About

Quatt is an unofficial integration for Quatt heat pumps and the Quatt Home Battery. It reads heat pump data locally from the CIC JSON API and adds sensors, climate controls, numbers, selects, switches, buttons, times and binary sensors. Optional features use the Quatt mobile API, which adds remote sensors, home battery support and chill support, and sign-in to the Quatt Energy portal is also available. Options cover the local and remote update intervals and an external power sensor for the Quatt's energy consumption. The mobile API features were reverse-engineered, so they may stop working if Quatt changes its API. Setup is done in the UI, and Home Assistant can discover the device on the network.
