This repository contains the configuration and logic for integrating a "SG Ready" heat pump controller into a Home Assistant environment. It enables smart control of heating and hot water systems based on energy availability, solar production, and dynamic tariffs.
-
SG Ready State Management
Supports all four SG Ready operating modes (1–4) with configurable timeouts and triggers. -
Home Assistant Integration
YAML-based configuration for ESPHome and Home Assistant automations. -
Energy-Aware Control
Optimizes heat pump operation based on solar production, battery state, and grid consumption. -
Monitoring & Logging
Real-time status via Home Assistant dashboard, including COP, energy consumption, and activation history. -
Failsafe & Manual Override
Includes timeout logic and manual control options for each SG Ready state.
- Home Assistant (tested with 2025.8.x)
- ESPHome (compatible with ESP8266/ESP32)
- SG Ready-compatible heat pump (e.g. Stiebel Eltron ISG)
- Energy monitoring setup (e.g. SolarWatt, SMA, InfluxDB)
- Flash the ESPHome YAML to your microcontroller
- Import the Home Assistant configuration files
- Adjust entity IDs and thresholds to match your setup
- Restart Home Assistant and verify automation behavior
Includes:
- SG Ready state indicators
- Heat pump metrics
- Solar production and battery status
- Manual override buttons
See docs/sg-ready-overview.md for a detailed explanation of SG Ready modes and how they interact with your energy system.
