It has 2.7k installs sharing analytics, works locally and was last updated October 25, 2026. 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. Automatic summary of the README and code of TypQxQ/Sigenergy-Local-Modbus.

No vendor cloud in between. - **Found by itself**: Home Assistant spots it on the network and offers to add it. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### Configure Sigenergy Plant - **Read-Only Mode**: (Prevents Home Assistant from making changes to the Sigenergy system. Recommended for initial setup. Can be changed later in device settings.) ### Select Device Type - **Device Type** ### Configure Sigenergy Plant - **Host (IP address of the main Sigenergy inverter)** - **Port (default is 502)** - **Inverter Device ID (Default is 1)** - **AC Charger Device IDs (comma-separated when multiple. Default is empty for no AC charger)** - **Inverter IDs with DC Chargers attached (comma-separated when multiple)** - **Scan Interval (seconds)** - **Migrate legacy YAML sensor values** - **If enabled, initial sensor values will be imported from the legacy YAML configuration (if present).** - **Read-Only Mode**: (Prevents Home Assistant from making changes to the Sigenergy system.
