E27 15W RGBCCT and EspHome, can't get CW to work

So basing my ESPHome (via Home-Assistant) configuration on this thread https://www.athom.tech/forum/light/e27-15w-rgbcct-bulb-esphome-config but no matter what, I can't get the Cool White LEDs to come on. I only get RGB and Warm White. I really don't understand it, the 7W config came together quick and easy.

My config is

substitutions:
  devicename: dining_light_1
  upper_devicename: Dining Light 1

esphome:
  name: $devicename
  platform: ESP8266
  board: esp01_1m

wifi:
  ssid: "<SSID>"
  password: "<PW>"

  ap:
    ssid: "${devicename} AP"
    password: "<PW>"

# Enable logging to ESPHome
logger:
  # Disable logging to serial
  baud_rate: 0

# Enable Home Assistant API
api:
  password: "<PW>"

# Setup OTA password
ota:
  password: "<PW>"
