New third mode alongside photos/calendar: fetches a .whiteboard file
over plain WebDAV (Basic auth -- generic, not Nextcloud-specific) and
renders it via a small Node.js sidecar using Excalidraw's own real
export code (@excalidraw/utils + @resvg/resvg-js, no headless browser),
since a .whiteboard file turns out to be Excalidraw scene JSON, not an
image. The sidecar runs as a second process inside this same container
(Dockerfile installs Node, start.sh backgrounds it before exec'ing
uvicorn) rather than a separate docker-compose service -- lightweight,
stateless, reachable only at 127.0.0.1 from the Python process, nothing
worth independently scaling.
The rendered PNG is treated exactly like a photo from there on --
composed/quantized through the existing image_pipeline (letterboxed,
never cropped) rather than a second parallel rendering pipeline.
WebDAV credentials support the common "it's actually the same Nextcloud
account as my CalDAV" case (an explicit opt-in checkbox, not silently
inferred) while still working with any WebDAV server generically.
Frame-level source (URL + owning account) follows the same owner-
controls-their-own-data permission split as calendar sources and the
week view's task list: only the account owner can point a frame at it,
anyone linked can clear it.
Honest limitation: this environment has no Node.js/npm, so
render-service/ is written carefully against each library's documented
API (verified via the npm registry, including transitive dependency
licenses after the CalDAV/AGPL surprise earlier this session) but has
never actually been executed. First real docker build is the first
true test -- see render-service/README.md.
calendar_week_start's fixed-weekday anchor ("start on the most recent
Monday") stops making sense once the view isn't a literal calendar
week, so a non-7-day week view now starts calendar_week_start_offset
days from today instead (0 = starts today, negative/positive = past/
future) -- calendar_week_start still governs at the default 7 days,
unchanged.
Also hides the Calendar tab's week-only fields (days to show, layout,
start offset) unless View is actually set to Week, and further hides
the new start-offset field specifically when Days to show is 7 (where
it has no effect). "Week starts on" stays visible for Month too, since
it actually still applies there.
- Day count (2-10, was fixed at 7) -- 5 days trims the weekend clutter
without losing the grid format.
- Layout choice: days side by side (original behavior) or stacked
vertically as full agenda-style sections (reuses _draw_agenda_day,
same approach _build_today_tomorrow already used for a fixed 2 days).
- Optional task list (CalDAV VTODO collections only -- a plain ICS
subscription doesn't meaningfully have one) that takes the space of
one day slot instead of adding an extra one. Same owner-controls-
their-own-data permission split as calendar sources: only the
calendar's owner can point a frame's task list at it, but anyone
linked to the frame can clear it.
Browse-offset paging now moves by N days (was hardcoded to weeks),
identical to the old behavior when days=7. Changing the day count
resets the browse offset, same reasoning as changing views already did.
Each linked person can pin one of the panel's four non-black/white
colors (Yellow/Red/Blue/Green) to their own calendar instead of relying
on calendar_render.py's old auto-cycle-by-owner-name order -- owner-only,
like adding a calendar in the first place. Colors resolve against
whichever palette a frame actually renders with (including a custom
Advanced configuration override), so a pinned "Blue" stays this frame's
actual blue. Event color bars/dots are also bigger and rounded now
across agenda/week/month views, easier to tell apart at a glance.
Weather: multiple cities per frame, geocoded via Open-Meteo (no API
key), shown above the event list on agenda/today & tomorrow/week views
-- never month, no room for it there. Hand-drawn sun/cloud/rain/snow/
thunderstorm icons (no new font/icon asset, same primitives-only
approach the rest of calendar_render.py already uses). City geocoding
handles "City, State" qualifiers Open-Meteo's own search doesn't
(disambiguates same-named cities, e.g. the three "Portland"s).
CalDAV fix: events were never showing despite calendars discovering
fine, because fetch_calendar_events relied on the calendar-query
REPORT's server-side time-range filter, which real servers implement
inconsistently (confirmed against a real server, not just guessed --
reproduced locally with Radicale). Switched to fetching every event
unfiltered and doing all date-window filtering/expansion client-side,
same approach already used for plain ICS feeds.
