You could use a https://www.home-assistant.io/integrations/timer/

  1. Push the button: Set the light to 5% and start the timer
  2. When the timer expires, turn off the light

You could also use a delay:

  1. Push the button: Set the light to 5%, delay X minutes, turn off the light

yes, i know how to create a timer , but i don’t know how to use on dash board with dimming :frowning:

this start the timer but how can i link the light and diming?

type: custom:mushroom-entity-card
tap_action:
  action: call-service
  service: timer.start
  target:
    entity_id: timer.timer
hold_action:
  action: more-info
double_tap_action:
  action: none
entity: timer.timer

  • When the timer starts, it sets the light’s brightness to 5%.
  • When the timer finishes, it sets the light’s brightness to 0%.
alias: example 
trigger:
  - id: '5'
    platform: event
    event_type: timer.started
    event_data:
      entity_id: timer.your_timer
  - id: '0'
    platform: event
    event_type: timer.finished
    event_data:
      entity_id: timer.your_timer
action:
  - service: light.turn_on
    target:
      entity_id: light.your_light
    data:
      brightness_pct: "{{ trigger.id }}"

EDIT

Correction. Wrapped id values in quotes to ensure they are interpreted as strings.

Thank you @123 but can you explain now where to put this code, i know how to create helpers automation from UI and edit buttons from dashboard but this it’s new to me, as you can see i’m at newbie level.

  1. In the Automation Editor, create a new, blank automation.
  2. Switch to YAML mode (available in the overflow menu, three vertical dots, in the upper right hand corner).
  3. Delete whatever may already be displayed in the editor.
  4. Copy-paste the example I posted above into the editor.
  5. Save the automation.
  6. Switch back to Visual mode and make whatever changes you may require (such as setting the correct entity_ids for your timer and light).

Change this:

  - id: 5

to this:

  - id: '5'

Change this:

  - id: 0

to this:

  - id: '0'

Then save the automation let me know if there are any other error messages.

The two id values are used to set the light’s brightness level.

  • When the timer starts, the first Event Trigger is triggered and its id value is used to set the light’s brightness to 5%.
  • When the timer finishes, the second Event Trigger is triggered and its id value is used to set the light’s brightness to 0% (in other words, it turns off the light).
