Hey Patrik,
I would recommend you to use the openhabbian image. Im using it on RPi3 with HM-Mod-RPI-PCB also and it is realy easy to use, so you dont have any problems.

Greetings, Fabian

Thanks for your fast answer.

I have choosen the openhabian image now and installed homegear. But i have some Problems.

I can pair my HM-CC-RT-DN but the device is going offline after some minutes ~15 and i dont know why. Then i have to restart the raspberry, after the restart is the HM-CC-RT-DN already online.

The Second problem - i cant manage the temperature over openhab. I created a new item with the Eclipse SmartHomeDesigner:

/*********** Gruppen **********/

// Räume
Group gWohnzimmer

// Funktionen
Group gWzHeizung

/*********** Items   **********/
Number Wz_heizung_links_actualtemperatur 	"Heizung links Temperatur" 			<temperature> (gWohnzimmer, gWzHeizung ) {channel="homematic:HG-HM-CC-RT-DN:3ff56f5b:NEQ1492883:4#ACTUAL_TEMPERATURE"}
Number Wz_heizung_links_settemperatur 		"Heizung links Temperatur setzen" 	<temperature> (gWohnzimmer, gWzHeizung ) {channel="homematic:HG-HM-CC-RT-DN:3ff56f5b:NEQ1492883:4#SET_TEMPERATURE"}

And a new SiteMap:

sitemap Wohnzimmer label="Wohnzimmer" {
	Frame label="Heizung" {
		Text item=Wz_heizung_links_actualtemperatur label="Aktuelle Temperatur [%.1f °C]"
		Setpoint item=Wz_heizung_links_settemperatur label="Temperatur einstellen" step=0.5 minValue=15 maxValue=30
	}
}

Now i go on “http://IP:8080/basicui/app?sitemap=haus” and want change the Temperature, but nothing happen. I have to create a rule havent i?
I hope you can help me :slight_smile:
