A lightweight, serverless smart home IoT ecosystem built with ESP32-C3 mini and Supabase.

Architecture & Smart Features

• Smart Power Outage Detection: The ESP32-C3 constantly sends timestamped pings to the Supabase SQL database. After a blackout, the device reboots, compares the current time with the last saved ping, and sends an alert via a Telegram Bot stating exactly how long the power was lost.

• Offline Sensor Data Buffering: Continuous environmental logging. Data is buffered offline if Wi-Fi drops and synced to the cloud upon reconnection.

• Web Dashboard & Alarm: Real-time data visualization via interactive charts and integrated security alarm logic.
