Mushroom-climate-card, Showing additional information

I currently have something like this to sew my air conditioner status:

type: entities


entities:
  - type: custom:mushroom-climate-card
    entity: climate.master_zone
    hvac_modes: []
    icon_type: icon
    tap_action:
      action: more-info
    hold_action:
      action: none
    double_tap_action:
      action: toggle
    show_temperature_control: true
    collapsible_controls: false
    secondary_info: none
    layout: horizontal
    fill_container: true
    icon: mdi:fan
    primary_info: last-changed
title: Main Bedroom
header:
  type: picture

I wanted to show the status of the damper so I can see how much stuff is coming through

{{ states(‘sensor.master_zone_damper_open_percentage’) }}%

I tried to put it into secondary_info But I cannot see where that is displayed. How can I get this ideally into where the two hours ago indicator is?

I don’t believe the Mushroom Climate Card will accept template statements.

Here are a few methods

Less Complicated

type: custom:mushroom-climate-card
entity: climate.master_zone
hvac_modes: []
icon_type: icon
tap_action:
  action: more-info
hold_action:
  action: none
double_tap_action:
  action: toggle
show_temperature_control: true
collapsible_controls: false
secondary_info: none
layout: horizontal
fill_container: true
icon: mdi:fan
primary_info: none
card_mod:
  style:
    mushroom-shape-icon$: |
      .shape:after {  
        content: " {{states('sensor.master_zone_damper_open_percentage')}}% ";
        position: absolute;
        left: 50px;
        width: 35px;
        height:15px;
        background-color: transparent !important;
        font-size: 18px;
        color: white;
         }

More Complicated

type: custom:stack-in-card
mode: horizontal

        ha-card {
         left: -30px;
         border: none;
         background: none;}
         
  - type: custom:mushroom-template-card
    primary: |
      {{states('sensor.master_zone_damper_open_percentage')}}%    
    icon: ""
    card_mod:
      style: |
        ha-card {
          top: 10px;
          left: -80px;
          border: none;
          background: none;}

    card_mod:

        mushroom-state-item {
          display: none;
                 }
        ha-card {
           top: 10px;
           border: none;
           background: none;}
card_mod:
      style: |
        ha-card {
          border: 1px solid rgba(180,180,180 .3);}

Going forward I would post your Mushroom questions here or here
