Dieses Attribut gehört zu Gerätetypen des Typs THERMOSTAT, die HLK-Details melden können.
Felder
Feld
Beschreibung
Datentyp
status
Der aktuelle HLK-Status des Thermostats.
string Werte: „OFF“, „HEATING“, „COOLING“
Zeitangaben für Ereignisse
Ein Ereignis für eine Änderung des HLK-Status wird möglicherweise nicht gleichzeitig mit Ereignissen für eine Änderung des Thermostatmodus gesendet.
Manchmal verzögert sich der Start des Heiz- oder Kühlmodus eines Thermostats, um die HLK-Anlage zu schützen. In diesem Fall werden beim Ändern des Thermostatmodus möglicherweise zuerst nur Ereignisse für ThermostatMode - und ThermostatTemperatureSetpoint -Trait-Änderungen gesendet. Die ThermostatHvac -Trait-Änderung wird später als separates Ereignis gesendet, sobald das System tatsächlich eingeschaltet wird. Wenn das HLK-System ohne Verzögerung eingeschaltet wurde, werden alle drei Ereignisse gleichzeitig gesendet.
