        cards:
          # Temperature and humidity
          - type: horizontal-stack
            cards:
              - type: entity
                entity: sensor.shelly_wall_display_temperature
                name: Temp
              - type: entity
                entity: sensor.shelly_wall_display_humidity
                name: Humidity

          # Quick buttons
          - type: horizontal-stack
            cards:
              - type: button
                entity: light.living_room

Other URL parameters:

?hide_header - Hide only header
?hide_sidebar - Hide only sidebar

🌡️ Use Sensors in Automations

Example: Turn on Ventilation at High Humidity

automation:
  - alias: "Turn on ventilation at high humidity"
    trigger:
      - platform: numeric_state
        entity_id: sensor.shelly_wall_display_humidity
        above: 65
        for:
          minutes: 5
    action:
      - service: switch.turn_on
        entity_id: switch.ventilation

Example: Night Lighting Based on Light Level

automation:
  - alias: "Dim light in evening"
    trigger:
      - platform: numeric_state
        entity_id: sensor.shelly_wall_display_illuminance
        below: 50
    condition:
      - condition: time
        after: "18:00:00"
        before: "23:00:00"
    action:
      - service: light.turn_on
        entity_id: light.living_room_accent

📐 Optimal Dashboard Design

Tips for dashboards that work well on the 480x480 screen:

Recommendation	Why
Use large buttons	Easier to tap with finger
Max 6-8 elements	Screen is small
Avoid scrolling	Works poorly on device
Use icons	More intuitive than text
High contrast	Better readability
