E27 15W RGBCCT bulb ESPHome config

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

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.

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

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 😎

I'm a little late to the party, but found https://www.reddit.com/r/Esphome/comments/kscy9z/custom_light_component_need_c_advice_athom_15w/

I don't have one of the bulbs yet, going to have to wait until after Chinese New Years and they end up getting some more made, but definitely anxiously awaiting some!

@Martin Leonard the 7w has an esp8285 bord the 15w is 8266

Not working so well. At the blue end of the range, the light is completely off... the cw led's really never engage. At the lower ends of intensity, the bulb just turns off.

OTOH this works in Tasmota, it just doesn't control correctly from Home Assistant.

It's almost like I wasted a bit of $$ on these bulbs. I wanted to use them to get away from she-who-must-not-be-named (Al*xa), but in order to use them, I need to use Tasmota with Philips emulation and then control them with... Al*xa.

Not using Alexa so I can not comment on that or how it integrates with HA. I use HA with the nabu casa subscription for Google Home integration.

If Tasmota is functioning correctly for you, then the ESPHome config can likely be adjusted to work exactly the same in terms of capabilities. I had to make assumptions in my config, and acknowledge it isn't perfect.

Would be great if Athom would publish fully functional configs for ESPHome since the direct HA integration is a winning feature for me.

I'm so excited I found this! I've been trying to find a high lumen bulb that I could easily get to Tasmota/ESPHome! However, I can't seem to find this available for purchase at Tindie/Aliexpress :( Any idea of when it'll be back in stock anywhere for me to buy?

Mine is getting very hot.

@Andris Zarsss Well, at full brightness I can imagine it'd get hot. I don't necessarily need full brightness all the time, but the 700-800lm from most other bulbs just isn't enough sometimes, and I can just have it turned down except for the times I need the brightness.

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

Also, you have to remove the "White" value to zero in order to use the colour wheel.

Managed to upload a firmware, but HA is not offering any color changes, just on or off. Am i missing something?

In Lovelace, you need to make sure the bulb is on, and then click the three dots.
