v1.7.1

Fixed

• FAULT_DESCRIPTIONS entries were unverifiable against any authoritative source and some didn't match genuine firmware text. Replaced with 7 entries confirmed directly from the unit's firmware (HSWUPD.BIN, unpacked with hn/vallox-ventilation-unit's unpack-vallox-firmware.pl); the rest correctly resolve to 'Unknown fault', matching the unit's own web UI, which shows no description for most codes either.

v1.7.0

Added

• ScheduleSlot.CUSTOM (4) and ScheduleSlot.STANDBY (5), and a runtime ScheduleSlot object (previously a type-only union 0 | 1 | 2 | 3) mirroring the existing Mode/Profile pattern. Reverse-engineered from a live unit: clicking through a weekly schedule cell's states while reading back the underlying register showed the cycle is None→Home→Away→Boost→Custom→Standby, six states in total — Automatic is never offered as a schedule slot. STANDBY was confirmed to power the unit off for that hour: enabling the weekly schedule with a Standby slot active caused the unit's ON_OFF register to flip to POWER_OFF within seconds.

Fixed

• ValloxClient.getWeeklySchedule() collapsed any schedule register value other than 1/2/3 (Home/Away/Boost) into 0 (None) — including 4 (Custom) and 5 (Standby), which it would have silently misreported as an empty slot. Now returns the real value. Callers that treat a schedule slot as a direct index into a fixed 0–3-sized lookup (e.g. an icon/label array sized for the old 4-value range) should size it for 0–5 instead.

v1.1.0

Added

• getSerialNumber() / vallox serial — reads the unit's serial number from the
  SERIAL_NUMBER_MSW/SERIAL_NUMBER_LSW register pair.
• getUptime() / vallox uptime — reads cumulative lifetime runtime and runtime
  since the unit's most recent power-on, in hours. Exposed via the new UnitUptime type.
• getFilterChangeInterval() / setFilterChangeInterval() and
  vallox filter interval / vallox filter set-interval <days> — read/write the
  configured filter change interval in days.
• npm run docs — generates HTML API documentation from source JSDoc comments via
  TypeDoc (see typedoc.json). Run through a pinned npx TypeDoc/TypeScript pair
  rather than as a devDependency, since the project's own typescript (^7.0.2)
  doesn't yet expose the Compiler API TypeDoc needs.

Security

• Bumped ws (the runtime WebSocket dependency used by WebSocketTransport) from
  7.5.10 to 7.5.13, fixing a memory exhaustion DoS via tiny fragments and data chunks
  (GHSA-96hv-2xvq-fx4p).
• Updated dev-only transitive dependencies (@babel/*, browserslist, caniuse-lite,
  js-yaml, picomatch, brace-expansion, and others) via npm audit fix, resolving
  several high-severity advisories (ReDoS/DoS) in the test/build toolchain. These do
  not affect published package consumers.
