Sensors

A sensor card displays a live reading from a Home Assistant sensor entity. It shows a large value with an optional unit and a label underneath — useful for temperatures, humidity, power usage, or any numeric sensor.

Sensor cards are read-only — tapping them does nothing.

Setting up a sensor card

1. Select a card and change its type to Sensor.
2. Enter a Sensor Entity — the Home Assistant entity ID of the sensor you want to display (for example, sensor.living_room_temperature).
3. Set a Unit — the unit label shown next to the value (for example, °C, %, W, or kWh).
4. Set a Label (optional) — shown below the value. If left blank, the entity ID is used.
5. Set Unit precision (optional) — choose how many decimal places to show. Options are 10 (whole number, the default), 10.2 (one decimal place), or 10.21 (two decimal places).

How it works on the panel

• The card displays the sensor's current value in large text, with the unit beside it and the label underneath.
• The value updates in real time as Home Assistant reports new readings.
• By default, numeric values are rounded to a whole number. Use the Unit precision setting to show one or two decimal places instead.
• The card uses the tertiary colour (configurable in Appearance) as its background, so sensor cards are visually distinct from toggles and buttons.
