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.

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.

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.
