A washer whose course table includes "Download"/"Downloaded" runs whichever
program the SmartThings cloud last pushed down. Those programs are now
selectable from the ordinary cycle select, so a downloaded Jeans or Sports
cycle can be started without giving the appliance internet access.
The device turns out to enumerate them itself. `CloudExtraCourse_` on
/course/vs/0 lists one byte per downloaded program, and byte 2 of a
program's payload is exactly that slot id -- verified against all nine
programs on the reporter's WW5000C and against the WA55A7700AV dump already
in the corpus. So nothing here is hardcoded: the appliance says which
programs exist, the payloads are learned by watching what it reports, and
the names come from the user.
That last part is unavoidable rather than a shortcut. A payload is only
visible while its program is loaded, and the appliance never reports a name
for one. So cloudcourse.py persists what has been seen (same rationale as
learned.py's mode store), a Repairs issue tells the owner how many programs
are still unaccounted for, and an options-flow step collects the names. A
program appears in the cycle select only once it is both learned and named.
Selecting one issues the only two-token options write in the codebase --
the course token has to switch to Download in the same write, or the
appliance accepts the program token and silently ignores it (confirmed on
hardware). The Download course code is learned by observation but never
applied until the user confirms it: tokens in this array are replaced by
prefix and never evicted, so a stale program token can appear alongside an
unrelated course, and acting on that would start the wrong wash cycle. For
the same reason a stale token is never reported as the running program.
Also of note:
- There is no single "Download" course code. The WW5000C uses 87, the
WA55A7700AV uses 17 -- same Table_02. Any per-table lookup would have
been wrong on one of the only two devices available to check.
- Payloads are replayed byte-for-byte and never decomposed or rebuilt.
Bytes 5/7/9 do decode to temperature/rinse/spin on the WW5000C, 9 for 9,
and produce nonsense on the WA55A7700AV -- so that decode is written up
in docs/investigations/download-cycle.md and not shipped, and the
read-only sensors it would have enabled were dropped.
- The store reaches the registry as a namespaced synthetic field merged
onto /course/vs/0's rep at read time, so exists_fn/rep_fn/options/write_fn
all see it through their existing signatures. It never enters the state
cache, so it can't be polled over, written to the device, or land in a
diagnostics dump.
- A name that would render identically to another cycle in the same
dropdown is rejected in the flow: the select maps a chosen label back to
a raw value by matching display text.
Non-English catalogs carry the new strings in English for now; they need
real translations.
washer_cycle_fallback no longer wraps an unrecognized code in an
'Unknown (0xNN)' label -- that baked untranslatable English into a
component built to be fully translatable. It now only ever surfaces a
device-provided personal-course name; an unrecognized standard code
displays as its raw value, same as before PR #251.
Also translates nl.json's '69'/'88' washer labels left in English (same
review), and makes de.json's own 'smart' states consistent with the
'Intelligente Lüftung' translation already used for smartventilation.
PR #251 and PR #275 predate this repo's ruff-format adoption on those
files; running the formatter (single->double quotes, line wrapping,
trailing-comma cleanup) keeps the merged code consistent with the rest
of the codebase. No behavior change.
Same isinstance/cast narrowing and Optional-field assert pattern as the
prior commits, covering the airconditioner, fridge, washer, operational,
subdevices, sensor_hysteresis, laundry, select_options, identity and
entities test files.
Adds [tool.ruff] and [tool.ty] config to pyproject.toml with a curated
ruff rule set (E, F, W, I, UP, B, C4, SIM, RUF, ASYNC, LOG, G, PIE, RET,
PERF, N), pins ruff/ty in requirements-dev.txt, reformats the whole tree
with `ruff format`, and fixes the pre-existing lint and type-check debt
those tools surfaced so both run clean.
Production-code type fixes include: HA's ConfigFlowResult vs. the
generic FlowResult in config_flow.py, narrowing BoundEntity.desc to its
platform-specific subclass (SelectDesc/NumberDesc/SensorDesc/etc.) via
cast() instead of an unchecked annotation, converting HA device_class
strings to their proper enum types, a resolve_registry callback typed
as `object` instead of `DeviceRegistry | None`, and a couple of other
narrow correctness fixes (CA key type validation, an index-out-of-bounds
false positive from an empty-tuple fallback, a bool/dict argument swap).
Test-file fixes are mechanical: narrowing SamsungEntityDescription to
the correct subclass via isinstance()/cast() before accessing
subclass-only fields, and asserting Optional write_fn/unit_fn fields
are set before calling them.
Simplification (feedback: this was overcomplicated): drop the
validated_table gate entirely. cycle_select's table_href now just builds
the translation key directly from whatever course table the device
reports (washer_cycle + Table_02 -> washer_cycle_table_02) instead of
comparing against a hardcoded known-good value and falling back to no key
on any mismatch. A table we haven't shipped translations for yet (e.g.
FlexWash's Table_00) still gets a key built for it -- Home Assistant's own
missing-translation handling takes it from there, the same graceful
fallback already relied on for any individual untranslated code within an
existing table. Adding a newly-confirmed table later is just new
strings.json entries, no code change.
