Large Range Detail
Advanced History can adjust chart grouping automatically for long date ranges. This keeps month- and year-scale charts readable and avoids unnecessary browser rendering work.
The feature is enabled by default and starts when the selected period reaches the configured threshold. The default threshold is 31 days.
When a range reaches the threshold, Advanced History starts in Automatic detail:
- Statistics Graph Chart Card chooses an appropriate interval for the selected range.
- The chart's Group By picker remains hidden unless
show_group_by_picker: trueis explicitly enabled in Card Defaults. - An information banner shows that automatic grouping is active.
This is the recommended mode for normal use.
Select the close button to dismiss the information banner without changing the active detail mode. The dismissal applies only to the current selected range. Selecting a different qualifying range shows the banner again.
Select Show fine detail in the information banner when you need a more detailed view. Advanced History then uses a finer fixed grouping suitable for the size of the selected range and shows the Group By picker so it can be adjusted further.
Fine detail may take longer to process and render, especially with many entities or comparison enabled. A warning banner remains visible while it is active.
Once selected, Fine detail remains active while you change or navigate date ranges. Select Use automatic detail to return to automatic grouping. Clearing all chart selections also resets the mode to Automatic detail.
For ranges shorter than the configured threshold, the detail banner is not shown and the normal Card Defaults apply.
With the default 31-day threshold, complete calendar months qualify even when they contain only 28, 29 or 30 days.
Open Settings → Devices & services → Advanced History, then select the cog for the Advanced History service.
| Setting | Description |
|---|---|
| Automatic detail for large date ranges | Enables the Automatic/Fine detail controls for long ranges. Disable it to leave grouping entirely to Card Defaults and the chart editor. |
| Automatic detail threshold (days) | The minimum selected range that activates the detail controls. The default is 31 days; accepted values are 7–3650 days. |
Automatic and Fine detail temporarily supply the grouping options required for the active mode. Other options continue to come from Card Defaults and the current chart configuration.
In Automatic detail, an explicit show_group_by_picker: true in Card Defaults keeps the picker visible. Fine detail always shows it so the active grouping can be inspected or changed.
The active mode and grouping are included in the privacy-safe Diagnostics report.
