- Control buttons, watch the temperature and get current states from your browser.
- Custom text on the SPA pump display.
- Custom sound instead of just beeping is possible.

- Simple to build. No hardware changes needed on the SPA pump. Just remove the display, disconnect the 6- or 4-pin ribbon cable and plug it into this device.
