The room energy-saving switch is a device designed to effectively manage room energy consumption. Typically installed near the room door, these switches facilitate convenient card-based power supply and outage for guests.

When a guest inserts the card into the switch in the room, the power supply is activated, allowing them to use electrical devices. Upon the guest leaving the room and removing the card, the system automatically reduces or turns off energy consumption, minimizing energy waste and effectively lowering energy costs.

Advanced room energy-saving switches can also be linked with electronic hotel door locks. When a guest enters the room and locks the door from inside, the system intelligently supplies power to the room. Additionally, the hotel front desk can remotely control room power, achieving precise energy management.

4. Use of Occupancy Sensors

Occupancy sensors, typically installed indoors, use motion detectors or thermal sensors. When the sensors detect an unoccupied room, this smart technology automatically activates the room’s energy-saving mode, shutting down unnecessary power devices. This intelligent control measure not only reduces energy waste but also prolongs the lifespan of electrical equipment.

Simultaneously, when the sensors detect someone entering, they automatically power up devices, providing a convenient guest experience and increasing guest satisfaction.

For example, at night, if someone enters the bathroom, occupancy sensors can automatically sense and illuminate comfortable lighting. This can avoid the inconvenience of finding the power switch in dim light.

5. Smart Thermostat

The smart thermostat aims to adjust the operation status and efficiency of the hotel’s air conditioning units based on periods to minimize energy consumption. This system is primarily applied in hotel lobbies and guest rooms.

Lobby Temperature Control

The hotel lobby also is open around the clock, its comfort directly affects guests’ impressions of the entire hotel. Through the system backend, management can adjust the air conditioning status in advance by combining people’s flow patterns in the lobby.

In periods of low foot traffic, the temperature could be moderately increased, while during periods of heavy foot traffic, the temperature could be moderately lowered. This ensures indoor comfort while reducing energy consumption, avoiding the comprehensive activation of control devices.
