ReadonlydataReadonlydevicesAll devices managed by this facade.
ReadonlyerrorThe fault as MELCloud words it, in the account's language, when the
dialect carries a text on the unit (Classic ErrorMessages); null
on a dialect that only flags it (Home) and while there is no fault.
ReadonlyexistsWhether the underlying entity still exists in the registry. Non-throwing staleness check — see EntityNotFoundError for the throwing counterpart surfaced by other accessors.
ReadonlyfetchFetch the latest device data after syncing.
ReadonlyflagsBitfield flags mapping each updatable property to its effective flag value.
ReadonlygetFetch energy consumption report. ATA and ATW only.
ReadonlygetFetch the energy report as line chart data (kWh buckets). ATA and
ATW only: types without an energy report resolve an empty chart.
ReadonlygetRetrieve the error log for all devices in this facade.
ReadonlygetGet the current frost protection settings, null when never configured.
ReadonlygetRead this device's current state projected as a group state.
ReadonlygetGet the current holiday mode settings, null when never configured.
ReadonlygetFetch hourly temperature report. ATW only.
ReadonlygetFetch internal temperature report. ATW only.
ReadonlygetMember operation modes in the one group vocabulary (Classic-numbered), treating the device as a group of one — no wire call.
Member filter.
true answers empty when the unit is
powered off.
The device's own mode, alone or absent.
ReadonlygetFetch operation mode usage as pie chart data.
ReadonlygetFetch WiFi signal strength report as line chart data.
ReadonlygetSetpoint bounds enforced for an operation mode — the cross-dialect read: a caller needs no knowledge of which API backs the device.
Optionalmode: ClassicOperationMode | HomeOperationMode
Operation mode to resolve; defaults to the active one.
The interval, or null for a mode outside the known
vocabulary (the setpoint then goes unclamped).
ReadonlygetFetch temperature history as line chart data.
ReadonlygetFetch tile overview data, optionally selecting a specific device.
ReadonlygetFetch current device values from the Classic API; on success the registry model catches up with the answer.
ReadonlyidReadonlyisReadonlyistrue while the unit reports a fault of its own (Classic HasError,
Home isInError).
ReadonlynameReadonlynotifyTrigger a sync callback for downstream consumers.
ReadonlypowerWhether the unit is powered on.
ReadonlyrssiLast-reported Wi-Fi signal strength, in dBm.
ReadonlytypeReadonlyupdateUpdate frost protection settings with temperature clamping.
ReadonlyupdateApply a group state to this device.
ReadonlyupdateEnable or disable holiday mode.
ReadonlyupdateTurn all devices in this facade on or off.
ReadonlyupdateSend updated device values, clamping temperatures to valid ranges.
A change set the synced state already holds is refused with
NoChangesError, before any wire call.
Facade for Air-to-Air (ATA) devices, exposing the ATA group operations on a single device by treating it as a group of one — MELCloud's native group endpoints only address zones (building/floor/area), so a device emulates them against its own state.
