Slider controls volume and brightness

Hi

I have a relative straightforward OH installation,
I just added some RGB and Tunable White LED’s and now the following odd thing occurs:

First I can dim and switch the LED, but I can not set their color Temperature
The odd issue is that when I dim the brightness, it also affect the volume on my radio and vice versa

I haven’t found anything in the logs as to why this happens:

Running OH3 on Raspbian

Items:

Switch 	IpRadio_Power 	"Power"             (Pioneer) 		{ channel="onkyo:onkyoUnsupported:IpRadio:zone1#power" }

        Slider    item=IpRadio_Volume             icon="soundVolume"

Any help is greatly appreciated
Kind regards

First, see what commands are generated to which Items in your events.log when you slide a slider.

What are you using to view your sitemap? (app, browser)

iphone app

Try another viewer, out of curiosity (BasicUI)
Do you happen to have MainUI open somewhere else at the same time? That has a weird slider bug in some OH versions.

From my browser it seems ok, at least the brightness of the CCT . I don’t get the REST error message and dimming and volume work independently
however still no control over color temperature.

I don’t know if anyone has logged an issue here

Sure that shouldn’t be a Dimmer type?
That’s what small values
... Item 'CCT' changed from 0.50000000 to 0.46000000
is about.

in the binding information it points to a Number
https://www.openhab.org/addons/bindings/dmx/#channels

color_temperature tunablewhite Number allows to set the color temperature
