Ondilo ICO

ICO by Ondilo is a small connected device that you simply drop into the pool or spa. ICO continuously analyzes the water quality of your pool/spa and notifies you via its application. ICO provides personalized recommendations so that you use the right products in the right proportions at the right time.

There is currently support for the following information within Home Assistant:

  • Water Temperature
  • Oxydo Reduction Potential (ORP/Redox)
  • pH
  • TDS (Total Dissolved Solids) or Salt
  • Battery
  • RSSI

Sensors will be created for all those data.


Adding Ondilo ICO to your Home Assistant instance can be done via the user interface, by using this My button:
