Smart hotels · Greponis × Hotelio

The hotel that runs itself.

From the moment a booking is created to the moment the guest opens their room door, nobody needs to make a phone call, hand over a key or set a thermostat. Hotelio runs operations. Greponis brings the building into the same system.

From booking to the door.

Seven stages. At none of them does anyone on staff need to type, call or wait, except for exceptions.

01 · Booking

The booking is made, the guest file already exists

The reservation arrives from the PMS or the channel manager and Hotelio reads it immediately. The guest file is created. Nobody types anything a second time.

02 · Messaging

The guest is informed in their own language

Confirmation and instructions reach the guest by message on their phone. The AI answers 24/7 on WhatsApp, phone and email in 30+ languages, and hands anything it cannot handle to a person.

03 · Online check-in

Reception does not wait at the desk

Through the guest portal the guest fills in their details and settles any payments due. By the time they arrive, check-in is already done.

04 · Room preparation

The room is ready before the guest is

Housekeeping is notified and the room is marked ready once cleaned. Air conditioning comes out of energy-saving mode before arrival, so the room greets the guest at a comfortable temperature.

05 · The door

A personal code instead of a key

The guest receives a code for the property entrance and for their room, valid only for their stay. There is no key to hand over, lose or copy.

06 · The stay

The room adjusts itself through sensors

Air conditioning pauses when the balcony door opens and ventilation follows humidity. If the guest needs something, they ask from their phone and the AI either handles it or passes it to staff.

07 · Departure

The room returns to readiness by itself

The code expires, the room drops into energy-saving mode and joins the cleaning list. Reception sees the status of every room and the energy use on a single screen.

One partner for the building, one platform for operations.

You do not change your PMS. Hotelio connects to the one you already use and adds an AI staff layer on top.

Smart hotel FAQ.

Can a hotel run automatically from the moment a booking is created until the guest enters the room?

Yes. Hotelio reads the booking, informs the guest, completes online check-in and notifies housekeeping. Greponis building automation prepares the room and gives the guest a personal door code. Staff step in only for exceptions.

Do I need to replace my PMS?

No. Hotelio connects to the PMS you already use and does not replace it.

Which languages does guest communication cover?

Hotelio replies automatically in the guest's own language, in 30+ languages, around the clock, over WhatsApp, phone and email.

What happens when the AI cannot handle a request?

Hotelio works within the rules the property sets and hands anything it cannot handle to a person. Staff approve, the AI proposes.

Who installs the hardware and who provides the software?

Greponis handles the survey, installation and maintenance of the equipment in the building. Hotelio provides the software and trains the AI on your property. You get one partner for the building and one platform for operations.

Can this be done in a hotel that is already operating?

After a site survey, yes. The survey shows which existing equipment can be connected and what needs to be added.

How much does a smart hotel cost?

It depends on the size of the hotel and the functions you choose. We do not publish prices. The site visit and the written proposal are free and carry no obligation.
