Indoor horizontal humidity card with background

Who it’s for

Facility managers, HVAC engineers, and building managers ask “can I monitor humidity across many rooms in a compact layout where the comfort status is still instantly visible?” The horizontal background variant combines space efficiency with the full-card color signal.

What it does

A sensor reporting humidity = 45% displays the reading in a horizontal 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 comfort status readable across a room without reading the number
• Horizontal layout fits more rooms per row on a multi-zone indoor environment dashboard
• Shows one sensor’s reading per widget; tile multiple widgets to monitor all rooms 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

• A row of horizontal background cards, one per room, lets the facilities manager see which spaces have out-of-range humidity after a weekend of reduced HVAC operation.
• Use consistent comfort colors across all indoor environment widgets: green is comfortable, orange or red needs attention.
• For archives, museums, or server rooms where humidity tolerances are tight, the colored background provides an immediate alarm-level signal that a plain numeric card does not.
