Home Assistant on Raspberry Pi 5: Build Your First Smart Home Sensor
Build your own Home Assistant smart home hub on a Raspberry Pi 5 and connect a wireless ESP32 sensor using ESPHome. In this beginner-friendly tutorial, I'll show you how to install Home Assistant OS, set up a Seeed Studio XIAO ESP32-C6, connect a DHT11 temperature and humidity sensor, and bring live sensor data into Home Assistant—all running locally on your network without relying on cloud services.
This project is designed for beginners who want to learn Home Assistant, ESPHome, Raspberry Pi, and ESP32 development through a real-world smart home example that can be expanded later into a full home automation system.

💡 Why This Project?
Many smart home devices require multiple apps and cloud accounts. Home Assistant allows you to bring sensors, devices, and automations together into one local platform that runs on your own hardware. This setup demonstrates a practical smart home workflow using Raspberry Pi 5, ESPHome, and an ESP32 sensor node.
