Hi There, I am about to renovate my new apartment and will install rgbw lights in every room. since the knx rgbw controllers are pretty expensive (I need about 6 of them) and are missing some features like color changing effect/easy group control, I decided to buy wifi controllers that work with tuya. I can control them in HA perfectly fine, but I want to be able to control them with my “MDT Glastaster” too. I have integrated my knx to HA as far as I can but I have no clue how to carry on 
.
Of course I read the KNX integration but I still have no clue how I can send the actual light settings of my rgbw controller from HA to KNX and process my light settings form knx on to the controller. On yt I read that it’s not that easy but somehow possible.
my .yaml config for the light:
knx:
light:
- name: “Deckenleuchte Bad”
address: “1/1/27”
state_address: “1/4/27”
rgbw_address: “1/5/0”
#rgbw_state_adress: “1/6/0” (error code is shown in HA so I used #…)
brightness_address: “1/2/22”
brightness_state_address: “1/3/22”
so that’s how I think I can control the light over knx… but how do I connect the output of knx to my controller.
Is there someone around who can help me? I would be really grateful.
