Wert von Homematic Gerät bei Funktion abrufen

[HKF8770]

Habe ein Problem,

möchte bei einer Berechnung "edit function node" einen Wert einer Homematic Componente miot einbeziehen.

Habe es versuch wie bei einem Java Skrift mit "var zv = getState("javascript.0.Strom.Zählerstand.Vorjahr"/javascript.0.Strom.Zählerstand.Vorjahr/).val;" doch das geht nicht.

Wie ist der Befehlt oder geht das gar nicht??
