From 8314a61815a9d650eb8f7345168bd467f77379e5 Mon Sep 17 00:00:00 2001 From: "Aaron D. Lee" Date: Fri, 3 Apr 2026 00:06:45 -0400 Subject: [PATCH] Add presence detection, person/vehicle AI detection, health monitoring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Task 1 — Presence: ping family phones, derive household state (EMPTY/KIDS_HOME/ADULTS_HOME/ALL_HOME), configurable departure delay, per-member roles, auto-arm actions via MQTT. Task 2 — Detection: MobileNet-SSD v2 via OpenCV DNN for person/vehicle classification. Vehicle color/size fingerprinting for known car matching. Zone-based filtering per camera. Model download script. Task 3 — Health: periodic disk/MQTT/subsystem checks, auto-prune oldest non-starred recordings on disk pressure, daily digest builder. 126 tests passing.
