⚠️ LEGACY PROJECT: This repository is superseded by the new HACS-based Sigenergy-Local-Modbus integration. No new features will be added here. See Discussion #98.
An easy-to-use YAML-based integration for Sigenergy inverters, battery and DC charger for Home Assistant.
This integration allows you to monitor sensor data and manage the EMS (Energy Management System) for Sigenergy inverters and batteries via Modbus TCP.
Note: Due to the limitations inherent in YAML-based Modbus configurations within Home Assistant, direct control of Sigenergy AC and DC Chargers is not supported in this version.
A new Python-based version, installable through HACS, is available at https://github.com/TypQxQ/Sigenergy-Local-Modbus.
The new version provides easier setup, updates, comprehensive support, including AC/DC Chargers and setups with multiple inverters.
The documentation covers following topics:
Wiki: FAQ, Troubleshooting, Known Issues
If you any kind of assistance, you have two options:

I have a Sigenergy SigenStor EC 15.0 TP Inverter and 4 8kWh batteries updating frequently to the latest version of Home Assistant (> 2025.4).
The Modbus register mapping is based on two documents I found online. I am not sure if I am allowed to share the files, but you can search for them using their names. If there are newer versions available, ket me know vis GitHub discussions.
