Hi Peter

Capabilities of Philips Hue light

 ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/1/f133b93277a0ed7db1d8fa9379e904161f571874.png)

Whereas now the light is fully on (at value 1)

Then I created the following:

0/6/12 being the group address I assigned to the Dimming Object Function and 3.001 being the DPT

When I do a manual test using fe. 50 as value I get the lamp dimmed to 50%  
Input value: 50  
Output value: 0,5

So the flow works

However, triggered from the KNX switch it doesn’t  
I can switch the lamp ON/OFF but diming (long pressing it) doesn’t do anything

When I do another diagnostics in ETS however , I can see it only sends +100% and -100% values when dimming.  
Switching (ON/OFF) works fine
