self-consumption

Solar Energy Management for Home Assistant — automate solar surplus across EV, battery, heat pump & appliances. Tariff-aware, multi-brand, 100% local.

The microcontroller regularly requests the energy flow from the energy meter. When surplus energy is available, it commands the Robotdyn dimmer to deliver more energy to a water heater.

Componente per Home Assistant per massimizzare il surplus solare tramite climatizzazione adattiva, protezione batteria e logiche multisplit.

Run a pool pump, water heater or any switchable load on PV surplus, with a guaranteed minimum runtime per day. Forecast-aware, battery-aware, built for balcony solar and limited inverters.

Independent Arduino GIGA R1 monitor & watchdog for a Shelly Pro 3EM + Zendure SolarFlow setup — live grid/phase data, daily kWh balance, and red/yellow alarms (grid-dumping, deep discharge, BMS) with self-supervision.

TED Energy Controller — multi-brand HEMS for Home Assistant. Controls all your solar inverters and home batteries, whatever their brand (Zendure, Anker SOLIX, Marstek, Deye, Huawei, Victron…), as one virtual battery: zero export, off-peak charging, runs locally.

Progetto per monitor autoconsumo, produzione, consumo e scambio energia elettrica

Independent load orchestration for Victron Venus OS systems and Shelly devices.

Public database of 56 hybrid inverter models compatible with second-life EV battery packs: Deye, SOFAR, GoodWe, SolaX, SMA, Fronius and more. DC voltage windows and battery protocols.

Solar self-consumption advisor: watches the solar forecast, grid carbon intensity, and peak tariffs, then names the best hours to run appliances or charge an EV.

Home Assistant integration that spends exported electricity on loads that can wait — including behind a meter that cannot report exports, like a Linky over TIC.

Smart PV Meter (SPVM) - Home Assistant integration for real-time solar surplus calculation and energy optimization

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.

Budget ESP32-S3 monitor & watchdog for a Shelly Pro 3EM + Zendure SolarFlow setup — live grid/phase data, daily kWh balance, red/yellow alarms (grid-dumping, deep discharge, BMS); 7″ display via LovyanGFX. Sibling of gigar1-shelly-zendure-monitor.
