Sensor History overview

The History tab lets you check a sensor’s latest readings, see how measurements change over time, and export historical data.

1. Select Sensors from the navigation menu.
2. Open the sensor you want to review.
3. Select the History tab.

The page has three sections:

• Sensor Summary - the latest reported values.
• Time-Series Chart - measurements plotted over a selected period.
• Historical Data Table - readings organized by time, with a CSV export option.

The top summary panel displays cards for sensor parameters supported by the selected sensor model and model version. Each card shows the parameter name, latest reported value, measurement unit, and any configured Threshold Breach rule values where applicable.

Hover over a parameter card to view the full parameter name, its description, and the Last Activity timestamp associated with the displayed value. Threshold Breach events visually highlight affected values.

The panel refreshes latest values approximately every 30 seconds (±5 seconds). Missing values are shown as -; invalid values use a warning state. Unsupported or unconfigured thresholds are also indicated as unavailable.

1. Click the Settings (gear) icon at the upper-right of the summary cards.
2. In Visibility Preferences, enable the parameters you want to display and disable those you want to hide.
3. Apply your changes.

At least one parameter must remain selected. Your choices are saved for your account and sensor model. Hiding a card does not delete its measurements.

Use the Time-Series Chart to view trends or compare up to two parameters. See Analyzing Sensor Measurements.

Use the Historical Data Table to inspect individual time intervals, view multiple parameters, and download a CSV file. See Viewing and Exporting Historical Data.

Note: The chart and table have separate controls. Changing the date range or parameters in one does not change the other.
