Working with an Active Monitoring Session

The Kahi Mobile App is your primary tool for installing sensors, viewing live data, and managing the configuration of monitoring jobs while you're on-site. The Kahi Web App is your primary tool for more detailed data analysis, reporting and trend analysis over time. This section covers various tasks and actions you may wish to complete while the Monitoring Session is running.

Viewing Installed Sensors

Within the Kahi Mobile App:

With the appropriate Job Site selected:

• Tap on the “Monitoring” tab at the bottom of the screen to view a summary of the ongoing session
• Tap into any chamber to see:
  • A list of all sensors installed
  • Each sensor’s last recorded readings (Temp, RH, GPP)

Within the Kahi Web App:

With the appropriate Job Site selected:

• Click on the “Monitoring” tab to view a summary of the ongoing session
• Select any Affected chamber to view additional details about that chamber

Syncing Sensor Data

Sensor data is synced in 3 ways:

• Automatically captured by nearby Job Site Gateways and uploaded every 15 minutes.
• Automatically synced to the Kahi Mobile App every 12 seconds while the app is open and nearby transmitting sensors.
• Initiated manually in the Kahi Mobile App at any time.

To manually trigger a sync:

1. Navigate to the desired Monitoring Session in the Kahi Mobile App.
2. Tap “Collect Readings” to collect readings from all installed sensors in all chambers.
3. Walk around the space and bring your phone near the sensor(s) until sync completes.

Monitoring Drying Trends

Monitoring drying trends in the Kahi Web App helps you evaluate how effectively each chamber is progressing over time. You can spot moisture reduction, identify potential issues, and confirm that your drying equipment is performing as expected.

To view drying trends:

1. Open the Monitoring tab for your job site to view a summary of the chamber readings.
2. Click on an Affected Chamber to view a detailed breakdown.
3. Within the Affected Chamber page you can:
   • View a summary graph to visually evaluate daily GPP readings over time
   • View a day by day breakdown of the chamber readings compared to common chamber readings on that day.

If readings plateau or increase unexpectedly, it may signal:

• Equipment failure or inefficiency
• Intrusion of outside air/moisture
• The need to adjust your drying strategy

Chamber Status Indicators

Common and Affected chambers can display one of two different statuses in the Kahi Web App:

• Active: At least one sensor is installed and reporting
• Complete: All sensors have been removed

Note that the Kahi Mobile App does not display completed chambers.

Generating and Downloading Reports

Once your monitoring session is complete—or even during an active job—you can generate a detailed environmental report directly from the Kahi Web App.

To generate a report:

1. Log into the Kahi Web App.
2. Select the job you want to report on.
3. Click into the Monitoring tab.
4. Click the “Generate Report” button.

What’s included in the report:

• Monitoring Session summary including:
  • Name
  • State
  • Start Date
  • End Date
• Location Map
• For each Affected Chamber:
  • Chamber details including:
    • Name
    • Type
    • Associated Monitoring Session
  • Visual graph of drying trends over time
  • Sensor readings for all assets for the entirety of the job compared to the ambient sensor readings for that chamber, as well as all common chambers. This includes the following details:
    • Job Day (D)
    • Unit ID
    • Model Name
    • Temperature (Temp)
    • Relative Humidity (RH)
    • Grains Per Pound (GPP)
    • Grain Depression (GD)

Sharing & Exporting

• Reports are generated in PDF format.
• Once the report is generated it can be found listed in the Reports section of the Kahi Web App
• You can download the report for use in claims documentation, compliance verification, or internal quality checks.

Interpreting Sensor LED Statuses

LED status blink sequences are displayed every 30 seconds when the EnviroSensor is powered on. These blinks will indicate any detected issues with the EnviroSensor or will indicate that the sensor is functioning as expected.

Dealing with Unresponsive or Offline Sensors

Sometimes a sensor may stop updating readings or show as a greyed out entry in the Kahi Mobile App. Here’s how to troubleshoot and restore connectivity:

1. Check the Sensor’s Power
   • Press the A button once.
   • If no LED lights flash, the sensor is powered off
2. Check the Battery Level
   • Hold down the A button while the sensor is powered on.
   • LED indicator will show:
     • Green = Good
     • Yellow = Medium
     • Red = Low
     • 3 Red Blinks = Critically low (<25%)
3. Power Cycle the Sensor
   • Turn it off (press the A button and the power button at the same time), wait 30 seconds, then power it back on.
   • Wait for a blue blink (normal broadcast).
4. Move Closer or Adjust Job Site Gateway Placement
   • Ensure you're within range (~10–30 feet) if using the app to sync.
   • Physical obstacles can interfere with Bluetooth communication. Adjust Job Site Gateway placement to ensure it is within range (ideally in the same room) or all sensors
5. Re-scan the Sensor
   • In the Kahi app, go to the chamber and tap “Collect Readings” or scan the sensor via NFC or QR to force a sync.
6. Still not responding?
   • Replace the sensor with a new one.
   • Use the “Skip Scan” option during removal only if absolutely necessary.

Removing or Replacing a Sensor

To replace a sensor, first install the new one to avoid closing the chamber, then remove the old sensor using one of two methods in the Kahi Mobile App.

From the chamber sensor list if the sensor can easily be identified:

1. Tap the sensor you would like to remove
2. Tap “Remove Sensor”
3. Scan the sensor using NFC or QRCode

From the chamber page if you are unsure which sensor to select:

1. Tap “Scan to configure devices”
2. Scan the sensor using NFC or QRCode
3. Tap “Remove Sensor”
4. Sensor will automatically power down after removal

If you are unavailable to scan the sensor due to loss or failed connectivity, tap “Help” during removal and choose “Skip scan”. This method should be used as a last resort and can result in data not being synced to the Monitoring Session.
