ESPHome/MQTT CWWW light color_temp attribute missing?

I configured this CWWW light in esphome:

  - platform: cwww
    name: "${node_friendly_name}"
    cold_white: pwm_w
    warm_white: pwm_ww
    cold_white_color_temperature: 6500 K
    warm_white_color_temperature: 4566 K
    restore_mode: RESTORE_DEFAULT_ON

I’m using MQTT for my eshpome nodes, thus in HA the light is recognized by the MQTT integration.

Recently I noticed that I can set the color temperature for this light in the UI and in scripts/automations but the light entity doesn’t seem to have a color_temp attribute. Thus I can’t determine the current color temp value, neither in a template, nor in the UI, where I can use a color temp slider for this light but with the current value missing:

Why isn’t HA showing the current color temperature of this light, despite recognizing it as a CW/WW light entity? Is there anything I need to add either to the esphome config for this light, or some customization config in HA?

I believe this will be fixed in 2023.4.

No, I can’t see any difference, the current color temp value is still not shown with 2023.4.2. :man_shrugging:t2:
