Dashboard Notify

An AI-generated notification carousel for wall displays. Scheduled notifications, motion detection events, and an idle placeholder rotate through an auto-advancing carousel — each backed by a freshly generated image.

Overview

Wall-mounted displays show a live carousel of notifications, each paired with an AI-generated image. Three content sources feed the carousel:

  1. Scheduled notifications — YAML config defines time-windowed notifications with custom text and a scene hint. When a schedule is active, the app generates an image via the configured AI provider and adds it to the pool.
  2. Detection summary hook — Listens for detection_summary/run_published events from detection_summary_app and injects the detection's generated image as a carousel entry.
  3. Idle placeholder — When no notifications are active, a calming AI-generated image fills the display. It refreshes on a configurable interval.

The card supports swipe gestures, manual pause, and per-notification dismiss.

Image generation

Images are generated using the configured AI provider (OpenAI or Gemini). Each image is built from:

  • The notification text and scene hint
  • A randomly selected style profile (cartoon, watercolor, pixel art, etc.)
  • A randomly selected environment variant (space, underwater, enchanted forest, etc.)

Both layers are applied as secondary appearance/setting modifiers — subject content is always preserved.

Dashboard card

The custom:dashboard-notify-card element provides the carousel UI. It reads from sensor.dashboard_notify_status and sends commands (dismiss, pause, navigate) via script.dashboard_notify_relay.
