How to send percentage values via "knx.send" service?

you should still be able to turn the HUE lights on and off and even dim them with the KNX switches. That at least is still working for me atm. That nothing is happening at all for you is quite odd though. Do you see anything in the logfile?

No I see nothing in the logs, dunno want’s wrong, but if color is broken maybe it’s easier for me to use automation for the few Hue lights that I have. Thank you very much for your help anyway, and if one day you update your code do not hesitate to share, it’s always appreciated :wink:
Best regards !