Calendar rule/grid lines were light gray, which dithers away to
near-invisible on the 6-color e-ink palette -- now black.
CalDAV accounts (Nextcloud, Fastmail, iCloud, ...) can now be linked
alongside the existing single ICS subscription, since one account can
expose several calendars. A frame's Calendar tab now lists calendars
per person rather than one opt-in per person: your own row shows every
calendar you have available with a full add/remove toggle, while other
linked users' rows show only calendars they've included, toggleable
off (mute) but not on -- only a calendar's owner can add it to a
shared frame. FrameCalendar replaces the old single-boolean
UserFrame.calendar_included; existing opt-ins are migrated forward.
Responds to post-launch feedback on calendar mode: configurable
week-start day for week/month views, crisper non-antialiased text
(threshold-masked instead of drawn straight, so Floyd-Steinberg
dithering doesn't speckle glyph edges), a color-coded/proportionally
filled battery icon on the manage overlay, word-wrapped placeholder
text so "Calendar isn't set up yet" no longer clips in portrait, photo
inlay support extended from agenda-only to every view, and a fix so
manage-overlay face labels reposition correctly when a photo inlay is
active (they previously assumed the photo filled the whole canvas).
Also adds a fourth calendar view, "Today & Tomorrow" -- a two-day
agenda that reuses the same per-day row-layout helper the single-day
agenda view already has.
New columns, all ADD COLUMN with inert defaults -- no existing frame's
behavior changes until mode is explicitly switched to "calendar":
- users.calendar_ics_url: one personal iCal/CalDAV subscription per
user, same shape as the existing per-user immich_url/immich_api_key.
- user_frames.calendar_included: explicit per-(user,frame) opt-in,
default off. Being linked to a frame does not by itself contribute
your calendar to it -- each person's calendar is their own data to
share, not something a frame's controller decides on their behalf.
- frames.calendar_view/calendar_photo_inlay/calendar_browse_offset:
per-frame display settings and NEXT/BACK navigation state.
- frames.calendar_checked_at/calendar_cached_events/calendar_fetch_summary:
the throttled merge-fetch cache, same shape as the existing
firmware_update_checked_at/firmware_gitea_latest_version pattern.
_migration_1() is Base.metadata.create_all() -- it already builds
today's full schema straight from models.py. Every migration after it
is an incremental ALTER/UPDATE meant to bring an *existing* install
forward from an older version; replaying them against a brand-new
database collided with columns create_all had already added ("duplicate
column name"), crashing on first boot.
Found while testing the device-status-bar change against a scratch DB.
Every real deployment has been migrating forward incrementally since
before this bug existed, so it never showed up in practice -- but any
brand-new install would have hit it. Fresh databases now jump straight
to the latest schema_version after create_all; existing databases keep
applying whichever migrations are still pending, same as before.
Advanced configuration gains three sliders (PIL ImageEnhance factors
for color/contrast, 0-2, 1=unchanged; a 0-1 dithering strength) applied
to every photo this frame renders. Confirmed the parameter conventions
against a similar project (jwchen119/EPF: ImageEnhance.Color/Contrast,
1.0 baseline) before implementing; dithering strength isn't natively
exposed by PIL's quantize(), so it's implemented by blending the source
toward its own flat/undithered quantization before running Floyd-
Steinberg on the blend -- at 0 there's no quantization error left to
diffuse (exactly the flat result), at 1 it's the original unmodified
behavior, with a smooth continuum between rather than dithering being
an on/off toggle.
image_pipeline.py split into composition (_compose), enhancement
(_enhance), quantization (_quantize), and transpose+pack stages so
render_frame (device bytes) and the new render_preview_png (a normal
viewable PNG, upright logical orientation) share the same pipeline
instead of duplicating it. Named-face overlay label math (face_labels.py)
was already routed through the shared _placement_transform, so it
needed no changes for the new params.
