Farbtemperatur LED/Panel steuern
Hallo zusammen,
ich möchte gerne meine Beleuchtung mit Farbtemperatur steuern. An/Aus und dimmen funktioniert bereits: "DeviceName": "Bett", "Services": [ { "ServiceType": "Lightbulb", "Handler": "millis", "ServiceName": "Bett", "Characteristics": [ { "Type": "On", "Set": [ "0/0/13" ], "Listen": [ "0/0/14" ], "DPT": "DPT1" }, { "Type": "Brightness", "Set": [ "0/0/20" ], "Listen": [ "0/0/17" ], "DPT": "DPT5.001" } ], "subtype": "" } ], "UUID": ""
Aber wie füge ich die Farbtemperatur steuerung hinzu? Mit meinen MDT Led Controller kann ich folgendes steuern:
| Nummer | Name | Objektfunktion | Beschreibung | Gruppenadresse | Länge | K | L | S | Ü | A | Datentyp | Priorität | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 98 | LED TW 2 | Schalten Ein/Aus | ikea schalten | 0/0/13 | 1 bit | K | - | S | - | - | Schalten | Niedrig | |

| 109 | LED TW 2 Helligkeit | Status Dimmwert | ikea helligkeit status dimmen | 0/0/17 | 1 byte | K | L | - | Ü | - | Prozent (0..100%) | Niedrig |
Kann mir da jemand helfen bzw. mir sagen wo ich das einbauen kann?
Gruß, Matthias
In meine FORK ist der Handler 'CTLight.js' zu finden. Damit lässt sich die Farbtemperatur in Kelvin einstellen, allerdings wurde der Pull request node-eibd für DPT7 von @farmio noch nich angenommen.
Gruß, Matthias
Ist er jetzt schon.
@slev1n möchtest Du Deinen Handler als pull request zur Verfügung stellen?
Danke
Raoul
Ich wäre auch sehr interessiert an der Steuerung von TunableWhite Leuchten - ich habe deinen Handler kopiert und die entsprechenden Zeilen in mein config file kopiert, allerdings bekomme ich dann folgenden Fehler:

ich nutze knxd als Schnittstelle zum KNX-Bus. Müsste es mit diesem Plugin nicht gehen?
Da der Handler von @slev1n bei mir nicht richtig funktionierte, habe ich für meine LED Controller (MDT AKD-0xxx) kurzerhand selbst einen Custom Handler geschrieben, den ich mich euch teilen möchte:
Custom Handler for Tunable White Lights - CWWW.js
/* Lightbulb extension for Tunable White Lights
* Infos:
* - used in combination with KNX LED-Controller MDT AKD-0xxx
* - controls the "absolute" adresses for brightness and color temperature in percent [DPT5.001]
* Issues:
* - The LED-Controller offers smooth switch on and off effects for HCL-Mode (Human Centered Lighting). However, it also sends the current brightness value during that, which triggers the handler to adjust the brightness
* --> Workaround: Deactivate status information during HCL changes.
