OpenEnvelope

OpenEnvelope: Window/Door State & Energy-Bleed Alarm

Knows which windows and doors are open — and when you're heating the parking lot.

Readiness Needs edge adapter

The evidence is proven or strong, but this capability still needs a capability-specific ESP32 or Rust runtime adapter.

Evidence Strong theory Supported hypothesis

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

Runtime family Not mapped

No browser runtime is assigned to this capability yet.

Why live sensing is unavailable

No capability-specific offline runtime is mapped yet. Keep the feature visible, explain the required edge adapter, and never fabricate a live result.

Intended capability

Validate this target only after a capability-specific adapter and ground-truth study exist: Detects open windows, propped fire doors and unsealed dock doors — and cross-references HVAC runtime to flag 'heating the parking lot' energy bleed and security exposure after hours.

This describes the intended outcome. Readiness is needs edge adapter, 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

An open aperture radically rewires multipath: glass (eps_r~6, partially reflective) vs open air removes a reflection path and opens a low-loss transmission corridor, shifting specific CIR tap delays/amplitudes in a binary, repeatable way; a swinging door also gives a transient Doppler burst that timestamps the event.

02 Shared processing path

Doppler transient (event trigger) -> CIR sparse-recovery tap-state classification against learned open/closed constellations (axis discovery: teach by cycling each window/door once during setup) -> MVE anomaly for 'open + HVAC on + unoccupied' composite alerts.

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: cycle windows/doors in an ESP32-meshed office, measure per-aperture classification accuracy and hold-time reliability; ESP32-wall for aperture-vs-wall propagation contrast.

04 Commercial hypothesis

For the building operations / sustainability manager: 'Every window and door reports its own state through the WiFi — stop conditioning outdoor air and know which fire door is propped at 2am.'
