# Adafruit IO Smart Home

Day 92 of the 100 Days 100 IoT Projects collection. Board: ESP32.

An ESP32 runs DHT22 sensing plus four relays, all orchestrated through Adafruit IO. A whole smart home on one dashboard.

## How it works

The ESP32 reads a DHT22 and drives four relays, and every one of them appears as a widget on a single Adafruit IO dashboard. Sensing and switching share one cloud home: temperature on a gauge, relays on buttons, the whole house on one screen.

## What you'll learn

- Whole-home dashboards
- Multi-relay orchestration
- Sensor-actuator integration
- Unified cloud control
