# Ondilo ICO

> Ondilo ICO is a built-in integration for Home Assistant. It has 511 installs sharing analytics and needs the vendor's cloud.

Ondilo ICO is a built-in integration that reads pool water data from Ondilo ICO devices through the vendor's cloud. It adds sensors to Home Assistant, including oxydo reduction potential, RSSI, salt and TDS. Because the integration relies on the vendor's cloud, an internet connection is needed for the data to arrive. Setup is done in the user interface, where application credentials are chosen and sign-in happens on the vendor's own page. Nothing extra has to be installed, since it ships with Home Assistant.
