Kommunikationsfehler im Widget

[lukima61]

Hallo Community,
ich habe seit der Umstellung von openHAB 3.4 auf 4.1.1 Probleme mit einem Widget. Das Widget dient dazu, ein numerisches Item schrittweise zu verändern, sowohl im positiven als auch im negativen Bereich. Ich setze das Widget dafür ein, um die aktuelle Temperatur eines Thermostates zu kalibrieren (-3 bis +3, Schrittweite 0.5).
Es funktioniert alles so wie geplant, aber von -0.5 zu 0 und von +0.5 zu 0 kommt die Meldung "Kommunikation fehlgeschlagen" auf dem Bildschirm.

Im Logfile wird folgendes ausgegeben:

Ich kann damit leider nichts anfangen und habe auch nichts in den Foren gefunden.

Die Buttons sind wie folgt codiert:

- component: oh-button
config:
action: command
actionCommand: "=(items[props.itemZahl].state === props.Max ? items[props.itemZahl].state : (items[props.itemZahl].state + props.Step))"
actionItem: =props.itemZahl
style:
font-family: u2400
font-size: 150%
text: ▶

- component: oh-button
config:
action: command
actionCommand: "=(items[props.itemZahl].state === props.Min ? items[props.itemZahl].state : (items[props.itemZahl].state - props.Step))"
actionItem: =props.itemZahl
style:
font-family: u2400
font-size: 150%
text: ◀

Ich habe auch schon mit der Funktion Number() probiert, bekomme aber das gleiche Ergebnis. Hat jemand eine Idee, woran es liegen kann?

[udo1toni]

Versuche bitte mal numericState statt state

[lukima61]

Leider das gleiche Ergebnis, im Logfile auch wieder die gleiche Meldung

[lukima61]

Ich habe jetzt mal ein kleines Script zur Kontrolle geschrieben:

var i;

var thread = Java.type('java.lang.Thread')


items.getItem('TestBerechnung').postUpdate(1.5);
console.info(items.getItem('TestBerechnung').state);
for (i = 1; i <= 5; i++) {
thread.sleep(1000);
items.getItem('TestBerechnung').postUpdate((parseFloat(items.getItem('TestBerechnung').state) - 0.5));
thread.sleep(1000);
console.info(items.getItem('TestBerechnung').state);
}

Die Ausgabe ist wie erwartet so:

2024-02-12 23:12:51.745 [INFO ] [g.openhab.automation.script.ui._Test] - 1.5
2024-02-12 23:12:53.764 [INFO ] [g.openhab.automation.script.ui._Test] - 1.0
2024-02-12 23:12:55.766 [INFO ] [g.openhab.automation.script.ui._Test] - 0.5
2024-02-12 23:12:57.768 [INFO ] [g.openhab.automation.script.ui._Test] - 0.0
2024-02-12 23:12:59.769 [INFO ] [g.openhab.automation.script.ui._Test] - -0.5
2024-02-12 23:13:01.771 [INFO ] [g.openhab.automation.script.ui._Test] - -1.0

An dem Item liegt es also nicht, irgendwas stimmt mit der Widget-Engine nicht.
