AIlight model E27 , do not work properly with home assistant

[gnkarn]

Describe the bug
the mqtt configuration for this light is not clear , as it white property is not adequately reflected on the docs .
by using the home assistant mqtt light configuration as follows :

• platform: mqtt
  name: "luz living1"
  optimistic: false
  state_topic: "stat/RGBliving1/POWER"
  command_topic: "cmnd/RGBliving1/POWER"
  state_value_template: "{{ value_json.POWER }}"
  on_command_type: "last"
  qos: 1
  payload_on: "ON"
  payload_off: "OFF"
  brightness_state_topic: "stat/RGBliving1/DIMMER"
  brightness_command_topic: "cmnd/RGBliving1/DIMMER"
  brightness_value_template: '{{ value_json.Dimmer }}'
  brightness_scale: 100
  rgb: true
  {"POWER":"ON","Dimmer":3,"Color":"7,7,7,0","HSBColor":"0,0,3","Channel":[3,3,3,0]}
  rgb_state_topic: "stat/RGBliving1/RESULT"
  rgb_command_topic: "cmnd/RGBliving1/COLOR"
  rgb_command_template: "{{ '%02x%02x%02x00' | format(red, green, blue) }}"
  retain: true
  white_value: true
  white_value_command_topic: "cmnd/RGBliving1/channel4" # formato de 0-100
  {"POWER":"ON","Dimmer":100,"Color":"FF0000FF","HSBColor":"0,100,100","Channel":[100,0,0,100]}
  white_value_state_topic: "stat/RGBliving1/RESULT"
  white_value_scale: 100
  white_value_template: "{{ value_json.Channel[3] }}"
  availability_topic : "tele/RGBliving1/LWT"
  payload_available: "Online"
  payload_not_available: "Offline"

in this case , the power on command works , color works, brightness works, and white command works ,
but in all cases the command does NOT persists and an OFF command is received to power off the light .

I dont know what the reason is , but suspect of a problem with the status , and received status NOT matching the send command .

i also tried the autodiscovery , but the information receivbed from tasmota is incomplete in this case to properly configure the light . ( only the power , and brightness are configured) .
