Any possible way for showing a timer

[AlexanderGlogger]

I was wondering if it is possible to display a timer using EsphoMaTrix. E.g. a service is called in Home Assistant, which leads to an timer of specified duration (e.g. 5 minutes) being displayed on the matrix display.
Or are there any workarounds that would enable such functionality.

P.S. Thank you for developing this project.

Yes of course, but this does not belong in my component!

There are two ways:

• With automations from home assistant
• With lambdas in yaml

Both can use my component to display the time or delete the screen from the queue. The count down and the action on finish belongs to the lambda or automation. If i find the time i will try to create a yaml-solution, but it has no priority for me!

Thanks for the help and pointing me in the right direction. To clarify, I create a timer in an automation which then sends the new text to the display every second, right?

[lubeda]

yes, that should do the trick.

Hi,
i found a way. If you have an timer helper in home assistant e.g. timer.eier_timer you can uses this automation:

alias: Display Timer on ulanzi
description: ""
trigger:
  - platform: state
    entity_id:
      - timer.eier_timer
    to: active
condition:
  - condition: state
    entity_id: timer.eier_timer
    state: active
action:
  - service: esphome.ulanzi_add_screen
    data:
      alarm: false
      icon_name: timer
      screen_time: 10
      lifetime: 1
      text: >-
        {{ (state_attr('timer.eier_timer', 'finishes_at') | as_datetime -
        now()).total_seconds() | int(0) }}
  - service: esphome.ulanzi_force_icon_screen
    data:
      icon_name: timer
  - delay:
      hours: 0
      minutes: 0
      seconds: 1
      milliseconds: 0
  - service: automation.trigger
    data:
      skip_condition: false
    target:
      entity_id: automation.display_timer_on_ulanzi
mode: restart

You can optimize a lot of things in this automation but it works.
