Mushroom template card, show sensor value in secondary information

Configuration Frontend
1

I’m sure this is doable, I’ve created a template card that toggles the state of a blind. What I’d like is the secondary information to be the battery level of the blind, which is exposed through sensor.landing_blind_battery
Is there a tutorial somewhere for this kind of data inserts into cards?

There is a big Topic in this forum for mushroom cards, and tons with templates, as a new user here you should read the first Topic
How to help us help you - or How to ask a good question.

And then use the search function in top right corner ( I.E mushroom template card ) , tons of examples in here

You could do something like this without the template:

type: custom:mushroom-cover-card
entity: cover.curtain_3ff5
show_buttons_control: true
show_position_control: true
show_tilt_position_control: true
primary_info: name
fill_container: true
name: Blinds
card_mod:
  style: |
    ha-card:after {
      content: "{{ states('sensor.basement_sensor_battery') }}%";
      position: absolute;
      display: flex;
      align-items: center;
      top: 34px;
      left: 110px;
      width: 16px;
      height: 16px;
      font-size: 11px; 
      color: lime
    }

or I’d suggest stacking cards

type: custom:stack-in-card
cards:
  - type: custom:mushroom-template-card
    entity: update.home_assistant_supervisor_update
    icon: mdi:window-shutter
    icon_color: blue
    primary: Blinds
    secondary: |
      {{states('cover.curtain_3ff5') }} 
      {{states('sensor.basement_sensor_battery') }} %
    card_mod:
      style: |
        ha-card {
          padding-bottom: 10px !important;
        }
  - type: custom:mushroom-cover-card
    entity: cover.curtain_3ff5
    show_buttons_control: true
    show_position_control: true
    card_mod:
      style: |
        mushroom-state-item {
          display: none;
        }
card_mod:
      style: |
        ha-card {
        box-shadow: none;
        --ha-card-border-width: 0px;
                         }
