# Ondilo ICO Pool V2 Essential+

*Ondilo*

> The Ondilo ICO Pool V2 Essential+ is a floating analyzer that measures pH, ORP and water temperature every hour in a pool, and adds TDS on the salt version. It connects over 2.4 GHz Wi-Fi and Bluetooth LE to the Ondilo app, and Ondilo lists Home Assistant plugins and an Alexa skill. Ondilo says Google Home and HomeKit are not yet supported. It suits Alexa and Home Assistant users through an integration (the maker's cloud). It does not support HomeKit and Google Home.
