MMM-KitchenTimer - Touch-friendly countdown timer

@Niggich sorry, this is case sensitive and I had lower case s, see my edit

[Niggich]

@sdetweil No, it’s not working. This is the automation

alias: MagicMirror kitchen timer started
triggers:
  - trigger: mqtt
    topic: magicmirror/kitchen-timer/started
actions:
  - action: media_player.play_media
    target:
      entity_id: media_player.echo_show_kuche
    data:
      media:
        media_content_id: >-
          set a timer for {{ trigger.payload.remainingSeconds | int }}
          seconds
        media_content_type: custom
        metadata: {}

@Niggich if you examine the traces , what error is reported?

@sdetweil sagte:

if you examine the traces , what error is reported?

This Error is shown: “Error rendering data template: UndefinedError: ‘str object’ has no attribute ‘remainingSeconds’”

When I change the trigger back to trigger.payload_json.remainingSeconds is no Error reported an the Echo asks for how long should be the timer.

The traces-Log says this.

params:
  domain: media_player
  service: play_media
  service_data:
    entity_id:
      - media_player.echo_show_kuche
    media_content_type: custom
    media_content_id: set a timer for 60 seconds
  target:
    entity_id:
      - media_player.echo_show_kuche
running_script: false

@Niggich ok. Good info

I need to test this myself, but won’t be able to til tomorrow sometime. I also need to use my echo device which is currently not used

[Niggich]

@sdetweil Ok, don’t worry. I’m happy you help me. Thank you!

EDIT:

I made a copy of the automation and put a custom number of seconds to trigger. The Echo still asks for how long. The I changed from seconds to minutes an the timer starts.

EDIT2: When I change the trigger to German language like this starte einen {{ trigger.payload_json.remainingSeconds | int }} sekunden timer the Timer starts. The only thing is that the Echo almost 4 seconds need to start the timer.

@Niggich awesome feedback

[Niggich]

@sdetweil Yeah that’s great. Do you an Idea for the delay between Mirror an Echo?

[sdetweil]

@Niggich you could subtract a fixed delay amount

Basic Subtraction Code
You can place this snippet inside a template condition, action, or template sensor. 
For more advanced examples, visit the official Home Assistant Templating Guide.jinja2{{ (states('sensor.first_number') | float(0)) - (states('sensor.second_number') | float(0)) }}

Use code with caution.
Important Rules for TemplatesStates are text:
 Home Assistant treats all sensor states as strings (words) by default. Adding | float forces it to act like a number.

Prevent errors with defaults: Use float(0) instead of just float. If your sensor goes offline or shows unavailable, the 0 acts as a safety net so your automation does not crash.

Use parentheses: Wrap each sensor and its filter in parentheses ( ) to ensure the math calculates in the correct order.

@sdetweil Sorry for the late answer. I was a bit busy. I will have a look to your Subtraction Code at the Weekend. Thanks
