- Add device_map entry: VeSyncAirBaseV2, modes sleep/manual/odorShieldBalanced,
fan levels 1-3, air quality feature (no light detection on this model)
- Add PurifierModes.ODOR_SHIELD_BALANCED ('odorShieldBalanced')
- Make lightDetectionSwitch/environmentLightState/efficientModeTimeRemain
optional in PurifierVitalDetailsResult (Vital Pet omits them) and add the
model's additional fields (VOC, odorLevel, buzzerSwitch, filter day counters,
screen/child-lock preference sub-models)
- Wire VOC into purifier state when present
- Fix case-sensitive mode matching in set_mode (VeSyncAirBypass/VeSyncAirBaseV2):
mode.lower() could never match camelCase mode values like odorShieldBalanced
All changes verified against physical hardware (LAP-P201S-WUS, US firmware):
discovery, full state parse, fan speed set/restore, mode set/restore, display toggle.
…ed on LAP-P201S-WUS)

Add support for Levoit Vital Pet air purifier (LAP-P201S-WUS)
Adds the Levoit Vital Pet (LAP-P201S-WUS) to the purifier device map. All behavior below was validated against real hardware (US region) — mode strings were probed via
setPurifierModebypassV2 calls and confirmed by observing the device and the VeSync app.Changes
device_map.py— newPurifierMapentry:VeSyncAirBaseV2, 3 fan levels,AIR_QUALITYfeature, modessleep/manual/odorShieldQuiet/odorShieldBalanced/odorShieldPerformance, setup entryLAP-P201S, alias "Vital Pet".const.py— newPurifierModesmembersODOR_SHIELD_QUIET,ODOR_SHIELD_BALANCED,ODOR_SHIELD_PERFORMANCE. These are the device's "Auto" mode family: the app presents Auto with a Quiet/Balanced/Performance preference, and each preference is a distinctworkMode. (odorShieldPlus/autoPlusspellings were probed and rejected by the API — the app's "Plus" appears to be a separate toggle, not a work mode.)models/purifier_models.py— madelightDetectionSwitch,environmentLightState,efficientModeTimeRemainoptional (this device omits them) and added fields it returns:VOC,odorLevel,buzzerSwitch,filterRemainDay,resetFilterDate,cumulativeCleanAir,totalCleanAir,errorCodes, screen/child-lock preference objects.devices/vesyncpurifier.py—set_mode()now matches requested modes case-insensitively against the device's mode list before sending. Previously it lowercased camelCase modes (odorshieldbalanced), which the API rejects; this fixes mode setting for any camelCase mode while preserving validation.Testing
workModestrings on hardware; only the three odorShield modes + sleep + manual are accepted.Status
Draft while the device soak-tests in a live Home Assistant install for a few more days; will mark ready for review after that.
