Define Mysensor (rgbw) Things in openhab2

[LastSamurai]

I am currently trying to get my domoticz based network ported to openhab 2. I have installed the binding (2.2) and got openhab to connect to the serial gateway. I am struggling though to get it to use my existing nodes.

I mainly have several RGBW nodes I want to use. I am trying to configure this via the config files, not the paper ui.

Here is my .things file:

Bridge mysensors:bridge-ser:gateway [ serialPort="/dev/ttyUSB0", sendDelay=200 ] {
    /** define things connected to that bridge here */
  	rgbwLight LichtFenster [nodeID=5, childId=1]
  	rgbwLight LichtSchrank [nodeID=6, childId=1]
  	rgbwLight LichtWand [nodeID=7, childId=1]
  }

The ids are correct but they are shown as uninitialzed in the paper ui. Why is that?
When restarting one node it showed up in the paperui but as

mysensors:rgbwLight:gateway:rgbwlight_5_1

Also is this the right way to controll the lights:
.items:

Color LichtSchrank "Licht Schrank" <slider> ["Lighting"] { channel="mysensors:rgbwLight:gateway:LichtSchrank:rgbw" }
Color LichtFenster "Licht Fenster" <slider> ["Lighting"] { channel="mysensors:rgbwLight:gateway:rgbwlight_5_1:rgbw" }

.sitemap

sitemap lights label="Wohnzimmer" {

	Frame label="Licht" {
		Colorpicker item=LichtSchrank
		Switch item=LichtSchrank
	}

	Frame label="Licht" {
		Colorpicker item=LichtFenster
		Switch item=LichtFenster
	}
}

I can change the color (for the second one) but not switch them on/off. I also can't control the one only defined in the things file at all.
Thanks for any help, I am still trying to learn this stuff ;)

Ok I'll answer my question here as I found the error with some help:
it has to be

nodeId
// not nodeID
