Unusual Results with Light Component

ESPHome
1

I have been attempting to implement the Light Component on my daughters bedroom lights (A length of WS2812 under the bed).

There are two forms of triggering for the lights… a PIR sensor and a zigbee 3 button via MQTT. Everything seems fine, except the code occasionally spits an error related to the light effects.

Here’s my code…

And here’s the error I receive…

[10:11:35][D][main:927]: LED lights are ON with rainbow effect
[10:11:35][D][main:860]: The LED lights are ON Rainbow

No idea why I am seeing the… ‘FastLED WS2812B Light’ - No such effect ‘addressable_rainbow’ error? Especially when the random and pulse appear to work?

I am sure it’s something I am missing, and is probably something simple. Any feedback appreciated.

I notice you have all of them listed twice. No idea if this is the cause, (I know the docs show this, but I’ve always assumed it’s an error). I’ve always dropped the duplication and never had a problem.

Hey Ben,

Thanks for the reply. Yup, tried a number of combos of config in the ‘light’ code. Including removal of duplicate names etc.

Nothing seemed to make a difference. Almost seems like anything with ‘addressable’ has an issue.

Thanks for taking the time Ben, much appreciated.

So it turns out the fix is mind numbingly simple… instead of using addressable_rainbow you use rainbow when calling the effect from a script.

So the script looks like…

  - id: rainbow_effect
    then:
      - light.turn_on:
          id: bdrm_led_lights
          brightness: 70%
          effect: rainbow
      - logger.log: "LED lights are ON with rainbow effect"

Problem solved :yum:

Seems anything with addressable in the name must be removed for it to work.

EDIT… actually, it uses the name in the light yaml code.

- addressable_color_wipe:
          name: "Color Wipe Effect"
          colors:
            - red: 20%
              green: 70%
              blue: 25%
              num_leds: 5
            - red: 35%
              green: 15%
              blue: 60%
              num_leds: 10
          add_led_interval: 100ms
          reverse: false

So to activate addressable_color_wipe you use the following…

- id: color_wipe_effect
    then:
      - light.turn_on:
          id: bdrm_led_lights
          brightness: 70%
          effect: "Color Wipe Effect"
      - logger.log: "LED lights are ON with Color Wipe effect"
