Controlling Philips Hue using OpenHAB in Raspberry Pi - philips-hue

Question

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) {

sendCommand(Toggle_1, OFF);
sendCommand(Toggle_10, OFF);
sendCommand(Toggle_11, OFF);
sendCommand(Toggle_5, OFF);
sendCommand(Toggle_9, OFF);

in pi#raspberrypi:/opt/openhab/configurations/items $ vi demo.items
I have

Switch Toggle_3 "right bulb" (Switching) {hue="3"}

Dimmer CT_Dimm_2 "center bulb" (CTDimmer) {hue="2;colorTemperature;30"}
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!

Answer 1

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.

Answer 2

It is random yes but you also have to pair the bridge. Have you got it do at least one bulb can turn on and off?
Just checking but your switch and scene items are not called switch and scene are they?
The binding is picky and you might have to declare the variable type for each:
var DecimalType hue = new DecimalType(240) // 0-360; 0=red, 120=green, 240=blue, 360=red(again)
var PercentType sat = new PercentType(100) // 0-100
var PercentType bright = new PercentType(100) // 0-100
var HSBType light = new HSBType(hue,sat,bright)
sendCommand(Light_GF_Lounge_C, light)
Though to be frank, the binding is a bit of a pain and you would be better off using the API directly and then setting scenes you have set in an app or something.
Or directly
rule "Set lights"
when
Item Switch_Lounge received update ON
then
var String hueApiCall = "curl##-X##PUT##-d##{\"on\": %s, \"hue\":%d , \"sat\": %d, \"bri\": %d, \"transitiontime\": %d}##http://192.168.1.147/api/YOURPAIREDHUEUSERID/groups/%d/action"
executeCommandLine(String::format(hueApiCall, true, 13088, 212, 100, 10, 2 ))
end
Each of the values in the executeCommandLine match the % placeholders in order, in this example on: true, hue: 13088, sat: 212, bri, 100, transition time: 10, group 2
Using that syntax you can set scenes, alerts, all sorts.
