Building an Home Automation system using PyQt, MQTT and Arduino
summary
A working home automation stack ties a PyQt GUI to an MQTT broker and multiple Arduino microcontrollers that publish temperature, humidity and alarm topics; sensors publish per-room topics and a local broker routes messages so mobile and web clients see real‑time updates. The system supports multithreading, handles on the order of 100 concurrent device connections, runs locally without cloud, and demonstrates switching appliances, notifications and a live demo of data flowing end‑to‑end.
