Kazzak × the wall

one tap wakes the wall & unlocks audio — then “Welcome home” plays itself

Kazzak × the wall — one nervous system

Everything hard about the dashboard was the data layer — HomeSource, the HA adapter, the mode engine. None of it knows what a screen looks like, so the CrowPanel becomes a third subscriber that also has ears (mic), a mouth (2×3W speakers), and fingers (touch). Below: the live wiring, with eight walkthroughs that animate real flows — pulses ride the wires, the screens react, Kazzak speaks.

An interactive prototype: a custom wall display, a voice assistant, and a live community data layer that all ride one shared data spine. Tap any walkthrough to watch a real flow light up the wiring — the screens react, the assistant speaks. — redding.digital

What transfers from dashboard-spa

Moves as-is — the hard work

HomeSource.ts — the interface itself
haAdapter.ts — HA WS + REST, already written
mockAdapter.ts + fixtures — offline dev stays free
contextEngine.ts — 8 modes, scene weights, brightness
SimContext — becomes the override debugger on every screen

Adapts — layout, not logic

scenes.tsx · Stage/Spine/Upcoming — re-laid for 1024×600 landscape
Type scale — read at 60 cm, not across the room
brightnessFor() — counter device dims differently at night

New on the panel

Kazzak presence — orb states wired to voice_assistant events
Touch affordances — pills + callService() (the wall never had targets)
TTS-sync mouth — speak on NS4168, animate on glass
Hero theming — subscribe hero_ai_image_landscape (already populated by Apply); one scrim keeps the UI legible over any style
Pixels path — render-bridge or LVGL, the one open decision ↓

The one open decision — how pixels reach a microcontroller

Render bridge try first

The P4 runs no browser. A headless renderer (home server) paints a /crowpanel route of the same SPA → frames stream to the panel via ESPHome; touches come back as coordinates (the fintros remote_webview pattern).

Native LVGL (ESPHome)

UI drawn on-device in ESPHome’s LVGL: instant touch, buttery animation, zero extra services — but a second UI codebase, and the React work doesn’t carry over.

Likely landing spot — hybrid: LVGL owns the orb + voice states (they’re ESPHome-local events anyway, and they need the frame rate); the render bridge owns the info cards (where the SPA reuse pays). Decide after the P4 voice pipeline is proven on the bench.

✓ P4 PDM mic — fixed in ESPHome 2026.4 ? micro_wake_word on P4 — unverified → use openWakeWord add-on ✗ mipi_csi camera — not shipped yet (panel’s own cam parked) ? full pipeline under display load — unproven combo

A working prototype of the home dashboard’s “one data layer, many screens” architecture — Home Assistant as the brain, a hand-built SPA as the face, and a small voice satellite for ears and a mouth. Hero artwork comes from the project’s own AI image pipeline. — redding.digital
