Trying to automate a light to turn off only if it's a set percentage (40%)

Configuration
1

So I think there may be two solutions to this issue. I first have an automation that will turn on a lightstrip to 40% brightness & colour temperature of ~2500K when motion is detected as long as the lightstrip was already off to begin with (that way if it’s already on, then it’s not going to dim or change off the existing colour) this is working for me without any problems.

I would like an automation to turn this lightstrip off, under the following conditions:
-there has been no motion in the past 2 mins
-as long as the lightstrip is currently 40% brightness

OR

Turn off my first automation once no motion detected after 2 mins.

I used to have this configured this way via SmartThings without much of a hassle, but I’m trying to move everything over to HA. I’ve spent the last 3 hours trying to get HA to recognise the brightness of the lightstrip but it just won’t play ball and I’m completely clueless.

Here’s the current YAML for the automation I’ve currently got:

alias: Kitchen Motion night {ON}
description: >-
  Runs when kitchen motion sensor detects motion at night time, as long as
  kitchen lightstrip is currently off

  - condition: state
    entity_id: light.kitchen_island_lightstrip

    state: 40

    target:
      entity_id: light.kitchen_island_lightstrip

This doesn’t work unfortunately. The lightstrip still remains on after 2 mins.

When I press ‘Test’ on the condition, it comes back with “Condition did not pass”

Oh hang on. The brightness attribute is 0 to 255.

condition:
  - condition: state
    entity_id: light.kitchen_island_lightstrip
    attribute: brightness
    state: 102 # 40% of 255
5

Or to be safe:

condition:
  - condition: numeric_state
    entity_id: light.kitchen_island_lightstrip
    attribute: brightness
    below: 104 # 41% of 255
    above: 99 # 39% of 255

Brilliant, this worked! Thanks so much for your help and prompt responses. I actually got similar code using the visual editor but never got it working properly, so damn annoying haha!

I also tried the other one where you set it between 99 & 104 and that also works, but I’d rather have the exact amount since the % is always going to be exactly 40% as it’s set by automation every time.

I also tried using ChatGPT and it would always get syntax wrong or provide incorrect answers

Have a great day :smiley:

Yeah I’ve seen the gibberish config it writes.
