Basic mode not supporting color temperature?

[Arakon]

I'm trying to get a zigbee control going for a RGB-WW-CW ceiling panel.
The current config will generate almost all attributes, but the color temp is missing.

esphomeconfig (1).txt

The result is:

I checked against a premade zigbee controller, and it seems to be missing this entry in the zigbee2mqtt definition:

zigbeelight.txt

Am I missing something in my config, or is this not supported yet?

[luar123]

Not implemented. I have not looked into color temp and have not seen a manual configuration that I could reuse.
Will keep this issue open until it is added.

Hi @Arakon,
you can get color temperature working already with the existing solution. You just need to define the endpoints and clusters manually (Advanced Mode). I’m using the following snippet, and it works correctly with zigbee2mqtt, including proper color temp support.

endpoints:
    - num: 1
      device_type: COLOR_DIMMABLE_LIGHT
      clusters:
        - id: ON_OFF
          attributes:
            - attribute_id: 0
              type: bool
              on_value:
                then:
                  - light.control:
                      id: tuya_light
                      state: !lambda "return (bool)x;"
        - id: LEVEL_CONTROL
          attributes:
            - attribute_id: 0
              type: U8
              on_value:
                then:
                  - light.control:
                      id: tuya_light
                      brightness: !lambda "return ((float)x)/255;"
        - id: COLOR_CONTROL
          attributes:
            - attribute_id: 0x400a # ColorCapabilities
              type: U16
              value: 0b0000000000010000 # Color temperature supported
            - attribute_id: 0x400b # ColorTempPhysicalMinMireds
              type: U16
              value: 153
            - attribute_id: 0x400c # ColorTempPhysicalMaxMireds
              type: U16
              value: 370
            - attribute_id: 0x0008 # ColorMode 
              type: U8
              value: 0x02 # ColorTemperatureMireds
            - attribute_id: 0x4001 # EnhancedColorMode
              type: U8
              value: 0x02 # ColorTemperatureMireds
            - attribute_id: 0x0007 # ColorTemperatureMireds
              type: U16
              device: tuya_color_temperature_sensor
              scale: 0.333
              on_value:
                then:
                  - light.control:
                      id: tuya_light
                      color_temperature: !lambda "return (float)x;"

It should generate a configuration similar to the one below

@BjornOne
Sorry, I only just got around to trying this. However, I'm not well versed in esphome and keep running into errors trying to build the firmware.
Mainly: " Couldn't find ID 'tuya_color_temperature_sensor'. Please check you have defined an ID with that name in your configuration." .

Could you please show me the full sketch needed, or how to define the color sensor? I checked the documentation but had no luck defining it.

I think this example is what you want: #80 (comment)

Just remove all the effect, scripts, on custom commant, and on identify parts (not supported yet )

Thanks for the info... I just got it figured out. Here's my script for the purpose:

Oh I thought you wanted RGB+CT
