How the IOTel System Saves About 20 kWh in Every Room: Real Hotel Experience

← Back to Blog

Introduction

Modern hotels strive to reduce costs without compromising guest comfort. One of the key expense items remains electricity — primarily air conditioning. The IOTel project offers a more advanced approach to room automation, which effectively reduces consumption and eliminates the possibility of guests bypassing the system.

In this article, we'll break down how the solution works, why it outperforms energy-saving card slots, and show real measurement results from an active hotel.

The Energy Saving Problem in Hotels: Where Kilowatts Are Lost

The most common solution in hotels is the energy-saving card slot, where a guest inserts a key card. However, this system has significant weaknesses:

❌ Main Drawbacks of Card Slots:

  • Easy to bypass: Guests can leave a spare card in the slot, and the AC will run 24/7.
  • Use of third-party cards: Any RFID card can be used to keep the power on.
  • Inconvenience: Hotels often issue only one card per room, which is inconvenient for guests.
  • No window control: The slot doesn't monitor open windows or doors — the AC continues to cool the "outside."
  • Lack of analytics: Staff cannot see real-time occupancy or access logs.

As a result, the system often fails to perform its function, and the hotel continues to lose electricity and money.

How the IOTel System Works

The IOTel room automation system uses a more accurate and advanced set of sensors:

✅ IOTel System Components:

  • Motion sensors in all areas, including bathrooms.
  • Door and window sensors (entrance, balcony, windows).
  • Controller that analyzes the room's status in real-time.
  • Management capabilities via Wi-Fi or server.
  • Free software for access control, occupancy tracking, and automation modes.

What This Means in Practice:

🌡️ Automatic Shut-off for Open Windows

The system turns off the air conditioning when windows or doors are opened. This eliminates the largest source of waste — cooling the street.

⚡ Complete Shutdown of Empty Rooms

When the room is vacant, the system shuts down all electricity. If necessary, it can even shut off the water for maximum safety.

🎯 Hands-free Operation

No cards required — the system automatically recognizes guest presence via motion sensors, providing maximum comfort for the client.

🛡️ Impossible to Bypass

Unlike card slots, the IOTel system cannot be fooled. Sensors record the actual situation in the room.

Additional Features (Not Available in Card Slots)

IOTel is not just automation, but a hotel management tool:

🔐 Access Control

Crucial for seasonal hotels: during the off-season, the system acts as a security alarm. Any unauthorized door opening is instantly recorded.

📊 Real Occupancy Monitoring

Allows you to eliminate unauthorized room occupancy by staff or third parties. You'll know exactly if someone was in the room when the door opened.

⭐ "VIP / All Inclusive" Mode

For a specified period, the room operates in luxury mode — AC and power work without restrictions. When the guest checks out, the room automatically returns to normal mode.

Real Hotel Experiment: Consumption Measurements

🔬 Experiment Conditions:

A hotel conducted a 6-day experiment with precise measurements:

  • 3 days — system was turned OFF
  • 3 days — system was turned ON
  • Hotel occupancy was identical during both periods.

📈 Experiment Results:

Consumption difference per room: ~20 kWh/day
Savings for a 50-room hotel: 1,000 kWh/day
Monthly savings: 30,000 kWh
Estimated monetary savings: Significant reduction in utility bills

Why Did This Happen?

Main cause of loss: Guests often don't turn off the AC from check-in until check-out. It runs even with open doors, windows, or in an empty room.

IOTel Solution: Completely eliminates these scenarios — providing consistent savings without compromising comfort.
