_serial_from_unique_id took the entry's unique_id at face value. That is
right for an entry whose unique_id holds a real serial, but the unique_id
records what the config flow believed when it ran, not what the registry
holds now -- and for two firmware families those are different things.
Entries added before the placeholder rules landed (issues #83/#189) were
keyed on the placeholder itself: `localthings_Nothing(SVC)` for the
ARTIK051_DONGLE_REF dongles, `localthings_FFFFFFFFFFFFFFF` for the
DA_WM_A51_20_COMMON laundry boards. The coordinator has been resolving
those same boards to the host ever since, so their devices and entities
are host-keyed today. Migration read the placeholder back off the
unique_id, decided the host-keyed rows were the stale ones, and rewrote
them onto the placeholder -- reintroducing exactly the collision those
issues exist to prevent, since every unit of the family reports the same
placeholder and would go back to sharing entity unique_ids.
Run the recovered string through resolve_serial, which is the whole point
of that helper being shared. The old `host:port` special case stays: it's
a config-flow-history artifact rather than a device-reported serial, so
resolve_serial can't recognize it.
The repair pass had a second, narrower way to lose data. Removing a device
takes its entities with it (entity_registry.async_device_modified), and
the removal branch ran after the entity pass -- so an entity that had just
been re-keyed rather than removed, because its serial-keyed key was free,
was destroyed a few lines later along with the entity_id, name and area
the rewrite existed to preserve. Move surviving entities onto the device
they now belong to before removing the duplicate.
Reachable when the serial-keyed device exists but a given entity's
serial-keyed key doesn't -- e.g. the user deleted the visible duplicate by
hand, which is the first thing anyone hitting #236 tries.
Also fold the modelNum `<model>|<board>` split into resolve_model beside
resolve_serial. The config flow and _run_discovery each had their own copy
under a comment promising they matched; a device that renames itself on
the first poll is what a drift there looks like.
The Czech catalog was the only file in the repo still using CRLF, which
made every edit to it show up as a whole-file rewrite in diffs and hid the
one line that actually changed.
Content is byte-identical apart from the line endings, and the file now
matches the exact json.dumps(indent=2, ensure_ascii=False) formatting the
other four catalogs already use.
Adding a device had one message for nearly every way it could fail: "Cannot
connect to the device. Verify the IP address is reachable and the CA
credentials are correct." That covers an IP with nothing on it, an
appliance on cloud-only firmware, a device still holding the session from
the last attempt, a device that answered and rejected our certificate, and
Home Assistant having no internet to reach Samsung's cloud. Only one of
those is fixed by checking the IP and the CA credentials, and the message
gave no way to tell which one you had.
The probe already gathers enough to tell them apart, so classify it:
- cert_rejected the appliance sent a certificate alert. The CA
credentials aren't the AC14K_M CA it trusts, or they
don't pair. Far and away the most common real setup
mistake, and previously indistinguishable from a typo
in the IP address.
- handshake_failed a fatal alert unrelated to the certificate (protocol or
cipher mismatch) -- no amount of fiddling with CA
credentials will fix it.
- handshake_timeout the ClientHello probe proved a DTLS server is right
there, but the handshake never finished. Usually the
appliance is still holding the association from a
previous attempt; it clears on its own in about a
minute.
- ports_closed ICMP port-unreachable on the whole range: something is
at that address and it isn't exposing a local API.
Cloud-only firmware (TCP 8888 only) lands here.
- no_dtls_server some ports open|filtered, none speaking DTLS -- likely
another device on that IP.
- no_response nothing came back at all.
- cloud_unreachable couldn't reach Samsung's cloud gateway for the UUID.
An internet problem on HA's side, not the appliance's.
- unexpected_response authenticated fine, then returned something we can't
read. Neither connectivity nor credentials.
Certificate alerts are read back out of the error text OpenSSL puts in
DtlsCoapSession's ConnectionError, not by re-probing. The library's
diagnostic probe would report the alert authoritatively, but it drives the
handshake far enough to commit association state on the device -- and an
orphaned association is exactly what makes the *next* attempt time out
(RFC 6347 4.2.8), which is a bad trade on a path the user is about to
retry.
Telling ports_closed from no_response needs the UDP sweep to separate a
refusal from an unreachable. Both leave a port "not live", but ECONNREFUSED
is a *response* -- the host is there -- while EHOSTUNREACH/ENETUNREACH mean
the datagram never left. A wrong IP on the local subnet never answers ARP
and fails every send that way, so treating the two alike would have told
those users their appliance was on cloud-only firmware. The sweep now
returns live/refused/unreachable separately, and the preferred-port rescue
moved out of it into _sweep_ports: the rescue is a candidate-selection
decision, and folding it into the sweep's verdict destroyed the evidence
the message is built from.
