Export (CSV / HTML report)

The Charging and Trips card views each carry CSV and Report buttons that download the current month straight from the browser. Both are backed by the bavariandata.export_history service, so automations can use them too. Nothing is written to disk — the file contents come back as service response data — and it spends no API quota.

CSV#

One row per session or trip:

• Both the battery-side and measured grid energy in separate columns.
• The cost and where it came from.
• For trips, the endpoints as place names.

Headers are always machine-readable English. Opens cleanly in Excel and Numbers.

HTML report#

A self-contained HTML page: month totals, the charging table and the trip journal. Print it (Ctrl/⌘+P → Save as PDF) for a tidy A4 document. The report language follows Home Assistant’s own language, or set it explicitly.

The report is a trip journal and expense helper, not a tax-office-compliant logbook, and says so on the page.
