About

Mixergy is an integration that connects Mixergy's smart water tank to Home Assistant. It reports the temperatures at the top and bottom of the tank, the current charge, the state of the heating and the energy used by the direct heating element. Further sensors flag low charge and no charge. It also provides numbers, sensors and switches, and services to boost the charge, set the target temperature, set or clear holiday dates and change the default heat source. It relies on the vendor's cloud, and setup in the UI asks for a username, password and the tank's serial number.

From the README

Add support for Mixergy's smart water tank into Home Assistant. This integration will return the current temperatures at the the top and bottom of the tank, the tank's current charge, the state of the heating and the energy used by the direct heating element. It also has sensors to report low charge (< 5%) and no change (0%).
