Controlling Philips Hue using OpenHAB in Raspberry Pi

I want to control the Philips Hue Lux color lamps with OpenHAB. So I wonder what are the steps I should do and if I am missing something.

In pi@raspberrypi:/opt/openhab/configurations/rules $ sudo vi demo.rules

rule "Select scene"
    when
        Item scene received command
    then
        switch(receivedCommand) {
            /*alles uit */
            case 0 : {
            sendCommand(Toggle_7, OFF); 
            sendCommand(Toggle_3, OFF);
            sendCommand(Toggle_1, OFF);
            sendCommand(Toggle_10, OFF);
            sendCommand(Toggle_11, OFF);
            sendCommand(Toggle_5, OFF);
            sendCommand(Toggle_9, OFF);
            }
            /*sfeer */
            case 1 : { 
            sendCommand(LWD_3, 90);
            sendCommand(Color_7, "45.584415,86.033516,70.19608");
            sendCommand(Color_1, "45.584415,86.033516,70.19608");
            sendCommand(Color_10, "45.584415,86.033516,70.19608");

in pi@raspberrypi:/opt/openhab/configurations/items $ vi demo.items

I have
:

/* Hue */
Switch Toggle_1   "left bulb"   (Switching) {hue="1"}
Switch Toggle_2   "center bulb" (Switching) {hue="2"}
Switch Toggle_3       "right bulb"  (Switching) {hue="3"}

Color Color_1     "left bulb"   (Colorize)  {hue="1"}
Color Color_2         "center bulb" (Colorize)  {hue="2"}
Color Color_3     "right bulb"  (Colorize)  {hue="3"}

Dimmer CT_Dimm_3      "right bulb"  (CTDimmer)  {hue="3;colorTemperature;30"}

in pi@raspberrypi:/opt/openhab/configurations $ vi openhab.cfg:

I have:

############################### Philips Hue Binding ###################################
#
# IP address of Hue Bridge (optional, default is auto-discovery)
hue:ip=192.168.1.117
hue:secret=openHABRuntime
hue:refresh=10000

I ran it using sudo ./start.sh and then paired the Hue hub with OpenHAB. I am not what is missing because still I can't control the Hue with OpenHAB.

My main struggle is connecting the web UI to the code in openHAB. Any pointer is really appreciated! Also I have stitched the code above from various tutorials so it possibly would make no sense at all!

Solution

Changing how the UI's look is done with the *.sitemap files. This files define how and which items are shown in the UI: https://github.com/openhab/openhab/wiki/Explanation-of-Sitemaps

As for the rest of the example: - Are you sure about the ip and secret of the Hue bridge? - How many light bulbs are connected to the bridge? Because in the *.items file hue=1 means the first bulb connected to your bridge.
