How to Monitor IoT Devices
View real-time connection status, signal quality, and last message times for all your IoT devices from a centralized dashboard.
Quick Summary
Click the Settings gear, select IoT Management to see all connected devices. Green status = online, yellow = stale, red = offline. Click any device for detailed data.
Before You Begin
- You must have IoT devices registered with an Integration Service
- Devices must have sent at least one uplink message
- Your subscription must include IoT device access
Accessing IoT Management
- Click the Settings gear icon in the sidebar
- Select IoT Management from the dropdown
- You'll see a table of all IoT devices in your organization
Understanding the Device List
Table Columns
| Column | Description |
|---|---|
| Name | Device name and location |
| CS | Connection Status (green/yellow/red dot) |
| DevEUI / UUID | Device identifier |
| SQI | Signal Quality Indicator (4 bars) |
| Last Message | Time since last uplink |
| Linked Asset | Count of associated physical assets |
| Asset Type | Device type (e.g., Temperature Sensor) |
| Properties | Sensor properties this device reports |
Connection Status (CS)
| Status | Color | Meaning |
|---|---|---|
| Online | 🟢 Green | Last message received within 5 minutes |
| Stale | 🟡 Yellow | Last message was 5-15 minutes ago |
| Offline | 🔴 Red | No message for more than 15 minutes |
Signal Quality Indicator (SQI)
Based on RSSI (Received Signal Strength Indicator):
| Display | RSSI | Quality | Action Needed |
|---|---|---|---|
| ████ | ≥ -90 dBm | Excellent | None |
| ███░ | -90 to -110 dBm | Good | None |
| ██░░ | -110 to -130 dBm | Fair | Consider gateway placement |
| █░░░ | < -130 dBm | Poor | Move device or add gateway |
Searching and Filtering
Search Devices
Use the search bar to find devices by:
- Device name
- DevEUI / UUID
- Location name
Refresh Data
Click the Refresh button to reload the device list and get the latest status.
Opening Device Details
Click on any device name to open the detailed view with three tabs:
Data Overview Tab
- Current Values: Real-time sensor readings
- Downlink Actions: Send commands to the device
- Property History: Historical data charts
- Associated Assets: Linked physical equipment
Asset Details Tab
- Location and Asset Type
- Serial number, model, manufacturer
- Purchase date and warranty status
- Keep-alive configuration
Uplink Logs Tab
- Full message history
- Raw payload data
- Timestamps and signal data
Real-World Examples
Example 1: Check Server Room Temperature Sensors
Situation: You need to verify all temperature sensors in the data center are online.
Solution:
- Go to IoT Management
- Search for "Server Room" or "Temperature"
- Check the CS column for each sensor
- Green = good, Yellow/Red = investigate
Result: You quickly identify that Sensor #3 is showing yellow (stale). You check and find it needs a battery replacement.
Example 2: Investigate Poor Signal Quality
Situation: A sensor is showing only 1 bar signal quality and intermittent data.
Solution:
- Find the device in IoT Management
- Note the SQI showing 1 bar (poor)
- Click to open device details
- Check Asset Details tab for location
- Visit the physical location and consider:
- Moving the sensor closer to a gateway
- Adding a gateway to improve coverage
- Checking for interference sources
Result: You move the sensor 10 meters closer to the gateway, and signal improves to 3 bars.
Example 3: Find Offline Cold Storage Sensors
Situation: You need to ensure all cold storage sensors are reporting for compliance.
Solution:
- Go to IoT Management
- Search for "Cold Storage"
- Sort by CS (Connection Status)
- Look for any red (offline) indicators
- For offline devices:
- Check Last Message time
- Verify device has power
- Check Integration Service connectivity
Result: You find two sensors offline due to a gateway issue. After restarting the gateway, all sensors come back online.
Example 4: Monitor Multiple Sites
Situation: You manage IoT devices across 5 buildings and need a quick health check.
Solution:
- Go to IoT Management
- Review the full device list (paginate if needed)
- Focus on CS column for any non-green indicators
- Click yellow/red devices to investigate
- Check Last Message for patterns (all offline = gateway issue)
Result: Daily 2-minute check catches issues before they impact operations.
Keep-Alive Configuration
The Keep-Alive setting determines when a device is marked offline:
| Device Report Interval | Recommended Keep-Alive |
|---|---|
| Every 5 minutes | 15-20 minutes |
| Every 15 minutes | 30-45 minutes |
| Every hour | 2-3 hours |
| Every 6 hours | 12 hours |
Set keep-alive to 2-3x your device's reporting interval to avoid false offline alerts.
To change keep-alive:
- Go to Assets > find the device
- Click Edit
- Update the Active Timeout field
- Save
Troubleshooting Offline Devices
| Symptom | Possible Cause | Solution |
|---|---|---|
| Single device offline | Battery dead | Replace battery |
| Single device offline | Device moved | Verify location, check signal |
| Multiple devices offline | Gateway issue | Check gateway status |
| All devices offline | Integration Service down | Check service connectivity |
| Intermittent offline | Poor signal | Improve coverage |
