Works with HACS Mushroom cards, card-mod, and Home Assistant YAML configurations.

Home Assistant Mushroom Cards

Build minimalist, mobile-first Home Assistant dashboards using the Mushroom cards design system.

Overview

Installation: HACS → Frontend → Search “Mushroom”

When to Use This Skill

Use this skill when you need to:

• Build minimalist, mobile-first Home Assistant dashboards with modern design
• Create compact status indicators with chips cards for quick information
• Use template cards with Jinja2 for dynamic content and conditional styling
• Style entity controls with card-mod for custom CSS and animations
• Implement full UI editor support without writing YAML
• Display specialized entity types (light, climate, media player, person) with optimized controls

Do NOT use when:

• You need complex multi-entity cards (use entities card instead)
• Building data-heavy dashboards with graphs and charts (use visualization cards)
• You prefer traditional Home Assistant card styling (use native cards)

Usage

Follow these steps to create Mushroom card dashboards:

1. Install Mushroom via HACS (Frontend category)
2. Select card type based on entity (entity, light, climate, chips)
3. Configure card using UI editor or YAML
4. Add styling with card-mod for custom CSS (optional)
5. Test on mobile for responsive design verification

Mushroom is a complete design system for Home Assistant featuring:

• 13+ specialized card types for entities, controls, and status display
• Minimalist Material Design aesthetic
• Full UI editor support (no YAML required)
• Mobile-first responsive design
• Card-mod integration for advanced styling

      border-radius: 15px;
    }

    }

Conditional Styling

type: custom:mushroom-entity-card

    :host {
      {% if states('sensor.temperature') | float > 25 %}
        --card-mod-icon-color: red;
      {% elif states('sensor.temperature') | float < 18 %}
        --card-mod-icon-color: blue;
      {% else %}
        --card-mod-icon-color: green;

    }

Grid Spanning

type: custom:mushroom-entity-card
entity: sensor.temperature
card_mod:
