A structured record is the foundation, not the twin

A home record describes what has been entered or supported by evidence: rooms, equipment, documents, service events, and utility bills. It can remain useful even when it is incomplete, but it does not automatically model how the home behaves.

A calibrated digital twin can compare observations with expected behavior for that specific home, retain model assumptions and uncertainty, and update when new evidence or outcomes arrive. DwellMetry keeps this advanced analysis separate from ordinary home records. It appears only for eligible homes with supported measurements, sufficient history, required permission, and current validation; it is not a confirmed diagnosis or complete continuously calibrated model of the home.

Keep different kinds of conclusions separate

A device state such as an HVAC system running is not an anomaly. An unusual runtime pattern is not a diagnosis. A possible cause is not a confirmed professional finding. Keeping these distinctions visible protects homeowners from fluent but unsupported certainty.

  • Observation: something directly reported or recorded.
  • Estimate: a model-derived value with assumptions.
  • Hypothesis: one possible explanation among alternatives.
  • Professional finding: a dated finding from an appropriate qualified source.

What future calibration requires

A responsible model needs enough qualified history, weather and context, declared units, data-quality checks, a reproducible model version, and tests showing when it should abstain. A phone image or three-dimensional shape alone cannot reveal hidden insulation, duct leakage, refrigerant condition, wiring condition, internal pipe condition, or structural integrity.
