About
Sessy is an integration for the Sessy Smart Energy Storage System that communicates with the devices locally. It supports the Sessy Dongle battery, the P1 Meter and the CT Meter, and Home Assistant can find them on the network by itself. It adds battery status and charge or discharge sensors, meter readings for voltage, current and power, and a Wifi signal sensor. A select entity sets the power strategy and a number entity sets the power setpoint, while further controls change minimum and maximum power and start and stop times. It also covers a dynamic mode schedule per hour, EPEX energy prices, firmware updates and energy meters for the Energy Dashboard. Setup is done in the UI with the local username, password and host, and a scan interval can be changed in the options.
