Telemetry
View sensor data and device variables in the dashboard.
What is Telemetry?
Telemetry is the automatic collection of sensor data from your devices. Your devices push readings at regular intervals, and the dashboard stores and displays this data for real-time monitoring and historical analysis.
Viewing Telemetry
To access telemetry data:
- Go to Monitoring in the sidebar
- Click Telemetry
- Select a device to view its data
- Choose variables to display on the chart
You can also see real-time telemetry in the Variables section of any device's control panel.
The Telemetry Dashboard
The telemetry page provides several views for analyzing your data:
Line Charts
Track values over time. See how temperature, humidity, or other readings change throughout the day.
Current Values
Large displays showing the most recent reading for each variable, updated in real-time.
Min/Max/Average
See statistical summaries for any time period. Identify peaks and trends at a glance.
Multi-Variable View
Compare multiple variables on the same chart. See correlations between sensors.
Time Range Selection
Use the time range picker to view different periods:
Last Hour
Real-time monitoring
Last 24h
Daily patterns
Last 7 Days

Data Retention
How long telemetry data is stored depends on your plan:
| Plan | Retention | Min Resolution |
|---|---|---|
| Free | 7 days | 5 minutes |
| Pro | 30 days | 1 minute |
| Enterprise | 1 year | 1 second |
Exporting Data
Export telemetry data for external analysis:
- Select the device and variables you want
- Choose the time range
- Click Export
- Download as CSV or JSON
Custom Dashboards
Create custom dashboard widgets to visualize telemetry:
- Add gauge widgets for at-a-glance monitoring
- Create line charts for trend analysis
- Build metric cards with current values
- Combine data from multiple devices on one dashboard
