Kiosks running our pre-built image (managed_image=true at pairing) can
have their hostname, timezone, network (DHCP/static + VLAN), and Wi-Fi
configured from the admin UI. Pull-model: server stores desired-state
JSON, kiosk heartbeat returns pending_config when version exceeds
applied_version, kiosk echoes applied_version back. Wi-Fi PSK encrypted
with the cluster key so ciphertext at rest is shipped to the kiosk
without per-kiosk re-encryption.
Server side only — kiosk Rust applier (betterframe-apply-config helper
+ rollback timer) and pair-initiate marker file are next.
ci(pi-gen): use action's image-path output for asset upload
pi-gen writes the .img.xz into pi-gen-action's own working dir, not our
repo deploy/. Glob never matched. Use steps.pigen.outputs.image-path
directly — no glob needed.
Adds aggressive normalisation to tryParsePrivateKey:
- Strip UTF-8 BOM
- Replace smart quotes (" " ' ') with ASCII
- Strip multiple layers of wrapping quotes
- Combine escape-unfold with quote-strip (env vars that quote AND escape)
- Strip whitespace inside base64 candidate before decode
On parse failure, dumps length + head/tail samples + first-byte hex so
the operator can spot exactly what shape the env var arrived in.
Coolify / docker compose env injection routinely strips real newlines or
wraps in quotes, causing createPrivateKey to throw ERR_OSSL_UNSUPPORTED
and crashing the server before it can even start.
tryParsePrivateKey now attempts: literal, \n→LF, CRLF→LF, quote-stripped,
base64-decoded, and single-line PEM re-wrapped to 64-col. On total
failure, logs a clear warning and falls back to on-disk / generated key
instead of crashing.
Kiosk now exposes :18090 with two surfaces:
- GET /local/layout/:id?key=<kiosk_local_key>
Bookmark-friendly layout switch on this kiosk. Auth = kiosk-generated
local key (32 random bytes, hex, stored at <state_dir>/local.key).
- ANY /proxy/* — forwards to BF server with the request's Authorization
header preserved. Lets LAN clients reach a cloud-hosted BF server via
the kiosk's local socket; kiosk adds no auth of its own.
Heartbeat reports {local_key, local_port}; kiosks table grows
local_key/local_port/local_last_ip columns. Admin kiosk edit page now
shows the local URLs as a copy-paste block.
Override port: BF_KIOSK_LOCAL_PORT. Disable: BF_KIOSK_LOCAL_DISABLE=1.
Three related fixes:
1. Idle reverts (and any other kiosk-initiated layout switch) now POST
layout.changed to /api/kiosk/event. Previously the server only emitted
on admin-initiated switches, so Node-RED never saw the idle revert.
2. Server's /api/kiosk/event splays the payload to the top level when
the topic has a dedicated trigger node (layout.changed, kiosk.changed,
kiosk.status, display.power.changed, camera.changed). The trigger
nodes expect flat shapes matching the admin emit; the old wrapped
shape left every field undefined.
3. Auto-provisioning of bf-server-config in Node-RED: extend retry
window to ~5 min, log per attempt, force v2 API + full-deploy header
so credentials inline get accepted, surface response body on failure.
Kiosk heartbeat reports local display positions so the server can sync physical outputs without consuming global display indices.
Migrate displays.index away from global uniqueness because display numbering is only meaningful within a kiosk.
Server mints a dedicated admin API key on first boot (persisted plaintext
encrypted in setup_state.extras) and POSTs a bf-server-config node into
Node-RED's flow graph via /nrdp/flows. Idempotent — skips if any
bf-server-config already exists, so user-owned configs win.
New admin-http config 'selfUrl' (defaults to http://127.0.0.1:18080)
tells Node-RED how to reach the BF server. Docker compose sets it to
http://server:18080 so requests stay inside the compose network.
is_enabled column on displays (default 1). Disabled displays are filtered
from the kiosk bundle so the kiosk never opens a window on them. Admin
edit page exposes a checkbox; list page shows a "disabled" badge.
Trigger nodes now self-contained inputs (inputs:0):
- Each registers POST /api/internal/<topic> on RED.httpNode
- Angie returns 404 for any /api/* not whitelisted (kiosk/pair/admin)
so external requests cannot trigger BF nodes
- Server bridge POSTs direct to nodered container (bypasses Angie)
- nodered-bridge.ts updated to use /api/internal/<topic>
- 6 trigger nodes converted: display-power, layout-changed,
kiosk-changed, camera-changed, status, kiosk-camera-event
- Optional per-node filters (display_id, kiosk_id, camera_id)
- close handler removes only this node's route layer
- bf-status: query kiosk state by ID via /api/admin/kiosks/:id
- bf-trigger-status: dedicated heartbeat-only topic kiosk.status
(skips connect/disconnect noise from kiosk.changed)
- bf-snapshot: GET /admin/entities/:id/snapshot as Buffer for
motion → email/telegram flows
- coordinator-ws now forwards both kiosk.changed (event=heartbeat)
AND kiosk.status on every status message
Action buttons that don't need a redirect now use hx-post:
- Kiosk power (wake/standby), fan (auto/off/50%/full)
- Kiosk switch-layout dropdown
- Kiosk GPIO delete (row swap-out)
- Camera labels add/remove (list re-render)
- Kiosk labels add/remove (list re-render)
- Display attach/detach layout (list re-render)
Server routes return HTML fragments via isHtmxRequest() check,
otherwise still 302 redirect for direct-URL access.
