WiFi-enabled programmable bell system for schools, factories, and facilities

Published Apr 04, 2026

🔴 Problem Identified

Schools and small facilities need affordable programmable bell systems for class changes, breaks, and shift alerts, but commercial solutions cost $500-$1,000+. Small community schools, churches, and facilities can't justify this expense for basic scheduling functionality.

💡 Proposed Solution

A self-contained WiFi bell system that users configure from their phone's browser without apps, cloud services, or subscriptions. Features include RTC battery backup, web interface accessible from any device, and a companion controller for managing up to 100 bells from one dashboard.
