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.

This repository hosts data and scripts regarding an Economical analysis of household photovoltaic self-consumption in the context of the Vehicle-to-Home (V2H) in Portugal

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

☀️ 🏡 Estimation of photovoltaic solar panels for a house through python.

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.

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

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.

⚡ Nexus-HEMS Dashboard is a real-time Home Energy Management System built for the decentralized energy era. It unifies 5 industrial protocols behind a single dashboard to orchestrate photovoltaic generation, battery storage, heat pumps, EV charging, and building automation — all while optimizing for dynamic electricity tariffs.

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.

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

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.
