If it does not list an attribute like this:

effect_list: effect_colorloop

You are going to have to use a script or automation to do it.

How can I do it with script or automation, I am new to home assistant.

That’s a script. It needs to all be indented under script: or if you have split your configuration, put in your scripts.yaml file.

I placed them in correct locations, but am getting this error Unable to find service script.rainbow_light

Try the script like this:

rainbow_light:
  alias: rainbow light
  mode: single

  fields:
    entity:
      description: The entity that will be rainbowed
      example: light.bathroom

Thanks a lot, it’s working

One last thing, Is it possible make colors fade rather than hard change?

10

Increase the transistion time in this bit:

  sequence:
    - service: light.turn_on
      data_template:
        xy_color: |
          {{  colors[(now().second/2.5)|round(0)] }}
        transition: 1
        entity_id: '{{ entity }}'

Thanks, all good.

What are these color values [0.157,0.05] rgb?

12

It is xy_color.

13

Thanks,

Can’t thank you enough.

14

@tom_l Will the RGB values work instead of xy?

15

Yes you would just have to change the variables and the light.turn_on service call.

16

Is there a limit of how many color variables can be there?

17

No but there is a limit to the number of colours your lights can display. You might find that RGB values like [ 0, 248, 255] and [ 0, 255, 255] look so similar as to be indistinguishable.

Also I missed that this part of the template would need adjusting if you altered the transition time.

{{  colors[(now().second/2.5)|round(0)] }}

It would also need adjusting if you changed the number of colours. It only works with a transition time of 1 second and 25 colours. So if you have adjusted the transition time you are probably not seeing all the colours.

18

So 2.5 = 25 colors?

19

Including zero, yes.

The index for the list of colours starts counting at 0, so [0, 1, 2, 3 … 24]

60 sec / 2.5 = 24

As the transition cant be interrupted, if you use a transition time of 5 seconds you would only see 5 colours.

What transition time are you using?

20

Let’s say I want to use 100 colors, what would my setting for seconds and transition?
