Insights & Trend Indicators

When your device has telemetry data, the Insights panel appears on the device detail page. It shows a summary card for each data field with trend arrows, value ranges, and anomaly flags.

Trend Arrows

Section titled “Trend Arrows”

The trend arrow compares the latest value to the average of all values in the selected time range. The comparison is a percentage difference:

percentage difference = ((latest - average) / |average|) x 100
ArrowLabelConditionMeaning
↑RisingMore than 10% above averageLatest reading is significantly higher than normal
↗Trending up2% to 10% above averageLatest reading is moderately above normal
→StableWithin 2% of averageLatest reading is close to the average
↘Trending down2% to 10% below averageLatest reading is moderately below normal
↓FallingMore than 10% below averageLatest reading is significantly lower than normal

Example

Section titled “Example”

If your temperature readings average 25.0 C and the latest reading is 28.5 C:

percentage difference = ((28.5 - 25.0) / 25.0) x 100 = 14%

Since 14% is above the 10% threshold, the trend shows ↑ rising.

Value Labels (L, ~, H)

Section titled “Value Labels (L, ~, H)”

Below the latest value, three reference points are displayed:

LabelMeaningCalculation
LLowThe minimum value in the time range
~AverageThe arithmetic mean of all values: sum of values / count
HHighThe maximum value in the time range

These give you a quick sense of where the latest reading sits relative to the full range. If the latest value is close to H, the sensor is near its peak for the period. If close to L, it is near its lowest.

Anomaly Detection

Section titled “Anomaly Detection”

An amber dot (●) appears next to a field name when the latest reading is flagged as an anomaly. This means the latest value is unusually far from the average compared to the normal spread of your data.

The calculation uses the standard deviation (a measure of how spread out your values are):

anomaly = |latest - average| > 2 x standard deviation

In simpler terms: if the latest reading is more than 2 standard deviations away from the mean, it is flagged. This threshold catches roughly the top 5% most unusual readings.

When anomaly detection does not apply

Section titled “When anomaly detection does not apply”
  • If you have fewer than 2 data points (not enough data to calculate spread)
  • If all values are identical (standard deviation is zero, no meaningful deviation)

Expanded Details

Section titled “Expanded Details”

Click any insight card to reveal additional statistics:

MetricDescription
MedianThe middle value when all readings are sorted. Less sensitive to outliers than the average.
Std DevStandard deviation, a measure of how spread out the values are. Higher means more variation.
DeltaThe difference between the latest and the oldest reading in the range (latest minus first). A positive delta means the value has increased over time.
RateThe rate of change per hour: delta divided by the time span in hours. Shows how fast a value is changing.

Time Range

Section titled “Time Range”

All statistics are calculated from the data in your currently selected time range (1 hour, 24 hours, 7 days, or 30 days). Changing the time range recalculates all values.

Field Groups

Section titled “Field Groups”

If your device has field groups configured, you can switch between groups using the tabs above the insights. The “All” tab shows every field.
