Tasmota 4 Channel White LED configuration in Home Assistant

Hello,

I installed 4 normal white LED lights to a ESP8266 and I want to dimm them
independently of each other. I configured them in Tasmota as PWM 1-4. However, tasmota thinks I want to configure these LED’s as a LED Strip (with color etc.). I’m able to control the dimm state via Channel1-4 0-100 in the Tasmota console. However, I don’t know how to configure Home Assistant to control the lights independently from each other.

  - platform: mqtt
    name: "TV Wall Light 1"
    command_topic: "cmnd/light1/POWER"
    state_topic: "tele/light1/STATE"
    state_value_template: "{{value_json.POWER}}"
    availability_topic: "tele/light1/LWT"
    brightness_command_topic: "cmnd/light1/Dimmer"
    brightness_state_topic: "tele/light1/STATE"
    brightness_scale: 100
    on_command_type: "first"
    brightness_value_template: "{{value_json.Channel[1]}}"
    payload_on: "ON"
    payload_off: "OFF"
    payload_available: "Online"
    payload_not_available: "Offline"
    qos: 1
    retain: false

This works but dimming one light in HA dimms all lights.

Thanks
Kind regards
Chris
