Charts in the browser are convenient; CSV export is for questions the built-in UI does not answer. Spreadsheet tools let you compute degree-hours, correlate with weather files, and share trimmed datasets with contractors or insurers.

Typical export columns

Exports include timestamps, probe identifiers, Fahrenheit and Celsius values, and humidity where available. Join on time buckets when merging with external weather CSVs. Subscription access is managed through Stripe billing.

Analysis ideas

  1. Weekly minimum temperature by zone for freeze planning.
  2. Door-event detection by pairing sharp drops with your own activity log.
  3. Before/after insulation comparison using the same date range year over year.

Workflow tips

  • Import into LibreOffice Calc or Excel; freeze panes on the timestamp column.
  • Use pivot tables to aggregate by hour of day and find chronic cold windows.
  • Keep raw exports archived: re-derive charts when questions change.
