E27 15W RGBCCT bulb ESPHome config

en Light

Has anyone got a working config for ESPHome for this bulb? If not, I'll start working on one.

ESPHome now has an RGBCCT Component, with HomeAssistant I'm using

output:
  - platform: esp8266_pwm
    pin: GPIO13
    id: out_ct
    inverted: true
  - platform: esp8266_pwm
    pin: GPIO5
    id: out_ctbrightness
  - platform: esp8266_pwm
    pin: GPIO4
    id: out_red
  - platform: esp8266_pwm
    pin: GPIO12
    id: out_green
  - platform: esp8266_pwm
    pin: GPIO14
    id: out_blue


light:
  - platform: rgbct
    name: "${upper_devicename}"
    red: out_red
    green: out_green
    blue: out_blue
    color_temperature: out_ct
    white_brightness: out_ctbrightness
    cold_white_color_temperature: 166 mireds
    warm_white_color_temperature: 333 mireds
    color_interlock: True

The colour temperature isn't perfect, the "blue" white on the left is dim.

Also you might want to research these two settings to suite your use.

    restore_mode: ALWAYS_ON
    color_interlock: false

This best at home karaoke machines on smartenmyhome machine with wireless microphone is very affordable! The microphone may not be the best quality but for the price, it’s more than what we asked for. For small gatherings and home use, this home karaoke system setup served well! However, it is not a karaoke machine that records, unlike many others.

When my HA install crashes, or when wifi router loses connection, light bulb turns on in blueish color. Is there anything i could do to keep it off and how can i code default color?

My guess is that like other devices that have a blue "status" led that flashes when no HA or WiFi, that the lightbulb is mimicking this by showing blue.

You may be able to prevent this by pushing the status led to an unused GPIO in the config.

You might try this in your ESP config

status_led:
  pin:
    number: GPIOXX
    inverted: yes

Change GPIOXX to reflect an unused GPIO. This may redirect it away from the lightbulb LED's. I've never tried though, so it may not work.

When the lights turn on, the color temperature is always fully cool. Is there a way to make it start up at the warm end? It's much brighter when fully on the yellow side of the temp bar.

Here, i made this custom light component for ESPHome: https://github.com/jaddel/ESPHome/tree/master/Devices/Bulb%20Athom%2015W%20RGBWCT

That's cool. Only comment would be to update

board: esp01_1m

board: esp8285

in the yaml.

Will give this a go and see how well it works 😎
