Energy dashboard & long-term statistics

The recorded history is published into Home Assistant’s own long-term statistics, under this integration’s bavariandata: namespace: charging energy (kWh), charging cost and driving distance — one series per vehicle.

Why external statistics#

They’re written as external statistics, so they can cover hours no entity was alive for. That means charging from before you installed this, or from while Home Assistant was down, still lands on the Energy dashboard.

Adding to the Energy dashboard#

Settings → Dashboards → Energy → Individual devices, and add the series (or the Charged Energy (Total) entity).

A mirror, not a second archive#

The statistics mirror the store rather than being a separate archive: each rebuild regenerates the whole series from the records still held, so your retention setting genuinely governs everything kept.

It happens automatically as sessions and trips are recorded. To force a rebuild:

• bavariandata.import_statistics — rebuilds from the store and reports the row counts. Useful after restoring a backup, or to verify the counts.

Turning it off#

Toggle statistics_import off under Configure → Charging costs & history. This also deletes the published series — no stale mirror is left lingering on the Energy dashboard.
