Smart Buildings Shared-family mapped

TallyBand

Classroom Attendance Band

Privacy-safe headcount band per classroom period (empty / sparse / half / full) for space utilization and safety muster — never identity, never a camera in a classroom.

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 Buildings 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: Privacy-safe headcount band per classroom period (empty / sparse / half / full) for space utilization and safety muster — never identity, never a camera in a classroom.

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

See the environment before installing it.

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 Buildings scene

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

01 The physics

Aggregate multipath perturbation and breathing-band energy scale near-monotonically with occupant count (r=0.9 proven); banded output (not exact count) stays inside the honest accuracy envelope of a 1-2 node room at 20-35 occupants.

02 Shared processing path

Eigen-mode crowd_index + breathing-band energy -> banded quantizer calibrated on 5 known-count sessions -> per-period attendance band with confidence; explicit refusal to output an exact headcount above the validated ceiling.

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

Own-hardware in two classrooms, 4 weeks vs roster ground truth; report band-confusion matrix and the count ceiling at which bands stop separating.

04 Commercial hypothesis

For campus ops: 'Real utilization per period and a live muster check — with nothing in the room that can identify a student.'
