Hospitality

Designed for the hospitality sector, these smart energy-saving units (ESUs) regulate electrical power in hotel rooms by switching off non-essential loads when the guest is not present, significantly reducing energy consumption and operational costs. Key tag-based systems activate room power when a guest inserts their key card and turn it off shortly after removal. Models include features like visual indicators and privacy buttons for added convenience. Additionally, advanced guest room controllers with feather-touch panels, Android app integration, and aesthetic customization enhance comfort, safety, and user experience. Presevi also offers high-capacity dimmers and controllers for lighting, HVAC, and appliances, tailored for hotels, resorts, public areas, and premium residences.
