hi all

i stole a flow from here some time ago that gets all lights that are on and turns them off

i'd love to use this to auto change my lights brightness when my home mode goes from day to evening.

Here's what i'm trying which is giving error, i'm sure it's an easy fix but i'm not sure how to do it in the node "evening mode brightness"

thank you

I see you are using Home Assistant. You would be better sered asking about this on their forum.

Also I fixed your pasted code. In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````

You can edit and correct your post by clicking the pencil ✏ icon.
