Pi-Work | 4button IoT Dashboard

⚠️ SAFETY WARNING: Relays and mains electrics are dangerous. This is a description of what worked for me; it is not a guide. Every situation is different. Do not attempt mains wiring unless you are qualified.

About The Project (4button)

A Raspberry Pi based Flask app with HTML, providing a webpage with Login, Pi Data, City Times, four buttons controlling four GPIO pins, a log out, and a remote shutdown/reboot just in case SSH goes down but the site is still up. The next project on the main page will get all this hooked up for remote access.

🌟 Features

Matrix Aesthetic: A clean, hacker-style terminal UI.
Heating Timer: Heating relay includes a 60-minute hardware-software failsafe. If you turn the heating on remotely and forget, the Pi kills the relay after one hour to prevent thermostat conflicts.
Live Pi Vitals: Real-time monitoring of CPU Temperature, System Load, Disk Usage, and Voltage Stability (Throttling check).
World Clocks: London, New York, and Tokyo time-syncing.
