Widget

Data

One entity, one big number. The Data widget reads a single Home Assistant entity and shows its current value as a large, styled readout — temperature, power, humidity, battery, a price, a count, anything with a state. Units are formatted and converted automatically.

What it does

The Data widget displays the live state of one entity as a single oversized value. Above it sits an optional label (the widget's name); below it, the value in a font size, weight, design, color, and alignment you choose. The text shrinks to fit if it gets long, so the number always stays on one line.

It reads, it doesn't control The Data widget is a pure readout — there's no tap action. For a tap-to-toggle tile use the Control widget; for a needle/arc use the Gauge; for history over time use the Graph.

Add it

Enter edit mode, tap Add Widget, choose Data.
Pick the entity whose value you want to show.
Open the widget's inspector (tap the widget while editing) to style the readout.

Settings

Setting	What it does
Value size	Point size of the big number. Ranges from 14 pt to 90 pt (default 30 pt).
Weight	Light, Regular, Medium, Semibold, or Bold. Default Semibold.
Font	Type design: Default, Rounded, Serif, or Mono. Default Rounded.
Align	Left, Center, or Right — positions both the label and the value within the tile. Default Left.
Value color	Color of the readout. Leave it default to follow the theme's primary text color.
Label	The name shown above the value comes from the universal Label → Position setting. Set Label to Off to hide the name entirely and show only the number.

Where the label text comes from If you've typed a custom title for the widget, that's the label. Otherwise Flux uses the entity's friendly name. With no resolved entity it falls back to the raw entity id.

Formatting & units

Flux formats the value for you based on the entity's state:

Numeric value with a unit — the number is rounded (whole numbers show no decimal; otherwise one decimal place) and the unit is appended, e.g. 21°C, 1450 W, 63 %.
Unit conversion — if your unit preference is Imperial or Metric, recognized units are converted on the fly: °C↔°F, m↔ft, km↔mi, kg↔lb, L↔gal, hPa↔psi, m/s↔mph, and many more. Set the preference to Match HA to show values exactly as Home Assistant reports them.
No unit — the raw state is shown with friendly formatting (underscores become spaces, words are capitalized for things like sensor states).
Unavailable / Unknown — shows "Unavailable" or "Unknown".
No entity — shows a dash (—) rather than a misleading zero.

Conversion only applies to known units Units Flux doesn't recognize pass through unchanged. A non-numeric state with a unit is shown as-is (e.g. idle W would never happen, but a custom string state keeps its text). Temperature conversion for climate/weather follows the unit Home Assistant reports.
