Hospitality & Retail Shared-family mapped

RoomTruth

GhostRoom — hotel occupancy truth engine

Knows which hotel rooms are truly empty — from the corridor, through the wall.

Readiness Shared-family mapped

Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.

Evidence Supported hypothesis

Published physics or adjacent results support the hypothesis; capability-specific product and site validation are still required.

Runtime family Occupancy estimate

Coarse occupancy estimate from calibrated multi-link field activity.

When no ESP32 is connected

No compatible ESP32 stream is connected. Use the bundled Hospitality recording; it demonstrates the shared Occupancy estimate runtime, not independent proof of this capability.

Intended capability

Pilot this intended outcome through the shared Occupancy estimate family, then validate it against site-specific ground truth: Detects rooms occupied after checkout, unregistered extra guests, and 'stayover vs vacant' truth for housekeeping routing — through the wall from the corridor, no in-room hardware visible.

This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

Solution blueprint

This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording

A related Hospitality scene

This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.

01 The physics

Presence produces breathing-band CSI modulation (0.1-0.5Hz) and motion Doppler that penetrates a single drywall partition; occupant count changes aggregate multipath variance. Through-wall LOS/NLOS discrimination is already demonstrated (AUC 0.69) and improves with mesh diversity.

02 Shared processing path

Corridor ESP32 mesh -> breathing-band Doppler + presence detector (class A) -> occupancy-count regressor per room compartment -> z-score cross-room transfer so one calibration generalizes across identical room types.

This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.

03 Validation plan

ESP32-wall dataset for through-wall presence; own pilot on one hotel floor comparing against PMS checkout records and housekeeping logs.

04 Commercial hypothesis

Housekeeping router + revenue-leak detector (unregistered guests, smoking-room parties) for the hotel operations director — pays for itself in cleaned-in-sequence labor savings.
