Note: this PR was opened by an automated Claude Code run. It needs human review and testing on a real Matter device (no physical AirQuality sensor was available to validate the mapping end to end).
Description
The Matter AirQuality cluster (id 91 / 0x005B) exposes a single airQuality attribute, an enum holding the overall air quality verdict the device computes itself: Unknown(0), Good(1), Fair(2), Moderate(3), Poor(4), VeryPoor(5), ExtremelyPoor(6). The Matter integration already handled the individual concentration clusters (PM2.5, PM10, CO2, VOC, NO2, formaldehyde) but not this overall verdict.
Taxonomy choice — a new type, not a new category.docs/specs/device-feature-categories.md lists voc-matter-index-sensor / no2-matter-index-sensor as legacy exceptions that must not be used as precedents for new protocol-named categories, and rule 5 says not to create a category when a new type on an existing one is enough. So this adds a level type to the existing airquality-sensor category, next to the numeric aqi type:
DEVICE_FEATURE_TYPES.AIRQUALITY_SENSOR.LEVEL = 'level', values from the new AIR_QUALITY_LEVEL constant;
the value scale is Matter's, which is also how Zigbee air quality sensors report an overall level (rule 3: align with the standard by default);
inline scope comments on both the new constant and the two types state the boundary: aqi holds the numeric index, level the qualitative verdict, an integration maps whichever form its device natively reports and never both, and the raw concentrations behind the verdict keep going to their own per-pollutant categories;
units declared in DEVICE_FEATURE_UNITS_BY_CATEGORY_AND_TYPE (aqi → AQI, level → none).
Per-device value set through supported_options (rule 6). Only Unknown, Good and Poor are always part of the Matter enum — Fair, Moderate, VeryPoor and ExtremelyPoor are each behind an optional cluster feature. The new airQualityMatterMapping.js builds the feature's supported_options from the cluster's supported features, exactly like getAcModeSupportedOptions does for the air conditioning mode, and min/max follow that list.
Server changes:
server/services/matter/utils/convertToGladysDevice.js: discovery of the AirQuality cluster as a read-only airquality-sensor/level feature;
server/services/matter/lib/matter.listenToStateChange.js: subscription to the airQuality attribute;
server/services/matter/lib/matter.readInitialDeviceStates.js: initial read so the feature has a value right after pairing;
server/services/matter/README.md: AirQuality row moved to handled, counters and percentage updated (27 / 132 = 20.5%).
Front changes (full plumbing per rule 8):
type label and the seven value labels in en, fr and de;
icon in front/src/utils/consts.js;
dashboard badge: BadgeNumberDeviceValue now allows a type-specific color method, so the level does not get read on the numeric-index scale (where it would stay green forever). The level uses the same palette as the AQI index, and an out-of-enum value falls back on the shared "unknown" label instead of an empty badge;
MQTT device page: default min/max/read_only and catalog preview value/label for the new type.
Scene triggers and the history grouping needed no change: getDeviceFeatureValueOptions picks up the numeric value labels automatically, and airquality-sensor is already in the climate history group.
Tests pass: cd server && npm run coverage (Codecov requires 100% coverage on changed lines) and Cypress (npm run cypress:run) if the UI changed
Ran the Matter suites (test/services/matter/**, 270 passing) plus test/utils, test/lib/device, test/services/mqtt and test/services/homekit (1043 passing). nyc reports 100% line coverage on every touched server file (convertToGladysDevice.js, matter.listenToStateChange.js, matter.readInitialDeviceStates.js, airQualityMatterMapping.js), including the fallback branch where the cluster declares no optional level feature. The full npm run coverage and Cypress were not run in this environment — CI will cover them.
Linter and prettier pass on both front and server (npm run eslint, npm run prettier)
npm run eslint and prettier --check pass on server/ and front/ (0 errors; only pre-existing warnings), and npm run compare-translations passes for en/fr/de.
No undocumented breaking change
Adding a type to an existing category is additive; no existing feature, selector or value changes.
The Matter AirQuality cluster (0x005B) reports an overall air quality
verdict as an enum (Unknown, Good, Fair, Moderate, Poor, VeryPoor,
ExtremelyPoor). Gladys already handled the individual concentration
clusters (PM2.5, PM10, CO2, VOC, NO2, formaldehyde) but not the overall
verdict.
Rather than a new protocol-named category (the existing
voc-matter-index-sensor / no2-matter-index-sensor are documented as
legacy exceptions in docs/specs/device-feature-categories.md), this adds
a `level` type to the existing `airquality-sensor` category, next to the
numeric `aqi` type. The value scale is the Matter one, which is also how
Zigbee air quality sensors report an overall level.
Only Unknown, Good and Poor are always part of the Matter enum, the four
other levels are optional cluster features, so the device declares what
it can publish through `supported_options`, like the air conditioning
mode feature already does.
Front side: type label and value labels in en/fr/de, icon, dashboard
badge colors (same palette as the numeric air quality index) and MQTT
catalog defaults.

