where can i find the service doc?
i found it, now i have to do a look.
OK,
this is a way to control shelly rgbw, but I’m not sure how I’m supposed to manage that all 4 colors (RGBW) from KNX are to be adopted in this automation.
In KNX all 4 colors come as a single group address.

your needed data in rgbw_color: is a list of 4 int 0…255 too, so just use a template to pass the list (or the first 4 items) to that service.
I dont´t understand it.
i have these:
configuration.yaml
knx:

type: "percent"
# Philipp RGBW - Grün

data:
brightness: 65
rgbw_color:
- 0

I can’t get any further from this point.
How do I get these 4 values in here now. They are individual values and I don’t understand how to deal with them.
You never said that the colors are spread over multiple GAs 🤷
Maybe you can store the values in a helper attribute or something. Not sure if that works though.
If not you could use individual sensors to store the value.
Hello Matthias,
All colors are always separate in KNX. Each color a percent type group address.
how can i do this and once I have that, what’s next?
I don´t have any idea how to do this.
Thank´s for your help.
Is there anybody who can help me whith this problem?
- configure 3 knx sensors. One for each color.
type: percentortype: percentU8(latter is 0-255) - make an automation listening for state changes of these 3 sensors.
- use their states to set a new color for your entity with
light.turn_onservice in the automation action - read documentation about templates on how to do this.
OK, now i have the 4 sensors:
sensor:
- name: "Philipp RGBW - rot"
state_address: "1/0/48"
type: percentU8
- name: "Philipp RGBW - grün"
state_address: "1/0/50"
type: percentU8
- name: "Philipp RGBW - blau"
state_address: "1/0/52"
type: percentU8
- name: "Philipp RGBW - weiß"
state_address: "1/0/54"
type: percentU8
and i have these automation:
- id: '1671048140828'
alias: Philipp RGBW
description: ''
trigger:
- platform: event
event_type: knx_event
event_data:
destination: 1/0/48
action:

target:
entity_id: light.shellyrgbw2_d88e91
data:
brightness: 65
rgbw_color:
- 0
- 0
- 255
- 0
the automation works whith the fixed valus for RGBW colors, but i have no idea how to replace the fixed values with the sensor values.
I can´t find something in docs for how to do this. Maybe I’m looking wrong, but I’m treading water.
Could you possibly give me a solution, or at least give a contribution from which one can derive it in a meaningful way?
Use templates to get the states of your sensors.
rgbw_color:
- "{{ states('sensor.rot') | int(0) }}"
- ...
Here is documentation for this: https://www.home-assistant.io/docs/configuration/templating/
You also don’t need to use knx_event as trigger (and define it in configuration.yaml) when you have sensors defined. You can use
automation:
trigger:
- platform: state
entity_id:
- sensor.rot
- sensor.grün
- ...
Here is documentation for this: https://www.home-assistant.io/docs/automation/trigger/#state-trigger
Thank you very much,
the way with templates is new for me.
Here is my complete solution to control Shelly rgbw.
In configuration.yaml
knx:
sensor:
- name: "Philipp RGBW - rot"
state_address: "1/0/48"
type: percentU8
- name: "Philipp RGBW - grün"
state_address: "1/0/50"
type: percentU8
- name: "Philipp RGBW - blau"
state_address: "1/0/52"
type: percentU8
- name: "Philipp RGBW - weiß"
state_address: "1/0/54"
type: percentU8
In automation.yaml
- id: "1671048140828"
alias: Philipp RGBW
description: ""
trigger:
- platform: state
entity_id:
- sensor.philipp_rgbw_rot
- sensor.philipp_rgbw_grun
- sensor.philipp_rgbw_blau
- sensor.philipp_rgbw_weiss
action:
- service: light.turn_on
target:
entity_id: light.shellyrgbw2_d88e91
data:
brightness: 65
rgbw_color:
- "{{ states('sensor.philipp_rgbw_rot') | int(0) }}"
- "{{ states('sensor.philipp_rgbw_grun') | int(0) }}"
- "{{ states('sensor.philipp_rgbw_blau') | int(0) }}"
- "{{ states('sensor.philipp_rgbw_weiss') | int(0) }}"
Now I need help for the way back.
Do you also have any idea how I send shelly’s status back to the KNX?
First of all, I would have to break down the 4 colors into individual objects again, that’s where the chaos begins for me.
"{{ state_attr('light.shelly...', 'rgb_color')[0] }}"
would get you the red part. [1] green etc.
Have a look at 
to play with templates
And 
to inspect your entities states and attributes.
Thank you, you are the best.
I will try and give feedback.
OK, I also worked with an automation here. Here is my solution Color States from Shelly to KNX.

payload: '{{ state_attr(''light.shellyrgbw2_d88e91'', ''rgbw_color'')[3] }}'

It works fine for me, but is there a way to do it in one “knx.send”?
No.
It’s 3 different payloads with 3 different addresses. It will always need 3 Telegrams.
Be aware not to create a loop with your 2 automations since they use the same GAs.
This is not a Problem, i have diffrent GAs for send and receive.
OK, then i have it. Now the next Step.
Is there a way to control the effects of Shelly rgbw. In the integration the effects are supportet i think in the light. entity.
Many thank´s for your help.
Greetings, Wolfgang
Hi again 
I tried the same approach and the data is written to my LED stripe. But the values are not 100% equal. So e. g. when i fully set “Blue” on my KNX device [0,64,255, 255] my LED stripe is returning me the RGB values [128,160,255]. Where is my mistake?

Here the UI comperison:
I also tried to insert into my automation script the brightness level of my KNX device without any success. My try is commented in the automations.yaml file. Do I have any syntax failure here?
I just simply want to use all my RGBW values of my KNX device to set my LED WiFi Controller stripe to the exact same values. 
But all my tries aren’t fully equal and I don’t know why.
By the way: I normally like programming in NodeRED instead of automations.yaml. How is this RGBW script doable in NodeRED? I faced the issue to merge 4 payloads into 1 RGBW message.
I think this should be brightness_pct: "{{ state_attr(‘light.ha_led_streifen_sideboard’, “brightness) | int(0) }}”, but would be easier to say with an error message 
Do not use knx light entitiy configuration for non-knx entities. This will almost never work well - its not designed for that.
use knx.send with a raw palyoad of a list. Just like
but for payload…
There may be an issue converting RGBW to RGB. Or RGBW without brightness to RGBW with brightness. Or RGBW to RGB with brightness ect… colors are weird…