Every failure carries the error key that fits it, so the flow maps
exceptions instead of guessing, and logs the specifics (alert name, per-port
outcome, response code) at warning level -- the messages that mention the
log now have something to point at.
Certificate re-minting for a reused leaf is also narrower and more correct
as a result: it now triggers on CertRejected specifically, rather than on
"every attempt raised ConnectionError and a port was confirmed".
All five translation catalogs carry the eight new messages. The non-English
ones are my own work rather than a native speaker's; corrections welcome.
Two problems, one setup path.
Port detection (issue #211): the config flow found the DTLS port by
elimination -- a 1-byte UDP probe can't tell a silent port from a real
DTLS server, so every port it couldn't rule out got a full certificate
handshake, and every false positive cost the whole 12s HANDSHAKE_TIMEOUT_S
before the next was tried. Adding an appliance took 30-40s.
smartthings-local 0.1.2 ships a stateless ClientHello probe that settles
this positively: a real DTLS server answers with a HelloVerifyRequest in
~1 RTT, and per RFC 6347 4.2.1 it does so without allocating association
state, so the probe leaves nothing behind on the appliance. The whole
49152-49160 range is probed at once and exactly one confirmed port is
given a certificate handshake. Fanning out is safe here in a way racing
real handshakes is not -- each probe is bounded by a 3s budget, so the
pool costs one probe's wall clock rather than the sum of the range, with
no losing threads left running behind us.
The UDP sweep stays as the fallback for when the probe confirms nothing:
it errs in the opposite direction (it reports everything it can't rule
out), so it still surfaces a device on a path that eats our ClientHello,
and it keeps its issue #192 preferred-port rescue.
Port detection now runs first and needs no credentials, so an unreachable
host fails before any round trip to Samsung's cloud. And a second
appliance reuses the existing entry's leaf cert rather than re-minting --
every device accepts the same one -- which makes adding one independent
of Samsung-cloud reachability. A confirmed-live device rejecting the
reused leaf (the UUID does rotate) re-mints and retries once, so reuse
stays self-correcting; a timeout doesn't, since a fresh cert can't fix
nothing answering.
Identity (issue #236): the coordinator seeded device_serial with the
configured host and only replaced it after the first successful poll. But
device_serial mints *permanent* registry keys -- entity unique_ids and
device identifiers -- so anything registering before that poll returned
was written into the registry keyed on the IP address forever. The
connection-mode sensor is added unconditionally rather than from `bound`,
so it was the reliable victim: when the serial-keyed identity appeared
moments later HA created a second device and entity, and the IP-keyed
pair was orphaned. Deleting them didn't help; the next restart that lost
the race recreated them.
The probe already learns the identity, so store it on the config entry --
serial, model, manufacturer, device type. The coordinator seeds
device_serial and its DeviceInfo from those at construction, so keys are
correct from the first entity that registers even if the first poll is
slow or fails outright. There is no placeholder left to correct.
Discovery now treats the registered identity as authoritative rather than
re-keying a device that already has registry entries; it adopts and
persists the polled identity only for an entry that has none, and warns
if a different appliance answers on the same IP.
Entry version 1 -> 2 recovers the serial from the entry's unique_id (the
flow has always keyed it on the probe's serial) and repairs what the old
registration orphaned: IP-keyed devices and entities are rewritten in
place where the serial-keyed key is free -- keeping entity_id, name, area
and every automation referencing them -- and removed where both exist,
since the IP-keyed one has been dead since the restart that made it.
Placeholder-serial boards (issues #83/#189) were keyed two ways at once,
`host:port` on the entry and `host` in the registry; migration collapses
the entry onto the registry's form. One resolve_serial() now serves both
sides, so they can't drift apart again.
The remaining step in the desired pipeline -- probe for subdevices, then
register devices, then populate entities -- already holds:
_enumerate_subdevices_blocking runs before _run_discovery, which runs
before platforms are forwarded. Duplicating it in the config flow would
mean re-running Pattern B's per-href fallback probe, which is the
opposite of what issue #211 is about.
for_device_by_model returns DeviceRegistry | None; accessing .capabilities
directly off the inline call result left the None case unnarrowed. Switched
to the same reg/resources-tuple helper pattern every other by-model test
file in this suite already uses, which ty resolves cleanly.
