Interface AtwHotWaterState

Whether eco hot-water mode is on; null where the wire cannot say (Home).

Whether forced hot-water production is on.

Whether hot-water production is currently inhibited.

Instant of the last legionella-prevention cycle, in epoch milliseconds; null where the wire cannot say — Home has no counterpart in its /context settings, and Classic reads null when no cycle was ever recorded (the year-1 sentinel) or the wire value cannot be parsed. The Classic stamp is BUILDING-local wall clock anchored in the client's configured timezone (ClassicAPIConfig.timezone, the host's zone when unset): exact only insofar as that timezone is the building's — a building in another zone skews the instant by the zone delta, so day-scale reasoning stays safe where sub-hour reasoning does not.

Reported tank maximum, in °C; null where the wire cannot say (Home only advertises the setpoint clamp bound, a different thing).

Derived hot-water operational state, same precedence on both dialects: forced reads dhw, prohibited reads prohibited, else the operation mode decides between dhw, legionella and idle.

Tank-water setpoint, in °C.

Last-reported tank-water temperature, in °C.
