HSB Colour + White channel in KNX: What's the "right" way?

Dragonos · November 4, 2021, 10:37am

Okay, tested the new version: Nothing happens. No warning or error in the log, no data is being sent to KNX.

Problem solved. Thank you.

@J-N-K I had a chance to do some testing with “org.smarthomej.binding.knx-3.2.7-SNAPSHOT.kar”

I have the following group addresses:

things:

Thing knx:device:knxlightingrgbw "KNX Lighting RGBW" (knx:ip:knxrouter) {
 Type color  : KNXLightningRGBWKitchenNiche   "RGBW - Kitchen Niche" [ 
               switch="1.001:5/1/68+<5/1/73", 
     increaseDecrease="3.007:5/1/69", 
             position="5.001:5/1/70+<5/1/74", 
                  hsb="251.600:5/1/78+<5/1/79" 
     ]

items:

Color     KNXLightningRGBWKitchenNiche                   "Rgbw kitchen niche"                                                                     {channel="knx:device:knxlightingrgbw:KNXLightningRGBWKitchenNiche"}

openhab> things list | grep -i rgbw
knx:device:knxlightingrgbw (Type=Thing, Status=ONLINE, Label=KNX Lighting RGBW, Bridge=knx:ip:knxrouter)

openhab> items list | grep -i niche
KNXLightningRGBWKitchenNiche (Type=ColorItem, State=65,78,0, Label=Rgbw kitchen niche, Category=null)

results:

no changes in the colour picker seem to propagate to the light.
no changes in the switch affect the light (knx wall buttons still work but changes don’t show up log file)

What else can I do/provide to help debugging?

It seems that MDT (is your device MDT?) and me have a different interpretation of the 251.600 datatype. See this comment.

imaginator · November 9, 2021, 12:17pm

I’m using a MDT DALIControl32 (I think the other poster was using their non DALI RGBW controller) and from the ETS side of things the “0x0E” approach seems to work correctly:

or with hex

(and the lights change correctly)

J-N-K · November 9, 2021, 12:19pm

That’s strange. Do you see the telegram from openHAB in the ETS? Is there any difference?

imaginator · November 9, 2021, 12:34pm

Here’s a wireshark dump of what’s happening.

J-N-K · November 9, 2021, 12:35pm

And what did you send?

imaginator · November 9, 2021, 12:37pm

That was me randomly choosing colours on the colour wheel.

I can do a more controlled test. How about I select 100% of the RGB options. That way we can see what’s going on.