The change adds qualitative air-quality levels to Gladys. Matter clusters now create and update read-only air-quality level features. MQTT defaults, frontend badges, icons, and English, German, and French translations support the new feature.

A rabbit checks each air-quality sign,
Unknown to good, the levels align.
Matter sends each value through,
Badges show the matching hue.

Stale comment
Taxonomy looks right: a new level type on the existing airquality-sensor category, Matter's 0–6 scale as the Gladys-wide enum, optional levels via supported_options, and no protocol-named category. That matches docs/specs/device-feature-categories.md (rules 3, 5, 6, 7).
Change requested — MQTT catalog plumbing still stamps the AQI unit on level features. getDefaultUnitForFeature never consults DEVICE_FEATURE_UNITS_BY_CATEGORY_AND_TYPE, and airquality-sensor/level is not in CATEGORIES_WITHOUT_UNIT, so it falls through to DEVICE_FEATURE_UNITS_BY_CATEGORY['airquality-sensor'][0] (aqi). The empty per-type list then hides the unit picker, so the user cannot clear it. Same pattern as water-heater mode: add the type to CATEGORIES_WITHOUT_UNIT (or teach getDefaultUnitForFeature to honor an empty per-type list).
Follow-up, not a merge blocker for Matter inbound: HomeKit still maps only airquality-sensor/aqi. buildAccessory drops any type missing from capabilities, so a Matter AirQuality device (which this PR maps as level, never aqi) will not expose HomeKit's required AirQuality characteristic. HomeKit's scale is also 0–5 (Excellent…Poor), not Matter's 0–6 — that conversion needs a conscious table, not a passthrough.
Not risk:high: additive type, no migration, no auth. Adding needs:human-review for the enum freeze (Matter 7-level vs HomeKit 5-level, "never both with aqi") and because this was not validated on a real AirQuality device. Requesting atrovato.
Nits: the AIR_QUALITY_LEVEL comment says UNKNOWN must not be charted, but Matter features still keep history and min is UNKNOWN (0), so a line chart will treat warm-up/fault as "better than Good". French value labels agree with qualité (f) while the type is Niveau (m) — fine if intentional.
The `airquality-sensor/level` type was missing from `CATEGORIES_WITHOUT_UNIT`,
so the MQTT device page fell back on the category default and created the
feature with the `aqi` unit. The per-type unit list being empty then hid the
unit picker, leaving no way to remove it and labelling a 0-6 enum as an AQI
index in history charts.
Also reword the `AIR_QUALITY_LEVEL` comment: `UNKNOWN` stays part of the value
range (feature `min` and `supported_options`) so scenes can match it, so it does
appear in history charts and the comment now says how to read it instead of
claiming it is never charted.
Autofix-Pass: 1
The reason will be displayed to describe this comment to others. Learn more.
The MQTT catalog unit leak is fixed: airquality-sensor/level is now in CATEGORIES_WITHOUT_UNIT, so applyDefaultUnit no longer stamps aqi on a qualitative enum. The AIR_QUALITY_LEVEL comment now matches the contract (UNKNOWN stays in min / supported_options; a charted 0 is “no verdict”, not better-than-Good).
Taxonomy still looks right: a level type on the existing airquality-sensor category, Matter’s 0–6 scale as the Gladys-wide enum, optional Fair/Moderate/VeryPoor/ExtremelyPoor via supported_options, and no protocol-named category. That matches docs/specs/device-feature-categories.md (rules 3, 5, 6, 7, 8). CI is green (front, server, Cypress, Docker, codecov patch).
Follow-ups, not merge blockers. HomeKit still maps only airquality-sensor/aqi. buildAccessory drops unmapped types, so a Matter AirQuality device (this PR maps level, never aqi) will not expose HAP AirQuality. HomeKit’s scale is also 0–5 (Excellent…Poor), not Matter’s 0–6 — that needs a conversion table, not a passthrough. Already-paired Matter nodes will show as changed on the Matter devices page (compareDevices sees the extra feature) and can be re-saved there.
Not risk:high: additive type, no migration, no auth. Keeping needs:human-review for the enum freeze (Matter 7-level vs HomeKit 5-level, “never both with aqi”) and because this was not validated on a real AirQuality device. atrovato is already requested.
