Help: Tasmota rgbww controller white light

Good Day,

Got some trouble using the white channel on me rgbw controller the H801.
The white channels are not working, and i can’t figure it out myself.
The value’s are sent to the controller, nothing/ but when i change the color manual in the interface of Tasmota (color 000000) than i can use the slider for the white light.

Is there someone that could help me?

Anyone a idea, why nothing is changing is the white light?
Manual changing it to 000000FF is giving me light

I have a Tasmotised Magic Home RGBW (without IR) and like others I have not managed to set up control of the white channel.
The device can be commanded to control the first three channels RGB and also will respond to DIMMER messages.
Using the console to investigate the behaviour I can successfully control all 4 channels via direct input of the COLOR values. Here are some examples:

01:43:09 CMD: cmnd/sausage/color 336699cc
01:43:09 MQT: stat/sausage/RESULT = {"POWER":"ON","Dimmer":80,"Color":"326598CC","HSBColor":"210,67,60","Channel":[20,40,60,80]}
01:43:42 CMD: cmnd/sausage/color ffffffff
01:43:42 MQT: stat/sausage/RESULT = {"POWER":"ON","Dimmer":100,"Color":"FFFFFFFF","HSBColor":"0,0,100","Channel":[100,100,100,100]}
01:43:54 CMD: cmnd/sausage/color 33333333
01:43:54 MQT: stat/sausage/RESULT = {"POWER":"ON","Dimmer":20,"Color":"33333333","HSBColor":"0,0,20","Channel":[20,20,20,20]}

As can be seen I have direct control over the RGB and W channels - including the brightness of each channel (it automagically adjusts the Dimmer value to suit the overall brightness being assigned to RGB and W - so I don’t think I really need to worry about sending DIMMER commands)

What I am failing to create is a controller in HA that can handle RGB AND W - and I it is driving me nuts!

Here is my current setup for this light - but only the RGB and Dimmer settings actually work!

- platform: mqtt
  name: "Sausage"
  state_topic: "stat/sausage/POWER"
  command_topic: "cmnd/sausage/POWER"
  state_value_template: "{{ value_json.POWER }}"

  rgb_state_topic: "stat/sausage/Color"
  rgb_command_topic: "cmnd/sausage/Color"
  rgb_command_template: "{{ '%02x%02x%02x' | format(red, green, blue)}}"
  rgb_value_template: "{{ value_json.Color }}"

# this next bit does not work!!
#  white_state_topic: "stat/sausage/Color"
#  white_command_topic: "cmnd/sausage/Color"
#  white_command_template: "{{ '000000%02x' | format(white)}}"
#  white_value_template: "{{ '000000%02x' | format(white) }}"
