How many times a day do you wonder if the room is empty?

Think about your last work week. How many times did someone ask — or did you ask yourself — whether a room was empty?

Housekeeping needs to know to go in and clean. Maintenance needs to know to fix something without disturbing the guest. Reception needs to know to offer an early check-in. The supervisor needs to know to organize shifts.

It's the same question, repeated dozens of times a day, by different people, and it almost never has an immediate answer.

What happens when nobody knows

Room 305 has checkout today. It's 10:30 AM. Has the guest left?

• Housekeeping goes up, knocks on the door. No answer. Do I go in? Do I wait? What if they're in the shower?
• Calls reception. Reception doesn't know. They call the guest. No answer.
• The housekeeper skips 305, cleans 306, and has to come back later.
• The supervisor, meanwhile, gets three more calls asking the same thing about other rooms.

According to Switch Hotel Solutions, housekeeping supervisors can spend up to 47 minutes per shift just on coordination calls about room status.

It's not a surprising figure when you think about it. Nobody has the information, so everyone asks.

It's not just housekeeping

The problem looks like a cleaning issue, but it affects the entire hotel:

Maintenance. There's a light bulb to change in room 402. Is someone there? We don't know. We send the technician, they knock, a guest is sleeping. Back to the elevator. Another wasted trip.

Reception. A guest arrives at noon and asks if they can check in already. The room has an 11 AM checkout, but nobody confirmed the guest left. "Sorry, it's not ready yet." It could have been ready an hour ago.

Operations. How many rooms are actually ready right now? Nobody knows for sure. The PMS says one thing, reality says another.

The result: every team wastes time, guests wait longer than necessary, and decisions are made with incomplete information.

Why does this keep happening?

Because most hotels operate with the PMS as their only source of truth. And the PMS knows if a room is booked, but it doesn't know if someone is physically inside.

It's the difference between "this room has checkout today at 11 AM" and "this room has been empty since 8:45 AM."

The first piece of information tells you what should happen. The second tells you what's actually happening. And that second piece of information is what unlocks everything: cleaning, maintenance, early check-in, resource allocation.

The solution is simpler than it seems

A presence sensor in each room. Discreet, no cameras, nothing required from the guest. It detects whether someone is inside and sends that information in real time to a dashboard and, if you want, to the team's phones.

What changes:

• Housekeeping stops knocking on doors. They check the dashboard, see which rooms are empty, and go straight there. No calls, no wasted trips.
• Maintenance knows when to enter. Room 402 has been empty for 2 hours. The technician goes in, fixes the issue, leaves. Without bothering anyone.
• Reception offers early check-in with certainty. "Yes, the room has been ready since 10:15, you can go up." That improves the guest experience with zero extra effort.
• The supervisor manages instead of coordinating. They see the entire hotel on one screen. No more 47 calls per shift.

This isn't future technology

This doesn't require renovations, a PMS change, or construction work. These are wireless sensors that install in under an hour per room and connect to a platform that shows everything in real time.

At Controlá, we've implemented over 50 projects with this type of sensor. What we see every time is the same: the first day the team has real visibility into occupancy, the way they work changes. Not because the technology is spectacular, but because they finally have the information they always needed and never had.

The question that matters

It's not "how much does this cost?" It's: how much is it costing you not to have it?

Every door knocked on unnecessarily. Every coordination call. Every early check-in not offered. Every room left uncleaned on time because nobody knew it was empty.

All of that is solved with a simple, real-time answer: is there someone in the room?
