Cloudflare (fronting git.thumeit.com) started rejecting image pushes
with 413 Payload Too Large once whiteboard mode's Node runtime + native
resvg bindings made the image significantly bigger than before. Switched
the build/push target to a LAN-local registry (10.0.0.246:3000) that has
nothing in front of it to hit that limit, and updated
docker-compose.yml.example to match.
New Gitea Actions workflow builds both board variants and publishes
them as release assets whenever firmware/version.txt is bumped. The
server can now poll that repo's releases (next to the existing manual
upload) and either surface an "Update frame" button or, with
"Automatically apply updates" checked, stage the new build itself --
the frame still only updates on its own next wake either way.
Replaces the ad-hoc inline styling with a shared base template driven by
CSS custom properties (light/dark palettes), a card-based two-column
layout, and a persistent dark-mode toggle. Also moves quiet-hours'
timezone from the container's TZ env var into a proper web UI setting
(zoneinfo-backed), so it no longer needs a docker-compose.yml edit and
restart to change.
Purely a server-side decision: GET /frame/config hands back a longer
refresh_interval_s while quiet hours are in effect (exactly the seconds
until they end), and clamps the normal interval so the device's next
wake lands at the boundary instead of wandering into the window, when
outside it but approaching. A device already mid-sleep when quiet hours
begin can still land one wake inside the window -- unavoidable without
touching the firmware, since it has no wall-clock awareness -- but from
that wake on it sleeps straight through to the end.
Window is "HH:MM"-"HH:MM", wrap-past-midnight aware (e.g. 22:00-07:00),
in the server's local timezone -- added tzdata to the Dockerfile since
python:3.12-slim doesn't include it and TZ would otherwise silently
resolve to nothing and fall back to UTC.
Also fixed the "overdue" device-status check to account for quiet hours:
without this it would falsely flag a device sleeping through a long
quiet window as unreachable.
firmware/README.md's HTTP vs HTTPS section still described the
public-CA-bundle trust approach that was tried and abandoned in favor
of pinning one specific certificate -- rewritten to match what's
actually there. docs/architecture.md was missing the back-photo button
entirely (sequence diagram and boot-flow bullets only covered next) and
still said the system talks "over plain HTTP" despite HTTPS support.
docker-compose.yml.example's MANAGEMENT_TOKEN comment understated its
scope (said "the web UI", omitting that every /frame/* endpoint is
gated too).
ESP32 side can now reach the tools server over HTTPS: the Tools Server
field accepts an https:// address for a TLS-terminating reverse proxy
in front of the server (which still only ever speaks plain HTTP
itself), trusting Cloudflare's Origin CA root (embedded at build time)
since that's the common way to get a real cert on a private origin.
Every URL the device builds -- image fetch, config check, manage-menu
data, the QR codes' own links -- goes through one build_url() helper
that picks the scheme from what's configured.
Also adds an optional MANAGEMENT_TOKEN (docker-compose.yml) that gates
the web UI (/, /api/*) behind a shared secret -- unset by default, so
existing trusted-LAN deployments are unaffected. The same token is
entered once during the ESP32's captive-portal setup and gets baked
into the manage-menu's QR code (?token=...), so scanning it just works;
visiting the page without a valid token shows a plain entry prompt
instead of the config UI, and a valid query-param hit sets a cookie so
the page's own fetch()/<img> calls stay authorized for the rest of the
visit. Device-facing /frame/* endpoints are unaffected -- a separate,
already-documented trust boundary.
docker-compose.yml is tracked in a repo meant for publishing, so it can't
hold a real API key. Renamed it to docker-compose.yml.example (placeholder
values, safe to commit) and gitignored the real docker-compose.yml --
deploying is now "cp the example, fill in real values, docker compose up",
no .env file needed.
config.load() now reads IMMICH_URL/IMMICH_API_KEY from the environment
and applies them on top of whatever's in config.json, so setting them in
the compose file's environment: block takes effect without ever touching
the web UI. Env vars always win over the UI-saved values when both are
present -- verified they survive a save() with different UI-entered
values still in place.
