MQTT

My custom-built Smart Home Energy Management System (EMS)

Developed an inverter abstraction layer for multi-brand solar inverter connectivity, running on the SunBerry.

A self-designed and built LoRa sensor: an ultra-low-power, long-range sensing and control board that can run for years on battery power, and programmable like a typical Arduino-based system.

Builded my own home automation including energy management system, with Home Assistant, Home Logic, and MQTT.
