Custom (light) components for ESPHome

RGB-CT Light

Create a real Philips HUE Lightstrip look-a-like with ESPHome and RGB+CT lightstrips.

• Allows mixing rgb leds for color temperature outside of range of the white leds.
• Same behaviour as native Hue lights in HA: RGB and white combiend into single light.
• Can be 100% color matched with other HUE lights.
• Also works with light bulbs

Installation:

1. Copy custom_components folder into esphome config directory (e.g. /config/esphome).
2. Use configuration from below.

Example ESpHome config:

light:
  - platform: rgbcct
    name: "${device_name}: RGBCCT Light"
    red: pwm_r
    green: pwm_g
    blue: pwm_b
    warm_white: pwm_ww
    cold_white: pwm_cw
    cold_white_color_temperature: 6500 K
    warm_white_color_temperature: 2400 K
    # In Kelvin or Mireds
    max_warm_color_temperature: 500 mireds  # Optional defaults to 500 mireds
    max_cold_color_temperature: 153 mireds  # Optional defaults to 153 mireds
    constant_brightness: false  # Optional defaults to false, make white brightness levels combine to max_combined_white_level
    max_combined_white_level: 1  # Optional defaults to 1, reduce if light is unable to support max brightness

output:
  - platform: esp8266_pwm
    pin: GPIO13
    id: pwm_ww

  - platform: esp8266_pwm
    pin: GPIO12
    id: pwm_g
    max_power: 45%

  - platform: esp8266_pwm
    pin: GPIO14
    id: pwm_b
    max_power: 30%

  - platform: esp8266_pwm
    pin: GPIO5
    id: pwm_cw
    
  - platform: esp8266_pwm
    pin: GPIO4
    id: pwm_r
    

In the example above replace the correct values for the GPIO pins. Adjust max_power setting for each channel to match your lightstrip. Above settings were tested using a (very common) 24V RGB-CT 5050 ledstrip from Amazon/Ali. Adjust the levels until the light exactly matches.

Adjust min/max color temperature of light as desired.
