The iopool Card is the main Lovelace card for the [hass-iopool](https://docs.page/mguyard/hass-iopool) integration. It brings together the most useful pool information from your iopool EcO sensor in a single dashboard view.

It can show temperature, pH, and ORP gauges, pump controls, filtration mode selection, boost controls, daily filtration progress, and a temperature history chart.

<Info>
  No separate installation is needed. The card is bundled with the hass-iopool integration and
  becomes available automatically once the integration is installed.
</Info>

## Light and dark themes

The card follows your Home Assistant theme automatically. There is nothing to enable and no
option to set: switch Home Assistant to a dark theme and the card follows on the next render.

It reads your theme's own colours rather than shipping a fixed light and a fixed dark palette,
so custom themes are handled too — the card picks up their card background and text colours
and derives its own surfaces from them.

<Info>
  The card follows the theme selected **in Home Assistant**, not your operating system's
  appearance setting. If Home Assistant is set to a light theme while your system is in dark
  mode, the card stays light — matching the rest of your dashboard.
</Info>

<Warning>
  The design is only guaranteed with the **default Home Assistant theme**, in both light and
  dark. That is the theme the card's colours are calibrated against and validated on.

  With a custom theme the card still adapts and stays readable, but the result may differ from
  the screenshots: tints shift with the theme's own background and text colours, and a theme
  that sets an unusual card background — a transparent or image-backed one, for instance — can
  visibly alter the gauges and inner panels. If a custom theme gives you an odd result, please
  compare with the default theme before opening an issue.
