KNX Dimmen über Homekit mit Node Red

Strobel

Moin!

Ich möchte gerne meine KNX Installation durch die Steuerung mit Apple Homekit erweitern und habe erste Versuche mit NodeRed gestartet. Licht an/aus funktioniert schon bestens. Leider komme ich beim dimmen nicht weiter.. ich bin am verzweifeln. Im Einsatz ist node-red-contrib-homekit-bridged und node-red-contrib-knx-ultimate

Kann mir jemand helfen bzw. sagen was ich falsch mache?
Gibt es vllt. hier im Forum Beispiele für sowas?

Danke und Gruß!

Hier mein gescheiterter Versuch.

@Strobel Brightness ist ja der Dimmfaktor und der erwartet einen Zahlenwert zwischen 0 und 100 und nicht "true".

Das KNX kann ich nicht beurteilen, aber wenn Du mit einer Inject-Node einen Zahlenwert an dem 2. Ausgang in Deine KNX Node schickst, müsstest Du es ja simulieren können.

Eventuell musst Du auch ein komplettes JSON schicken:

{
"On": true,
"Brightness": 50
}

Hab das nicht mehr ganz in Erinnerung - aber ich glaub so war das.

Hänge mal diese Inject Node vor Deine Homekit Node:

[
    {
        "id": "254f72d0.378a1e",
        "type": "inject",
        "z": "80abc55e.a68438",
        "name": "Test",
        "props": [
            {
                "p": "payload"
            },
            {
                "p": "topic",
                "vt": "str"
            }
        ],
        "repeat": "",
        "crontab": "",
        "once": false,
        "onceDelay": 0.1,
        "topic": "",
        "payload": "{\"On\":true,\"Brightness\":50}",
        "payloadType": "json",
        "x": 510,
        "y": 240,
        "wires": [
            [
                "825717c0.7f4878"
            ]
        ]
    }
]

Und anstelle der Function Node würde ich den JSON String dann lieber über 2 Change-Nodes aufsplitten - das ist übersichtlicher.

Damit Du weißt was ich meine - hier ein Beispiel wie Du einen JSON in die 2 gewünschten Parameter aufdröselst.
