Indoor humidity card with background

Who it’s for

Facility managers, HVAC engineers, and building managers ask “can I see the humidity status for every monitored zone at a glance, without reading individual numbers?” The background-color variant is designed for building management dashboards where a single colored card must communicate comfort status from across a control room.

What it does

A sensor reporting humidity = 45% displays the reading on a card whose entire background fills with the comfort color: orange for Low (0–30%), green for Comfortable (30–60%), and red for High (above 60%).

• Full-card background color makes humidity status readable across a room without reading the number
• Live humidity reading in %
• Shows one sensor’s reading per widget; tile multiple widgets to monitor all zones at a glance

How to set up

Data keys

Key	Role	Type	Description
humidity	Main value	Timeseries	Relative humidity in %; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Humidity, 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
0–30	Low	Orange
30–60	Comfortable	Green
60+	High	Red

How to customize

• To change the comfort 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 background colors — edit the background color for each comfort level in the widget settings.
• To rename the units label — change the Units field in the widget settings if needed.

Tips

• On a facilities management display showing one card per floor or zone, the background color lets the duty manager spot a problem area instantly without scanning individual humidity values.
• Use consistent comfort colors across all indoor environment widgets: green is comfortable, orange or red needs attention.
• Pair this card with a temperature card on the same row so operators can see both parameters simultaneously and identify whether discomfort complaints are driven by humidity, temperature, or a combination of both.
