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.
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.
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.
Course selection is now a writable select entity sourced from each
device's own x.com.samsung.da.editCourseList (via a new options-as-callable
form on SelectDesc, reading the coordinator's full resource snapshot
instead of just the entity's own href), rather than a hardcoded course
table baked into Python. A MostUsed_ field on the same resource was
considered as a fallback but rejected after byte-level analysis showed it
doesn't reliably encode a course list. When a device never populates
editCourseList, the selector isn't created at all (exists_fn now takes
(rep, resources) to check a sibling href, matching the existing
match_fn(rep, resources) pattern).
Display names moved out of Python into strings.json/translations under
entity.select.{washer,dishwasher}_cycle.state.*, matching this
integration's existing translation_key convention (fridge.py's ice_type,
flex_zone_mode, etc.) instead of hardcoding English names in code.