Independent (Opus) review of the prior version caught two real issues,
fixed here regardless of the simplification above:
- translation_key was resolved once at entity construction from whatever
coordinator.last_resources held at that moment. Discovery can run while
a sibling resource is still an empty stub (documented precedent: see
_is_included), so a callable translation_key could permanently bake in
a stale value for the entity's lifetime. Moved resolution into a
translation_key property override (Entity.translation_key is a property
upstream, not a plain attribute), re-evaluated against live coordinator
data on every access, matching how options/current_option already work.
- The supportedOptions fallback's "smallest passing K wins" docstring
claimed every larger passing K is an exact multiple of the true one.
False: the shipped dishwasher fixture has passing K=7 (true) alongside
10, 14, and 35, none of which are multiples of 7 -- position 0 always
lands on the same real course code regardless of K, which alone
satisfies the current-course guard for several unrelated splits.
Corrected the reasoning to what's actually true (an empirically-matched
heuristic across six real dumps, not a proof) and added a regression
test locking in the real dishwasher case so this isn't silently lost.
Course codes on the shared /course/vs/0 contract aren't guaranteed
consistent across board generations: washer/combo devices report course
table Table_02, dryer devices Table_03 (x.com.samsung.da.st.courseTable,
previously fully ignored), and every code in washer_cycle/dryer_cycle was
confirmed exclusively against those. FlexWash's older DA_WM_A51 board
reports Table_00 instead -- applying the same translations there risked
showing a wrong name for any code that happens to numerically collide
between tables, not just an untranslated one.
SelectDesc.translation_key can now be a callable (resources -> key or
None), mirroring the existing pattern for `options`. laundry.cycle_select
gains optional table_href/validated_table params: when given, the renamed
washer_cycle_table_02/dryer_cycle_table_03 keys only apply when the
device's own course table matches exactly -- a different table, or no
table id at all, gets no translation_key (raw code display) rather than
a guess. dishwasher's call site is unchanged (static key, unconditional):
no equivalent table-id resource exists in any dump seen, and no evidence
its course codes vary by table the way washer/dryer's do.
entity.py and select.py resolve a callable translation_key once (via
coordinator.last_resources) and reuse that resolved value everywhere
_display() needs it, rather than re-checking the raw descriptor field.
Some DA_WM_TP1/TP2-class boards populate /wm/editcourse/vs/0 without ever
filling in editCourseList itself (issue #1), so the Cycle select never gets
created even though the device clearly has one (confirmed via SmartThings
app screenshots and a currently-selected course).
/course/vs/0's own x.com.samsung.da.supportedOptions turns out to already
carry the course list, just undocumented: a 1-hex-nibble header followed by
one fixed-width record per course, self-indexed by a course-code first byte
rather than positional like editCourseList. Confirmed against six
independent real-world dumps pulled from open and closed GitHub issues.
cycle_options() now falls back to deriving this when editCourseList is
empty, gated on two checks: the derived codes must all be distinct, and
must include whatever course is currently selected. Larger multiples of
the true record width trivially re-pass both checks too (they're just a
sparser sampling of the same table), so the smallest passing width wins
rather than requiring one unambiguous match.
Also fires on the washer_flexwash fixture, newly creating a Cycle select
there -- unconfirmed against any ground truth for that device (a different,
older board generation with no editCourseList and no screenshots to check
against), flagged for follow-up discussion rather than silently accepted.
First full dryer dump (issue #14, DV90BB5245AES1) surfaced 5 unbound
hrefs and an "incomplete capability coverage" repair. Handle them and,
while here, make the washer/dryer/dishwasher families consistent instead
of each carrying a bespoke variant of the same controls.
Dryer coverage:
- /power/0, /kidslock/0, /remotectrl/0: bind via the OCF-native + vendor
fallback pairs (prefer the standard OCF resource, fall back to -vs).
- /buzzersound/vs/0: new Buzzer sound select.
- /course/vs/0: cycle select shared with washer/dishwasher; ignore the
/st/dryercourse/vs/0 re-encoding (mirror of /st/washercourse/vs/0).
Consistency / de-duplication:
- Move generic OCF controls (power/kids-lock/remote-control fallback
pairs, energy meter) into common.py; every registry uses them.
- Move shared laundry controls (buzzer, job-beginning-status, and the
/course/vs/0 cycle-select machinery) into laundry.py; washer and
dishwasher stop hand-rolling their own copies.
- Energy meter is now sentinel-aware everywhere: the dead '-500'
instantaneousPower reading no longer shows a misleading 0 W (fixes it
on dryers and dishwashers, matching the earlier washer fix).
- Job-beginning-status reads x.com.samsung.da.currentStatus, the field
every dump actually carries; the dryer sensor was previously blank.
Adds a scrubbed dryer fixture, golden, and capability tests, plus an
.claude/skills/adding-device-support skill capturing the dump-reading,
OCF-vs-vendor, entity-taxonomy, and coverage workflow. Bumps to 0.6.0.
