[Minor][Feature Request]: Support for Split-Cavity Oven Monitoring

[Breizh3122]

Hello!

Since I discovered your card and functionality, I'm progressively migrating the information components of my main dashboard from custom:button-card to your alert card.

I'm currently working on my oven appliance and despite my research I cannot find any card to my taste except your card.

I have a connected Oven that can be split into two different cavities, processing different actions at different temperatures for different periods of time. I need a card that can monitor these 3-4 entities (Action, Temp, SetPoint, Time) for both cavities, at least 3.

Do you have any plans to create a similar card for monitoring purposes, or is this something planned to be integrated into the current card?

PS: The card visibility is not an issue for me; I plan to integrate your card inside a custom:button-card container and use the hidden option which can be templated.

Thanks!

Hi @Breizh3122 — great use case, thanks for the detailed description!

The card currently rotates one alert slide at a time, so showing both cavities simultaneously isn't possible out of the box. That said, you can get a pretty useful result right now using Jinja2 templates to pack all four values into a single slide per cavity:

alerts:
  - name: "Upper cavity"
    entity: sensor.oven_upper_action
    theme: info
    message: "🔼 Upper — {{ states('sensor.oven_upper_action') }}"
    secondary_text: >
      {{ states('sensor.oven_upper_temp') }}° /
      {{ states('sensor.oven_upper_setpoint') }}° set —
      {{ states('sensor.oven_upper_time') }} remaining
  - name: "Lower cavity"
    entity: sensor.oven_lower_action
    theme: info
    message: "🔽 Lower — {{ states('sensor.oven_lower_action') }}"
    secondary_text: >
      {{ states('sensor.oven_lower_temp') }}° /
      {{ states('sensor.oven_lower_setpoint') }}° set —
      {{ states('sensor.oven_lower_time') }} remaining

The two slides alternate in the ticker. Not ideal for a real-time side-by-side view, but it covers the monitoring use case without any changes.

For a future release I'm planning a static_display mode that would stack multiple slides vertically inside the card at the same time — which would solve your use case perfectly and benefit other multi-zone monitoring scenarios too (HVAC zones, battery banks, etc.). I'll keep this issue open to track it.

Thank you for the quick answer!

Regarding the static_display mode, while it sounds like a great feature for other use cases (like HVAC or batteries), it actually isn't necessary for my oven setup. I prefer the card to only be visible when the oven is active, which is why I’m currently using the hidden logic in the parent custom:button-card container.

I hope seeing this implementation is helpful for your future development! I also discovered that the Nuclear theme is the ideal choice for this—the spinning nuclear icon looks exactly like a spinning oven fan, and the orange color perfectly symbolizes the heat. (Not to mention, the "Nuclear" theme is quite well-aligned with my personal cooking skills! 😂)

I plan to do some more design testing in the coming days to see how this layout holds up. Here is the code I am currently using to manage the dual-cavity layout:

Upper Cavity:

type: custom:button-card
template: container
color: "#eb8e0dde"
name: |
  [[[ 
    return states['binary_sensor.oven_second_cavity_status'].state === 'on' ? 'Upper Oven' : 'Oven';
  ]]]
hidden: |
  [[[ 
    return ['inactive', 'off', 'none', 'ready'].includes(states['sensor.oven_job_state'].state);
  ]]]
custom_fields:
  buttons:
    card:
      type: custom:alert-ticker-card
      cycle_interval: 5
      show_when_clear: false
      clear_message: ""
      clear_theme: success
      alerts:
        - entity: sensor.oven_job_state
          operator: "="
          state: "on"
          message: Oven Job state
          secondary_text: >
            Set {{states('sensor.oven_setpoint') }}° C — Temp {{ 
            states('sensor.oven_temperature') }}° C/ Remaining Time: {{    
            states('sensor.oven_completion_time') }}
          priority: 1
          theme: nuclear
          icon: ☢️
      cycle_animation: bounce

Bottom Cavity:

type: custom:button-card
template: container
color: "#eb8e0dde"
name: Four Bas
hidden: |
  [[[ 
    const dualMode = states['binary_sensor.oven_second_cavity_status'].state === 'on';
    const running = !['inactive', 'off', 'none', 'ready'].includes(states['sensor.oven_second_cavity_job_state'].state);
    return !(dualMode && running);
  ]]]
custom_fields:
  buttons:
    card:
      type: custom:alert-ticker-card
      cycle_interval: 5
      show_when_clear: false
      clear_message: ""
      clear_theme: success
      alerts:
        - entity: sensor.oven_second_cavity_job_state
          operator: "="
          state: "on"
          message: Oven Job state
          secondary_text: >
            Set {{states('sensor.oven_second_cavity_setpoint') }}° C — Temp {{ 
            states('sensor.oven_second_cavity_temperature') }}° C/ Remaining
            time : {{     states('sensor.oven_second_cavity_completion_time')
            }}
          priority: 1
          theme: nuclear
          icon: ☢️
      cycle_animation: bounce

I am now exploring how to use your card for my washing machine as well.

Thanks again for your time and for this awesome card! 👍
