be installed one per case or one per fan depending on your preference.
   • B2 Sensors and Z Sensors should always be attached to a secure and permanent surface.
     
     
4. This is applicable in walk-in units where you should never install it on a moveable rack or hanging above the door.
   
   
   • Any B2 Sensor in service cases should use a zip tie near the product level.
   • B2 Sensors should be installed central to the case in order to accurately measure the temperature of the whole case (i.e. in the warmest part of the case where food is placed).
   • In open cases with a load limit (bunkers, etc.), make sure the B2 Sensor is located below the load limit line and the product is not stacked too high as this can negatively impact the B2 Sensor signal.

Sensor Count Per Case or Coil

1. In this example, you can see the case break circled.
   
   
   • Cases should have one B2 Sensor per case.
   • B2 Sensors should be installed central to the case (indicated by the red line).
     
     
     
     
2. In this example, a 3-door freezer is shown, but this is one case.
   
   
   • Cases should have one B2 Sensor per case or coil.
   • B2 Sensors should be installed central to the case or coil (indicated by the red line).
     
     
     
     
3. In this example, a portable horizontal display case is displayed:
   
   
   • The case break is on the left and circled in green.
   • Cases should have one sensor per case or coil.
   • The sensor should be installed beneath the wire rack with a zip tie and p-clamp.
   • The sensor should be central to the case at the front near the divider to the air return

Incorrect Installation Examples

1. These B Sensors are installed incorrectly on the honeycomb of a case.
   
   
   • This is the coldest part of the case.
   • The B Sensor should be installed behind it to properly monitor case temperature.
     
     
     
     
2. This B Sensor is incorrectly installed in a deli case.
   
   
   • The B Sensor should be low and close to the product but is installed too high in a case.
   • Installing properly helps to avoid warm air pockets.

BZ Gateway Installation

1. Remove the BZ Gateway from its packaging.
2. Plug the power adapter into the BZ Gateway.
   
   
   
   
3. Plug the BZ Gateway into a designated outlet to charge.
   
   
   
   

   Note: Your BZ Gateway may need to charge for 30 minutes before moving on to step 4.

    

4. Use the signal finder mode on the BZ Gateway to determine an install location with the best cellular signal strength. To enter signal finder mode, hold the power button for more than 2 seconds but less than 5 seconds. A white LED will flash repeatedly to indicate you are in signal finder mode.
   
   
5. To achieve the best connectivity, move the BZ Gateway around the install location until the white LED begins to quickly blink (a blinking red LED indicates a poor cellular signal). Maximum signal strength is represented with a white LED flash every 200ms (the faster the white LED blinks indicates a stronger cellular signal).
   
   
6. Once a good location has been found, quickly press and release the power button to exit signal finder mode.
   
   
7. Attach the provided velcro strips to all four corners on the back of the BZ Gateway.
   
   
   • If installing on metal, concrete walls, or any porous surface that could retain moisture, install the BZ Gateway using the bracket and mounting screws (SKU: TM-GW-VZ-VZW-C, available upon request).
   • Instructions for the BZ Gateway mounting bracket are available below.
     
     
8. Install the BZ Gateway onto a clean wall surface, six feet off the ground, pressing the device firmly against the wall to ensure the velcro fully adheres.
   
   
   
   
9. Once the BZ Gateway is installed, use wire mounts and zip ties to neatly manage the wiring and prevent snagging or damage to the BZ Gateway.

10. Reference the included LED status guide below to confirm the BZ Gateway is communicating.

B2 Sensor Installation

Your SmartSense B2 Sensor arrives powered off.

1. To turn your B2 Sensor on, hold the button for approximately 3 seconds until the green LED begins to blink and immediately release it.
   
   
2. The green LED will remain on for 5 seconds to indicate that it is powered on and broadcasting.
   
   
3. Under normal operation, these are the only times the LED will illuminate.
   
   
4. Once your B2 Sensor is powered on, it cannot be turned off.
   
   
5. Select a location that is the warmest location in your cooler, often near the top and close to the door.
   
   
6. Use the included zip tie to mount the B2 Sensor. The zip tie should be threaded through the mounting loop at the top of the sensor and attached securely to a mounting point so that the sensor is hanging vertically and facing toward the door of your case.
   
   
7. If a suitable mounting point does not exist, use a zip tie anchor by removing the cover of the double stick tape and adhering the anchor to your preferred location. Attach the B2 Sensor to the anchor.
   
   

Note: All of the instructions below for B Sensor installation apply to the B2 Sensor as well.

Troubleshooting Tips

If your SmartSense Gateway is not reporting, please confirm the following:

1. Confirm the proper LED light sequence based on gateway type.
   
   
2. The gateway's power cable is not cut or damaged (if so, you will need to purchase a replacement).
   
   
3. The gateway's power cable is plugged in and the power source has not been compromised.
   
   
4. The gateway is mounted securely and high up on the wall in an upright position. If the gateway is located behind connectivity-blocking objects (metal walls or other units), this can affect connectivity.

If your SmartSense Sensors are not reporting properly, please confirm the following:

1. All gateways are powered on and reporting properly. Please ensure this before troubleshooting sensors.
   
   
2. Confirm the sensor type.
   
   
3. If you are troubleshooting B Sensors, confirm that the sensor is located in a clear line of sight to a gateway - ensure the gateway is not installed behind commonly closed doors, walls, piping, etc. B Sensors will report at all times and do not have an on/off switch. You can remove the B Sensor from the unit and place it near the gateway to confirm it is still reporting properly. If the B Sensor still does not report, please contact Smart Support.
   
   
4. If you are troubleshooting Z Sensors, confirm that the Z Sensor is powered on by pressing the power button on the front face of the sensor.
