Data Trending

From the Trend tab on any equipment page, you can select up to 5 analog data points to review historical data across a window of up to 31 days. You can also create Saved Views — preset combinations of data points and a time range — so your most-used data is just a click away. Any data you pull up can also be exported to CSV for use in custom reports.

Trend Configuration

Data Points Selector

  • The Data Points dropdown can be used to select up to 5 values. When expanded the field can be used to search by name. Click OK when selections are complete.

Trend Chart

  • Once your data points and time range are set, the trend chart will populate with the available data.

  • Click the legend icons to show or hide individual trend lines — a visual indicator will appear on any hidden trend so you always know what's visible.

  • If data is missing from the specified time window, the trend chart displays labels to help identify the cause of the gap:

    • Gateway Offline — displayed when no data was recorded due to a lost connection to the Generac Link IoT gateway.

    • Equipment Offline — displayed when the gateway was online but the telemetry link to the equipment was lost. This is equivalent to the -99 value displayed elsewhere in the app.

  • The trend chart supports common gestures for navigation: scroll wheel or trackpad pinch to zoom in/out; click+drag or two-finger scroll left/right to pan within the selected time range.

Trend Statistics

  • Below the chart, a statistics summary will show the minimum, maximum, average, and range (max minus min) for the selected period.

  • As you zoom and pan the trend chart, the statistics summary will update to reflect the visible time frame.

Saved Views

  • To create a Saved View, open the Saved Views dropdown and click + ADD SAVED VIEW.

  • Give your view a name, then choose the data points and time range you want to save. Check Make default view if you'd like this view to load automatically every time you open the Trend tab.
