LED Configuration

Use one of the following three configurations to adjust the led to your needs. Note: Using the Status LED on the 4CH Pro may cause relay 4 to activate on power up.

Status LED (see https://esphome.io/components/status_led.html)

status_led:
  pin:
    number: GPIO13
    inverted: True

Always-on led (plugged in == led on)

output:
  - platform: esp8266_pwm
    id: blue_led
    pin: GPIO13
    inverted: True


light:
  - platform: monochromatic
    name: "Blue LED"
    output: blue_led
    restore_mode: ALWAYS_ON
    internal: true

Normal light, toggleable via Home Assistant

output:
  - platform: esp8266_pwm
    id: blue_led
    pin: GPIO13
    inverted: True


light:
  - platform: monochromatic
