About

Sigenergy ESS monitors and controls a Sigenergy Energy Storage System from Home Assistant over local Modbus-TCP. It groups plants, inverters, AC chargers and DC chargers as devices, and Home Assistant can discover inverters and chargers on the network. Sensors cover power flows, energy statistics and battery state of charge and health, with an adjustable update interval. Energy management work modes are exposed as select entities, and optional buttons, switches and numbers provide further control. A read-only mode stops Home Assistant from making changes to the system, and it can be changed later in device settings. Setup is done in the UI, and devices can be reconfigured, added or removed afterwards.
