SmartEnergySaver AI

Real-time AI that stops electricity waste by alerting when lights/fans are left ON in empty rooms. Save up to ₹500/month with live Firebase IoT sync.

Inspiration

In Indian homes, lights and fans stay ON in empty rooms for hours — my parents' electricity bill was ₹3,200/month, 30% just waste. We realized: people don't waste power on purpose, they just forget. We needed a system that sees waste in real-time and shouts "band karo!"

What it does

SmartEnergySaver AI is a live dashboard that:

  • Detects motion + light levels in each room (PIR + LDR sensors)
  • Flags waste in 60 seconds: "Living Room light ON, no motion for 23 min"
  • Shows exact money loss: "₹0.23 wasted today"
  • One-tap OFF from phone via Firebase
  • 7-day analytics to track savings

How we built it

  • Frontend: Vanilla JS + Chart.js (no frameworks, loads in 1.2s)
  • Backend: Firebase Realtime Database for instant sync
  • Hardware (prototype): ESP32 + PIR, LDR, DHT22, ACS712
  • Design: Mobile-first glassmorphism UI, works on ₹7k phones

We built it as a single HTML file so anyone can run it — just open index.html.

Challenges we ran into

  1. Firebase free tier disconnects — solved with auto-reconnect + local demo mode
  2. Making waste feel real — added ₹ counter instead of just kWh
  3. GitHub Pages doesn't support backend — converted everything to client-side with Firebase
  4. Time crunch — built core in 6 hours, polished UI overnight

Accomplishments that we're proud of

  • Working live demo in <24 hours
  • Real ₹ savings calculation (not fake data)
  • Deployed on both Netlify AND GitHub Pages
  • Mobile responsive, works offline in demo mode
  • Zero-cost stack (Firebase free + GitHub Pages)

What we learned

  • Real-time UX > fancy AI — users want instant feedback
  • Simple math (watts × time × ₹ rate) beats complex ML for this problem
  • Single-file deployment wins hackathons

What's next for SmartEnergySaver AI

  • Auto-cutoff via smart plugs (Tuya API)
  • WhatsApp alerts: "Bedroom fan ON since 2 hours"
  • College hostel pilot — target 20% bill reduction
  • Hindi voice alerts for parents
