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 at multiple locations across the network without reading individual numbers?” The background-color variant turns each card into a color signal that communicates risk level at a glance on a city-wide or campus monitoring dashboard.

What it does

A sensor reporting IAI_level = 4.1 displays the index on a 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 makes allergy risk readable across a room without reading the number
• Live IAI reading
• Shows one sensor’s reading per widget; tile multiple widgets to cover an entire monitoring network at a glance

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

• On a public information display, the background color instantly communicates allergy risk to passersby who may not read the numeric value.
• Use consistent severity colors across all air quality and allergy index widgets on the same dashboard.
• Pair this card with an IAI chart card so health managers can review the trend alongside the current status.