Also added the requested before/after comparison: the Configuration
tab's new Preview card shows the current photo's untouched Immich
preview next to that same photo run through the frame's actual saved
rendering pipeline (two new GET endpoints, /preview/original and
/preview/rendered) -- immediate visual feedback for tuning the palette
and these new sliders. "Refresh preview" re-fetches after saving.
Schema migration v6 adds color_boost/contrast_boost/dither_strength,
defaulting to 1.0/1.0/1.0 -- reproduces the exact previous rendering
until a frame's Configuration tab changes one.
Verified against the live-shaped test database: the migration, sliders
persisting and clamping out-of-range input, both preview endpoints
(real JPEG passthrough / real PNG at correct logical size+orientation),
confirmed dither_strength=0 actually changes the rendered bytes vs.
default, and the standing legacy-device curl suite.
Replaces the smart_crop_faces boolean with a 4-way display_mode select
on each frame's Configuration tab (image_pipeline.DISPLAY_MODES):
- Crop to fill / Crop to faces: the previous False/True behavior,
unchanged (center-crop trimming excess, optionally shifted to keep
faces on screen).
- Stretch to fill (new): fills the panel exactly, aspect ratio not
preserved -- a plain resize, no crop.
- Shrink to fit (new): the whole photo visible, letterboxed with white
where it doesn't fill the panel.
Named-face overlay label positioning (face_labels.py, the manage menu's
"who's in this photo") now goes through a shared _placement_transform()
in image_pipeline.py instead of duplicating crop-box math, so label
placement stays correct (and in-bounds) under all four modes, not just
the two crop ones -- letterbox/stretch never crop a face out, so labels
just use straight scale+offset math there.
Schema migration v5 adds display_mode, backfills it from the old
boolean (True/False -> crop_faces/crop_fill), and drops the boolean.
Verified against the live-shaped test database: the migration
(existing frames correctly preserved as crop_faces), the config page's
new 4-option select, actual renders under letterbox (confirmed real
white letterbox padding in the packed panel-code bytes) and
stretch_fill, invalid-input fallback, and the standing legacy-device
curl suite.
Advanced configuration (Configuration tab, collapsed <details> section):
a color picker per ink color (black/white/yellow/red/blue/green),
overriding image_pipeline.DEFAULT_PALETTE_RGB for that frame's actual
panel -- different units can vary enough from the documented
approximations to be worth calibrating once you can compare a rendered
photo against the real hardware. Stored as Frame.palette_rgb (NULL =
default, schema migration v4), threaded through render_frame/
render_placeholder/_quantize_and_pack (which now builds the PIL palette
image per call instead of once at import) so both photos and the
unclaimed/unconfigured placeholder screen respect it. "Reset to
defaults" clears back to NULL. Config-save validates exactly 6 #rrggbb
values, rejecting anything else with a 400.
Also: each frame's sidebar entry now shows its last-reported battery
percent (🔋NN%) next to the name, using the frame_dot's existing
recently-seen indicator conventions -- silent when never reported
(mains-only frames, or before the first report), matching how battery
is hidden everywhere else it's not applicable.
Verified against the same live-shaped database as the SMTP work: the
v3->v4 migration, save/reload/reset round trip through the real HTTP
route, an actual rendered image using a custom palette (confirmed via
its packed panel-code bytes), input validation, and the sidebar badge
against real battery data -- plus the standing legacy-device curl suite.
Two real fixes to app/mail.py, both found by testing against an actual
mail server rather than just a fake stub:
- Replaces the STARTTLS-only smtp_use_tls boolean with a three-way
smtp_encryption ("none"/"starttls"/"ssl"). Implicit TLS (port 465,
what Purelymail and most providers offer alongside 587/STARTTLS) is a
different handshake entirely -- TLS from the first byte, not a
plaintext connection that gets upgraded -- so it needs its own
smtplib.SMTP_SSL code path, not just a skipped starttls() call.
Schema migration v3 adds the column, backfills it from the old
boolean, and drops the boolean (safe on a live, populated DB).
