Before You Begin

Requirements

• Device must have an Asset Type with defined properties
• Device must have sent at least one uplink message
• Properties appear after the Asset Type is assigned

---

Viewing Current Sensor Values

Step 1: Open Device Details

1. Click the Settings gear icon in the sidebar
2. Select IoT Management from the dropdown
3. Click on the device name

Step 2: View Current Data

In the Data Overview tab, you'll see property cards showing:

Display	Description
Property Name	What's being measured (e.g., Temperature)
Current Value	Latest reading from the device
Unit	Measurement unit (°C, %, kWh, etc.)

---

Viewing Historical Data

Property History Chart

Below the current values, you'll find the Property History section:

1. Select Time Range using the dropdown:

   • Last 24 Hours (default)
   • Last 7 Days
   • This Week / Last Week
   • This Month / Last Month
   • Last Quarter
   • Custom Range (up to 120 days)

2. Filter by Data Quality:

   • All Data
   • Valid Only
   • Invalid Only

3. View the Chart:

   • X-axis: Time
   • Y-axis: Property values
   • Multiple properties shown as separate lines

4. Export Data: Click Export CSV to download

Understanding Sensor Properties

Properties are defined in the Asset Type and map to payload data:

Property	Type	Example Value	Unit
Temperature	Number	24.5	°C
Humidity	Number	65.2	%
Battery	Number	85	%
Door Open	Boolean	true	—
CO2 Level	Number	412	ppm

Missing Properties?

If you don't see expected properties, verify the Asset Type has them defined. Go to Asset Types and check the property configuration.

---

Viewing Uplink Logs

For raw message data:

1. Click the Uplink Logs tab
2. See all messages with:
   • Timestamp
   • Full payload data
   • RSSI and signal data
   • Frame counter

Use this for troubleshooting or verifying data transmission.

Exporting Sensor Data

Export from Chart

1. Open device details
2. Go to Data Overview tab
3. Set your desired time range
4. Click Export CSV

Export Contents

The CSV includes:

• Timestamp
• Property name
• Value
• Unit
• Data quality flag

Real-World Examples

Example 1: Check Temperature Trend

Situation: You need to verify cold storage temperature stayed below 4°C overnight.

Solution:

1. Click the Settings gear → IoT Management
2. Click on the cold storage temperature sensor
3. In Property History, select Last 24 Hours
4. Review the temperature line chart
5. Look for any spikes above 4°C
6. Export CSV if documentation is needed

Result: The chart shows temperature stayed between 2-3°C all night. You export the data for the compliance log.

---

Example 2: Compare Multiple Properties

Situation: You suspect humidity is affecting temperature readings in the server room.

Solution:

1. Open the server room multi-sensor
2. View Property History showing both temperature and humidity
3. Look for correlation:
   • When humidity rises, does temperature follow?
   • Are there patterns at specific times?
4. Select Last 7 Days for trend analysis

Result: You notice humidity spikes every day at 2 PM when cleaning occurs, causing a temporary temperature rise. You adjust cleaning schedule.

---

Example 3: Export Data for ESG Report

Situation: Your sustainability team needs energy consumption data for the quarterly GRI report.

Solution:

1. Go to Settings gear → IoT Management and find the energy meter
2. Open device details
3. Set time range to Last Quarter
4. Filter: Valid Only (exclude any flagged bad data)
5. Export CSV
6. Share with sustainability team

Result: Clean, validated energy data ready for compliance reporting.

---

Example 4: Troubleshoot Missing Data

Situation: A sensor shows current data but no historical chart.

Solution:

1. Check Last Message time — is data coming in?
2. Verify Asset Type has properties defined
3. Check the Uplink Logs tab for raw payloads
4. Confirm payload contains expected property keys
5. If payload structure changed, update the Asset Type codec

Result: You find the vendor updated firmware, changing the payload format. Update the codec to match.

Data Quality Management

Flagging Invalid Data

When sensor readings are incorrect (e.g., sensor malfunction):

1. Open the device
2. Find the suspicious data point
3. Click to flag as Invalid
4. Enter a reason (e.g., "Sensor glitch during maintenance")

Using Quality Filters

• All Data: Shows everything, valid and invalid
• Valid Only: Excludes flagged readings (use for reports)
• Invalid Only: Shows only flagged data (for review)

---

Time Range Options

Range	Use For
Last 24 Hours	Recent activity, troubleshooting
Last 7 Days	Weekly review
This Week	Current week analysis
Last Week	Previous week comparison
This Month	Monthly reporting
Last Month	Previous month comparison
Last Quarter	Quarterly compliance reports
Custom	Specific date ranges (up to 120 days)

---

Data Retention

Plan	Historical Data Retention
Lite	7 days
Basic	30 days
Professional	90 days
Enterprise	365 days

caution

Data beyond your retention period is automatically deleted. Export important data before it expires.
