Farbtemperatur LED/Panel steuern #54
Comments
|
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, |

Ist er jetzt schon. |

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.

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:
Kann mir da jemand helfen bzw. mir sagen wo ich das einbauen kann?
Gruß,
Matthias