Two tests added while triaging #244/#226 just re-asserted a translation
string against the catalog entry that had been written moments earlier
(dryer_cycle_table_03's '51'/'53'/'4e', dishwasher_cycle's '83'/'86').
Neither exercises any code path -- they pass by construction and only
break when someone later edits the label text for wording, not when the
actual code/value mapping regresses. tests/test_translations.py already
holds the invariants that matter for catalog data.
Documents the anti-pattern in the adding-device-support skill so future
translation-only fixes don't reach for this pattern again.
'83' and '86' were swapped in the dishwasher_cycle catalog. Both the
original DW9000F-class fixture this table was built from and the issue
#226 reporter's board share the identical DeviceType_0812, and the
original fixture's own editCourseList puts the two codes back to back
(positions 4-5) -- a plausible adjacent-pair transcription slip. The
reporter's live confirmation (selecting 'Normal' ran the physical Express
60 program and vice versa) settles which way: '86' is Express 60, '83' is
Normal.
The energy-sensor part of the same issue was already resolved per the
issue thread (the device genuinely doesn't report usage, so the sensor's
removal was correct) -- not touched here.
The reporter's fridge/freezer combo reports the issue #186 discrete
definite-setpoint pattern on both compartments, but only the cooler half
was modeled -- /temperature/definite/freezer/vs/0 was unbound. Adds
DEFINITE_TEMPERATURE_FREEZER, identical shape to the existing cooler
capability (same fields, just negative supportedList values).
HOMECARE_WIZARD_V2 appears in /mode/vs/0's supportedModes on TP2X_RAC_20K
units but is a capability/option flag echoed from
/configuration/vs/0's airconOptionList, not a selectable HVAC mode -- the
unit's current mode never reports it. Added to a new
_NON_HVAC_OPTION_CODES set that's dropped silently, so hvac_mode/hvac_modes
stop tripping the issue #93 unmapped-mode warning for it on every start.
Also fixes _warn_unmapped logging "None: device mode ..." during setup's
first discovery pass, before the entity is added to hass and entity_id is
assigned -- falls back to unique_id (set eagerly in __init__), so multiple
same-type devices are distinguishable in the log.
Codes 51 (Eco Cotton), 53 (AI Dry+), and 4e (Self Dry) were confirmed by
the reporter selecting each program on the physical appliance and reading
back the resulting raw course code, same table (Table_03) as the existing
issue #80 confirmations.
Also fixes an import-sort lint error left over in by_type/dehumidifier.py
and a stale comment in dryer.py claiming codes 21/4c were still
unidentified when the catalog already had them.
Dryers report the same DrumCleanProposal_/WashingTimes_/DrumCleanLog_
options[] tokens washer.py already models for issue #9, so
drum_clean_cycles_remaining/drum_clean_last_cleaned move to laundry.py and
get bound on dryer's /course/vs/0 too.
DrumCleanLog_ on the reporter's dump is a '|'-joined history of every past
clean rather than washer's single bare timestamp -- the shared helper now
takes the last (most recent) entry, which turns out to also fix a latent
bug on four existing washer fixtures whose own DrumCleanLog_ was already
multi-entry and silently failing to parse into drum_clean_last_cleaned.
No heat-exchanger-clean tracking was found in either dump #258 supplied;
noted in dryer.py so a future report knows this was checked.
TP1X_FAC_TIME_23K reports three previously unbound hrefs: a UV-C
sterilization LED and a ventilation-reminder alarm (both plain On/Off
toggles), and a second PM1-rated dust filter with no live usage/status
fields on this particular dump.
The PM1 filter capability gates each entity on its own field's presence
rather than a blanket ignore, since the TP1X_DA-AC-CAC-01001_0000 cassette
AC (issue #191) reports the same href with full live data -- this also
closes two of that device's ten documented coverage gaps (UV LED and the
PM1 filter) as a side effect.
The previous commit's translation update rewrote this file with LF
endings; every other language file in the catalog already uses LF, but
this one was CRLF before that change.
The TP1X_DA_AC_DHM_01001_0000 revision (model AY70H18100GTD) additionally
reports /display/vs/0 (same shape as air_purifier's screen toggle, reused
directly) and /watertank/lighting/vs/0 (on/off, color, and brightness for
the tank's ambient light, plus a diagnostic alarm-status flag). Both issues
submitted the identical dump, so one fix covers both reports.
Also adds x.com.st.d.dehumidifier to the /oic/d device-type routing table
now that a dump confirms it.