Forms that legitimately redirect (create/edit/delete, auth flows)
stay as standard form posts.
- Dockerfile.server: RUN npm run build during builder stage so the
image ships pre-compiled lib/ + bsb-plugin.json. Runtime image also
installs ffmpeg (for camera snapshot endpoint).
- DisplayEditPage Show buttons + Switch dropdown now use hx-post
with hx-swap=none — no page reload, just fires the command.
Multi-display:
- Bundle ships displays[] each with own layouts + idle/sleep
- Rust kiosk creates one ApplicationWindow per gdk monitor
- Per-display state (layout, idle, sleep) via HashMap
- WARM_CAMERAS pool shared across displays
- Backward-compat top-level display/layouts still emitted
System Health (/admin/health):
- Online status, CPU temp (color-coded), fan RPM/PWM
- Bundle version mismatch detection
- 30s auto-refresh
Camera snapshot/test:
- shared/snapshot.ts: ffmpeg/gst-launch fallback, 5s timeout
- /admin/entities/:id/snapshot returns JPEG
- EntityEditPage shows live preview with Refresh
GPIO (Pi buttons/sensors):
- kiosk_gpio_bindings table + CRUD admin UI
- Bundle ships gpio_bindings[]
- kiosk/src/gpio.rs with gpiod crate, worker thread per pin
- Edge events POST to /api/kiosk/event with source_type=gpio
Layout switch fixes:
- GET aliases added so direct URL hits work
- New /admin/displays/:displayId/layout/:layoutId for multi-display
- DisplayEditPage gets "Switch Layout Now" section
Node-RED embed:
- /admin/nodered renders iframe at /nrdp/
- Sandbox attrs allow scripts/forms/popups
- Sidebar link now opens embedded view
Bind native backend services and Node-RED to loopback so Angie remains the public auth boundary. Keep Docker on an internal compose network and stop kiosk fallback to a layout when display default is none.
Entities:
- New entities table — id, name, type (camera|html|web), camera_id,
html_content, web_url
- Auto-create entity per camera on createCamera
- Layout cells reference entity_id (replaces inline content_type/
camera_id/html_content/web_url)
- Bundle resolves entities back to legacy cell fields for kiosk compat
(Rust kiosk unchanged)
- Full CRUD: /admin/entities, /admin/entities/new, /admin/entities/:id
- Cell editor: single entity dropdown with type badges
ONVIF discovery:
- /admin/cameras/discover — host/port/user/pass form
- Server queries ONVIF device, lists profiles with name/resolution/
encoding/framerate
- "Add" creates camera + main stream from chosen profile
- shared/onvif.ts: minimal SOAP+UsernameToken+PasswordDigest client
(no external dep)
- Camera new form simplified to RTSP-only with discover link
- shared/nodered-bridge.ts: fire-and-forget POST to Node-RED HTTP-in
- api-http: kiosk event endpoint now forwards to Node-RED at /in/<topic>
- Best-effort, never blocks. 3s timeout, warn on failure.
- sec-config: noderedUrl on api-http (defaults to http://127.0.0.1:1880)
Node-RED flows can attach http-in nodes at /in/<topic> to receive
camera motion, GPIO events, etc. Inbound commands (Node-RED → server)
go through the admin API with admin Bearer token (no new endpoints
needed for v0.1).
Rust kiosk:
- web cells now use webkit6 WebView (load_uri)
- html cells use WebView.load_html (full HTML rendering)
- query_displays() reads /sys/class/drm/ for connected HDMI/DP outputs
- Heartbeat reports display geometry every 60s
Server:
- /api/kiosk/heartbeat accepts displays array
- Syncs kiosk-reported displays to display records
- Updates dimensions when changed, creates new displays for new ports
UI improvements:
- Click cell → htmx swaps in edit form inside the cell (no page reload)
- Cancel re-fetches cell in read mode
- Save returns updated cell HTML, htmx swaps it
- Edit form includes Width/Height inputs for col_span/row_span
- Inline +W/-W/+H/-H buttons on each cell for quick resize
- Add (+) and delete (×) buttons also htmx — only the grid swaps
Routes:
- GET /admin/layouts/:id/cells/:cellId — cell fragment (read mode)
- GET /admin/layouts/:id/cells/:cellId/edit — cell fragment (edit mode)
- POST /admin/layouts/:id/cells/:cellId/resize — adjust span by delta
- All cell ops return fragment if hx-request header present, else 302
All mutations trigger notifyKiosks() — kiosks live-update via WS.
- Migrations now run exactly once per DB lifetime, tracked via
SQLite's user_version PRAGMA
- Re-runs become no-ops after schema reaches target version
- v0.2 also made defensive — skips if template_id already dropped
Fixes "no such column: layouts.template_id" on second startup after
v0.5 rebuild dropped the legacy columns.
Server side:
- service-coordinator-ws: full WS implementation using ws package
- Auth via ?token=<kiosk_key> query param
- Coordinator registry for cross-plugin notification
- Admin mutations call notifyKiosks() → server pushes reload-bundle
- 30s ping/pong heartbeat
Kiosk side:
- Rust ws_client with tokio runtime + tokio-tungstenite
- Auto-reconnect with exponential backoff (1s → 60s cap)
- On reload-bundle: re-fetches bundle, re-renders layout
- Pong replies to server pings
Also fix: auto-suffix kiosk name on UNIQUE collision (re-pair with
same hostname no longer fails).
