Tuya ignores Brightness in automation

Question: I bought a wifi Tuya LED strip. After install, I can manage it in the Tuya app and can manage it with the Tuya integration in HA(Colorpicker in Developer tools)

It’s all working fine in HA core-2021.12.10. The problem is the automation.

I can only manage the LED strip with service light.turn_on and light.turn_off when I don’t set any attributes like brightness, RGBcollor, Transition, etc.
I can set attributes when I use the color picker in Developers Tools.
What can be wrong, or is there a workarround? (edited)

trigger:
  - platform: state
    entity_id: >-
      binary_sensor.zb_pir_slaapkamer_occupancy,
      binary_sensor.zb_pir_sk_beneden_marjan_occupancy
    to: 'on'
condition:
  - condition: and
    conditions:
      - condition: state
        entity_id: sun.sun
        state: below_horizon
      - condition: state
        entity_id: light.lamp_slaapkamer
        state: 'off'
action:
  - service: light.turn_on
    data: {}
    target:
      entity_id: light.smart_led_strip_rgbww_5_meter_ip65

If I add Brightness to the automation. the Led Strip won’t switch on/off anymore.

Who can help me?

For me, the brightness is not working at all, not just in automation.
When I change the slider, nothing happens. When I restart the strip it just turns on the previous brightness.

Brightness is working, but first I need to change the mode of the strip in the tuya app. After that everything was ok.

What mode did you change? All my tuya switch with brightness control are not working in HA