- Outgoing mail was missing Date and Message-ID headers -- email.mime
doesn't set either automatically, and a missing Message-ID in
particular is enough for a strict content filter (confirmed via a
real Postfix+Amavis mail server's logs: SPF/DKIM/DMARC all passed
cleanly, but Amavis quarantined the message as "BAD-HEADER-0" purely
for the missing id) to silently swallow an otherwise-legitimate
email, even though smtplib reports success -- the send genuinely
succeeds to the relay, it just never survives the recipient's own
filtering. Both headers are now set, with the Message-ID's domain
matching the From address.
Verified: SMTP_SSL path against a hand-rolled implicit-TLS fake server
(self-signed cert, client-side verification relaxed only in the test
harness -- production code keeps ssl.create_default_context()'s real
verification), the v2->v3 migration against live data, the full admin
SMTP-save + test-email round trip over HTTP, and the standing legacy-
device curl suite.
Admin-configured SMTP (server/port/username/password/from address/
STARTTLS, a singleton server_settings row set from /admin -- not env
vars, since it's operator infrastructure a household admin sets up
once through the UI) powers two features, both requiring the relevant
user to have an email set in their own Settings:
- "Forgot password?" on /login emails a one-hour single-use reset link
(password_reset_tokens table). The endpoint always returns the same
generic "check your email" response regardless of whether the address
matched an account, so it can't be used to enumerate registered users.
- A frame's Configuration tab can set a battery-alert threshold
(Frame.battery_alert_threshold_pct, -1 = disabled); POST /frame/battery
emails the owner the first time a report drops to or below it, then
stays quiet for the rest of that discharge cycle (battery_alert_sent,
reset alongside battery_history whenever the existing recharge-jump
detection fires) -- not once per wake.
New app/mail.py wraps stdlib smtplib (no new dependency); send_email()
never raises, so a broken mail server can't 500 a battery report or a
password-reset request. Schema migration v2 adds users.email and the
two frame columns via ALTER TABLE (safe against the live, already-
populated database) plus the two new tables via the existing
create_all-based migration runner.
Verified against a real (already-migrated, real user/frame data)
database: the v1->v2 migration, admin SMTP config + test-email button,
full forgot/reset-password roundtrip (including single-use token
invalidation and the no-enumeration response), and the battery alert
firing exactly once per crossing against a hand-rolled fake SMTP
server -- all via curl end-to-end, plus the standing legacy-device
curl suite to confirm the device protocol is untouched.
Replaces the single global config.json (whole-file pydantic model under
one RLock) with SQLite via SQLAlchemy 2.0: users/sessions/frames/links/
pending-claims/battery_log tables (models.py), a per-frame lock registry
(db.frame_locked) succeeding config.locked(), and hand-rolled schema
versioning (migration.py). A pre-database deployment's config.json is
imported verbatim as frame #1 on first boot and left untouched as the
rollback path; the old single firmware.bin slot becomes per-frame
firmware/<id>.bin.
Routes split out of the 900-line main.py into routers/device.py (the
frozen /frame/* protocol) and routers/api.py (web UI, still on the old
single-frame paths for now). Device auth moves to require_device, which
already speaks the full multi-frame protocol: per-frame device tokens
pushed via /frame/config and acknowledged on first use, self-
registration of unknown device ids as unclaimed frames, pending-claim
attachment, and the legacy-token migration window that keeps the
currently-deployed firmware (no id, shared MANAGEMENT_TOKEN) resolving
to frame #1 -- including the one-time binding of its device id when it
first reports one after a future OTA.
Externally identical for existing deployments: same paths, same token
semantics, same response shapes -- verified with a migration fixture,
the legacy-device curl suite, a 20-way concurrent-advance smoke test,
and a mutate-restart-assert persistence check against a fake Immich.
photo_queue.py ports nearly verbatim onto the Frame ORM row (MutableList
JSON columns make its in-place list mutations dirty-track); quiet-hours
math extracted unchanged into quiet_hours.py.
