SolarEdge2MQTT reads power data from a SolarEdge inverter over Modbus TCP and publishes it to an MQTT broker. It is built for home automation: real-time power flow, battery state, grid import and export, and meter readings, all as MQTT topics that Home Assistant can discover on its own.
Beyond the inverter itself, the service can log in to your SolarEdge monitoring account to read module-level production and control an EV charger, keep a local history in a SQLite file, and forecast tomorrow's production from that history and live weather data.
