Hotels equipped with energy-saving cardholders save energy when the guest removes the card from the holder. In a guest-centric era, it is no longer reasonable to give only one card to guests and expect energy saving by pushing them to remove the card when leaving the room.

There is a battle between a property's energy management goals and those guests who see a card removed from energy saver cardholders as a treat to their comfort. Guests often feel incentives to leave the room card on the holder while they leave the room unoccupied. Removing cards by housekeeping staff at vacant rooms is a widespread practice. Still, it is not efficient and often recognized as a direct overriding of the guests' actions.
Savesor works independently using machine learning. It senses the guest's presence and only does its savings when the room is unoccupied. Guest cards are no longer required to achieve energy-saving goals.

Modern buildings prefer keyless entry solutions. Guests no longer forced to queue at reception to get their room entry cards/keys.
Mobile phones, watches, or a pin code now work as a key to the room.

Traditionally occupancy was detected by placing room key in a holder equipped with a sensor.
While keys became virtual, there is still a need to detect occupancy to save energy, prevent fire hazards, make housekeeping, and minibar filling staff more efficient.

Savesor provides a smart IoT solution powered with machine learning that accurately senses room occupancy. Savesor room units control air conditioning and electrical devices to save energy, give analytics to hotel staff on the occupancy of rooms.
