Indoor temperature card with background

Who it’s for

Facility managers, building managers, and smart home owners ask “can I see the temperature status for every monitored space at a glance, without reading individual numbers?” The background-color variant is designed for control room displays where a single colored card must communicate thermal comfort from across the room.

What it does

A sensor reporting temperature = 21°C displays the reading on a card whose entire background fills with the comfort color: blue for Cold (below 18°C), light green for Comfortable (18–24°C), and red for Hot (above 24°C).

• Full-card background color makes temperature comfort level readable across a room without reading the number
• Live temperature reading in °C
• Shows one sensor’s reading per widget; tile multiple widgets to monitor all spaces at a glance

How to set up

Data keys

Key	Role	Type	Description
temperature	Main value	Timeseries	Indoor temperature in °C; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Temperature, 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 (°C)	Level	Color
0–18	Cold	Blue
18–24	Comfortable	Green
24+	Hot	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 switch units to °F — change the Units field and adjust the thresholds accordingly in the widget settings.

Tips

• On a facilities management display with one card per floor or zone, the background color lets the duty manager spot a heating or cooling failure immediately — a block of blue cards on a cold morning reveals which AHU is not running.
• Use consistent comfort colors across all temperature widgets: green is comfortable, blue needs heating, red needs cooling.
• Pair this card with a humidity card in the same grid so operators can assess both components of thermal comfort without switching views.
