Home Assistant integration for Sigenergy solar systems via the Cloud API
A Home Assistant automation shared as an example for Sigenergy energy controller owners in the Australian NEM who want to automatically maximise battery export during AEMO critical price events. It is posted here as a reference to adapt to your own system — not as a plug-and-play solution.
Adapter for Sigenergy solar energy systems via Modbus TCP/RTU
Home Assistant custom integration for Sigenergy Cloud
Autonomous battery arbitrage agent for AEMO NEM prices → Sigenergy inverter via Modbus. Built with Claude Opus 4.7 / Claude Code.
Autonomous Sigen inverter controller for home solar and battery systems. Very lightweight (can run on RPi), making mode decisions every 5 minutes based on solar forecasts and live battery SOC — optimising between, self-consumption, grid export, and overnight TOU charging. Using Irish ESB Solar forecasts but portable to other providers.
