Spinner

Description

The spinner component is used to display and set a numerical value within a defined range of numbers, similar to the Slider. A classic use case would be setting a target temperature. The current value is displayed in the middle and there are two buttons on the left and right to increase or decrease the value by the set step width.

<cv-spinner format="%.1f °C" min="15" max="25" step-width="0.5">
    <cv-address transform="DPT:9.001" mode="read">1/4/1</cv-address>
    <cv-address transform="DPT:9.001" mode="write">1/4/2</cv-address>
    <label class="value primary"/>
</cv-spinner>

The value range is limited by the attributes min and max. The step width can be set with the attribute step-width.
