Horizontal individual allergy index (IAI) card with background

Who it’s for

Allergy sufferers, public health managers, and outdoor event organizers ask “can I see the allergy risk status across all monitoring locations at once, in a compact layout where the risk is immediately obvious?” The horizontal background variant combines the space efficiency of the horizontal layout with full-card color coding.

What it does

A sensor reporting IAI_level = 4.1 displays the index in a wide, low-height card whose entire background fills with the risk color: green for Good (0–2), light green for Moderate (2–6), orange for Elevated (6–9), and red for Hazardous (above 9).

• Full-card background color in a compact horizontal format makes allergy risk obvious without reading the number
• Live IAI reading
• Shows one sensor’s reading per widget; stack multiple widgets to cover an entire network of locations in a narrow column

How to set up

Data keys

Key	Role	Type	Description
IAI_level	Main value	Timeseries	Individual Allergy Index value (unitless); change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled IAI, so it draws random values until you point the datasource at a device and rename the key.

To point it at your own device: open the dashboard in edit mode, open the widget’s Datasources, pick the entity or entity alias, and replace the function key with the key your device reports.

Value ranges

Range	Level	Color
0–2	Good	Green
2–6	Moderate	Light Green
6–9	Elevated	Orange
9+	Hazardous	Red

How to customize

• To change the severity thresholds — edit Icon color ranges and Value color ranges; set the same boundaries in both so the icon and the number always agree.
• To change the band colors — edit the color of each range in Icon color ranges and Value color ranges.
• To add a units label — set a custom Units label in the widget settings to indicate the index scale to end users.

Tips

• A column of horizontal IAI cards with colored backgrounds on a public information display lets visitors instantly assess which parks or venues have elevated allergen risk before heading outside.
• Use consistent severity colors across all allergy and air quality widgets.
• Pair this layout with IAI chart cards to give health managers a trend view for any elevated location.
